GigaChat Pro. Технические детали, сдача ЕГЭ и сравнение с конкурентами

8ffe906cd60ac7eb4504f2434eea9974.png

С момента запуска GigaChat прошло около полугода, и за это время у нас появилось более полутора миллионов пользователей. Они активно используют нейросетевые технологии как в работе, так и для развлечения. От пользователей поступают разнообразные запросы: от просьбы сделать краткую выжимку из текста письма до срочного написания поэмы на день рождения коллеги-тестировщика. Мы всегда учитываем обратную связь, которая помогает нам развиваться и внедрять новые идеи.

За последнее время нами были выпущены новые модели и добавлены новые функциональные возможности в сервис. А теперь мы представляем новую нейросетевую модель, у которой более 29 миллиардов параметров. Она успешно прошла тест на ЕГЭ и показала отличные результаты в сравнении с другими системами. Если вы только начинаете интересоваться новыми технологиями в области искусственного интеллекта, то имейте в виду, именно они в ближайшие годы будут формировать наше с вами будущее и давать преимущество тем, кто ими владеет. Давайте познакомимся с ними поближе.

Не ещё один чат

GigaChat и подобные системы, такие, как ChatGPT, являются универсальным инструментом, который позволяет решать творческие, повседневные и аналитические задачи.

Эти системы обычно состоят из нескольких специализированных нейросетевых моделей. Основная модель в этом ансамбле играет роль дирижера, она генерирует креативные ответы на запросы пользователей, взаимодействует с другими моделями и требует особого внимания при обучении и настройке. Помимо основной модели есть и другие, которые расширяют функциональность системы. Например, есть модель Kandinsky, которая может создавать изображения по вашему запросу. Есть модели SaluteSpeech, способные распознавать и синтезировать речь, а также другие, предназначенные для поиска информации во внешних источниках или анализа загружаемых документов.

Приведем пару примеров работы с GigaChat. Запросы могут быть самые разные:

Технические

Даны списки:
a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89]; b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13].

Нужно вернуть список, который состоит из элементов, общих для этих двух списков.

Ответ:

Для решения этой задачи можно использовать встроенную функцию Python set(), которая возвращает уникальные элементы списка. После этого можно преобразовать полученное множество обратно в список с помощью функции list(). В итоге получим список, состоящий из элементов, которые присутствуют и в первом, и во втором списке.

Вот как это можно сделать:
a = [1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89];
b = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13];
c = list(set(a) & set(b)).

После выполнения этого кода переменная c будет содержать список [1, 2, 3, 5, 8, 13].

Процесс создания GigaChat, как и всех других AI-сервисов на основе LLM от ChatGPT до Claude, состоит из двух этапов:

  • Unsupervised Pretraining — учим нейронную сеть на большом количестве легкодоступных данных. GigaChat учится предсказывать следующее слово в текстах из Интернета, книгах и т. д.

  • Alignment — учим нейронную сеть с предыдущего шага следовать инструкциям пользователя, при этом не нарушая никакие законы и не будучи предвзятым. Эта стадия называется alignment (выравнивание), потому что происходит выравнивание желаний и ценностей людей с тем, что генерирует нейронная сеть.

В этой статье мы расскажем про нашу новую pretrain модель, которая легла в основу GigaChat Pro версии.

Возможности новой модели

Самое большое событие релиза — это достижение паритета с ChatGPT-3.5-turbo на метрике SBS (Side-By-Side), где мы просим людей сравнить качество ответов двух моделей.

У SBS есть минусы и поэтому мы дополняем его с помощью автоматических метрик — задач, ответы на которые можно проверить без участия людей. Такие метрики позволяют получать оценку модели очень быстро, а также оценивать Pretrain'ы, которые еще не научились следовать инструкциям.

Для оценки моделей после alignment в автоматических метриках мы используем продуктовые задачи из банка и от внешних клиентов, которые передали нам корзины запросов для оценки, а для оценки pretrain моделей замеряем их на открытых бенчмарках.

SBS (Side-By-Side)

Чтобы посчитать эту метрику, мы выбираем заранее фиксированный набор вопросов и генерируем на них ответы двумя моделями. После этого наши сотрудники выбирают, какая модель ответила лучше на каждый вопрос. Результатов у каждого сравнения может быть 4:

  • Лучше ответила 1-ая модель (всего таких ответов good_a);

  • Лучше ответила 2-ая модель (всего таких ответов good_b);

  • Обе модели ответили хорошо (всего таких ответов both);

  • Обе модели ответили плохо (всего таких ответов none).

Результат SBS считается по формуле:

result\_a = \frac{good\_a + both/2}{good\_a + good\_b + both}

Метрики для таблицы были замерены нами, чтобы сравнивать все модели в одинаковых условиях.

Основной акцент GigaChat’а — это русский язык, но наш pretrain показывает результаты, сравнимые с лучшими Open Source моделями и на английском языке.
На английском MMLU GigaChat Pro до alignment’а дает более высокие результаты, чем LLama-2-34B (64,7% против 62,6%). К сожалению, LLama-2-34B не была выпущена в Open Source, поэтому мы не можем замерить другие метрики вроде MMLU-RU.

На MMLU-RU GigaChat Pro побеждает одну из самых сильных Open Source моделей на данный момент Mistral-7B (57,8% против 50,5%).

Для получения метрики в «продуктовых задачах» мы усреднили результаты замеров на разных датасетах.

Сдача ЕГЭ по обществознанию

GigaChat смог выполнить все задания единого государственного экзамена по обществознанию и набрал 67 баллов, что превышает минимальный балл для подачи в вуз (45 баллов) и средний балл по предмету в 2023 году (56,4 балла). Ответы модели были проверены независимыми экспертами НИУ ВШЭ.

Чтобы получить такой высокий результат, были использованы различные подходы. На итоговое качество влияли инструкции, параметры генерации, размер модели и пайплайн формирования конечного ответа. Так, модели 29b достаточно было просто задать вопрос из ЕГЭ, в то время как 7b конфигурация демонстрировала схожее качество работы уже с помощью цепочки рассуждений, включающей генерацию размышления модели о теме вопроса, критику ответа, исправление ошибок и приведение к требуемому формату.

Результаты экзамена говорят о том, что GigaChat хорошо эрудирован в области социально-юридических наук и способен корректно решить задачи разного типа.

Выводы

GigaChat Pro достиг паритета по способностям с ChatGPT, а на продуктовых задачах в банке обходит его. Сама pretrain модель находится на уровне сильнейших Open Source на английском языке сравнимого размера, а на русском является лидером.

API

Чтобы попросить GigaChat перевести текст, придумать анекдот или сгенерировать картинку с котиком, отлично подходит веб интерфейс, но для более серьезных применений нужен удобный программный интерфейс — API. ChatGPT от OpenAI на днях запретил обращение к своей системе с российских IP-адресов и GigaChat может стать хорошей альтернативой, достигая такого же или лучшего качества на многих задачах, особенно на русском языке.

Мы предоставляем индивидуальным разработчикам специальный freemium тариф на 1 миллион бесплатных токенов. Если их не хватает, можно докупить нужный пакет токенов. Как по мне, так это отличная возможность интегрировать нейросетевые технологии в свой проект или облегчить свои рутинные задачи на работе.

Сценарии работы с API подробно описаны в нашей документации, но в целом алгоритм следующий:

  1. Получить в личном кабинете авторизационные данные, которые будут использоваться для получения временного токена доступа.

curl --location --request POST 'https://ngw.devices.sberbank.ru:9443/api/v2/oauth' \
     --header 'Authorization: Bearer <auth_token>' \
     --header 'RqUID:f2911be0-8c91-4576-bbd4-5238d834c17a' \
     --header 'Content-Type: application/x-www-form-urlencoded' \

}

  1. Использовать токен при обращении к необходимой модели.

    Полный контекст диалога можно передавать в виде массива объектов с ролями user и assistant.

curl -k https://gigachat.devices.sberbank.ru/api/v1/chat/completions \

  -d '{
  "model": "GigaChat-Pro",
  "messages": [
    {
      "role": "user",
      "content": "Придумай альтернативное название для шоколадки Алёнка, 
            оно должно быть необычным и футуристичным"
    }

                    Это название звучит необычно и подразумевает использование
                    передовых технологий в производстве шоколада.",
        "role": "assistant"

  }
}

Отмечу также и еще одно преимущество работы с API. Вы можете самостоятельно управлять семплингом и регулировать параметры top_p, top_k, temperature и repetition_penalty. Это дает вам контроль над тем, будет ли модель генерировать самый вероятный ответ или будет варьировать распределение токенов, чтобы каждый раз выдавать что-то новое. Первый вариант больше подходит для решения задач на классификацию текста или ответа на экзаменационный вопрос, а последний — для генерации креативных материалов, типа маркетинговых текстов.

Техническая часть

Чтобы внести свой вклад в развитие LLM, мы хотим поделиться подробностями нашего пайплайна для pretraining’а. Мы надеемся, что эта информация поможет сообществу развиваться и поддерживать конкурентную среду.

Начнем с общей технической информации о наших моделях. Как и предыдущая модель, новый GigaChat Pro — это декодер трансформер 29 миллиардов параметров с улучшениями для ускорения сходимости и обучения. Для кодирования позиционной информации используются Rotary эмбеддинги. В качестве оптимизатора используется Adam с beta_1=0.99, beta_2=0.95.

Основная часть pretraining’а происходит с контекстом в 4 тысячи токенов. Ближе к концу обучения мы расширяем контекст моделей, используя свойства Rotary эмбеддингов, и заканчиваем обучение с большим контекстом (24-32 тысячи токенов).

Для обучения моделей мы используем фреймворк FSDP (Fully Sharded Data Parallel). По функциональности он очень похож на DeepSpeed и позволяет шардировать модели при обучении, т.е. хранить на каждой GPU только часть весов и состояний оптимизатора.

Большинство Open Source LLM сейчас используют по сути одинаковую архитектуру и процесс обучения нейронной сети. Направления, в которых идет основная конкуренция — это качество pretrain данных, эффективность обучения и небольшие детали в процедуре обучений. Именно про продвижение в этих направлениях мы расскажем далее.

Данные

Данные — это основа всего ML, и обучение больших языковых моделей — это не исключение. Для русской LLM получение качественных данных является особенно сложной задачей. Причин у этого две.

Во-первых, данных на английском языке значительно больше и среди них проще отфильтровать качественные токены.

Во-вторых, самые качественные Open Source датасеты вроде FRW (Falcon Redefined Web) отфильтровывали русские данные, а мультиязычные датасеты не делали акцент на русском языке и в целом слабее FRW.

Для сбора качественного датасета мы решили самостоятельно очистить Common Crawl, сделав акцент на двух языках — русском и английском. Извлечение текста из HTML страниц проводилось с помощью библиотеки trafilatura, а для дальнейшей очистки мы дополнили классические фильтрации на основе эвристик с помощью двухстадийного нейронного классификатора. После очисток применяется дедупликация с помощью SimHash.

6be7ebafb42b05c427109c1b6161af5b.png

Нейронные классификаторы

Основной тип ошибок, которые мы ищем — некорректное извлечение текста из HTML trafilatur’ой. Первая стадия очистки разделяет документы на три цвета — зеленый, желтый и красный.

5ff2bde30a75140006279b98dc003d65.png

Зеленые документы, где ошибок нет, отправляются сразу в обучение, красные, где много проблем, выкидываются, а желтые, где ошибок немного, отправляются на вторую стадию для починки.

Чтобы починить желтые документы, мы ищем плохие абзацы, которые можно убрать из текста, не повредив смысл. Для этого во второй стадии мы рассматриваем каждый абзац отдельно. Документы, где все плохие абзацы можно убрать безболезненно, отправляются в обучение.

2f390562084344b72de6dcbb929aac5d.png

Отладка процесса обучения

Итак, собрав качественные данные, можно приступать к обучению претрейна языковой модели.

GigaChat Pro — трансформер, содержащий 29 миллиардов параметров, и его обучение потребовало от нас решения многих инфраструктурных и архитектурных проблем.

Инициализация модели

Текущие модели настолько большие, что для инференса порой не хватает 80 GB GPU памяти даже на Nvidia-A100. Обучение модели требует еще больше ресурсов, поэтому используется техника шардирования (разбиения) модели между вычислительными узлами, как, например, показано на картинке.

5043ab34194ec4afc1a90ddf9732dc4c.png

Шардировать модель можно тремя способами (рассмотрим случай, когда инициализация слоев происходит независимо друг от друга):

  1. Инициализировать ее полностью на GPU и разослать соответствующие куски модели на другие GPU. Этот подход не сработает, если модель достаточно большая, чтобы не поместиться на одну GPU.

  2. Инициализировать ее на CPU, а потом передавать куски модели на соответствующие GPU. Это намного дольше, чем пункт 1, но зато позволяет использовать оперативную память вычислительного узла, которой зачастую в десятки раз больше, чем на видеокарте.

  3. Если известен алгоритм шардирования модели, то можно сразу произвести инициализацию шардов на нужных GPU без полной инициализации модели в одном месте. Это самый быстрый и самый эффективный по памяти метод (meta init).

Пункт 3 звучит многообещающе, но модель на нем сходилась к довольно высоким значениям лосса, можно сказать, что она практически не обучалась.

Мы нашли баг, когда не передавались правильные инициализации тензоров, и мы обучали модель, инициализированную совершенно случайными числами (инициализация из нужных распределений крайне важна при обучении нейронных сетей). Поправили, и все заработало!

Токенизатор

Токен — некоторая смысловая единица текста (например, подстрока или последовательность байт). Задача токенизатора состоит в том, чтобы эффективно разбивать поступающий в модель текст на подстроки или последовательности байт и сопоставлять им соответствующие токены.

Изначально мы использовали токенизатор со словарем в 132 тысяч токенов и byte-level токенизаций. Это приводило к ряду проблем:

  1. Нестабильность обучения. Происходили взрывы loss-функции из-за большого размера словаря. Это те моменты, когда loss-функция начинала расти вверх и мы теряли десятки итераций обучения, чтобы функция потерь вернулась на свою траекторию.

    5073a6b1a892172863900ffdc3433965.png

  1. Неверная токенизация математических формул. Исходный токенизатор сопоставлял отдельный токен не каждой цифре, а отдельным числам или последовательностям цифр.

  2. Развал модели при более агрессивных параметрах оптимизации (уменьшении Adam epsilon).

Мы попробовали решить их комплексно и обучили новый мультиязычный токенизатор на 42 тысячи токенов. У нас получилась достаточно высокая степень сжатия: в среднем на один токен приходится 3.9 символа текста. Также в новом токенизаторе каждая цифра — отдельный токен, что позволило GigaChat’у лучше понимать математические задачи.

Оптимизатор

В своих обучениях мы используем Decoupled AdamW оптимизатор. Проведя ряд экспериментов с другими оптимизаторами, мы выбрали Adam. Он дает самые низкие значения loss функции, а также достаточно прост во внедрении.

470a4ba96a97cd37ac99e284d2cfd41d.png

Рассмотрим гиперпараметр Epsilon: самая популярная Open Source модель LLaMa-2 обучалась с \epsilon = 1e^{-5}. Наши эксперименты показывают, что:

  1. При большом размере токенизатора уменьшение epsilon может вызывать развал обучения.

  2. Более низкий epsilon с первых шагов и до конца обучения демонстрирует наименьшие значения loss функции, то есть модель обучается лучше.

Таким образом, уменьшение размера словаря токенизатора помогло добиться стабильного обучения при \epsilon = 1e^{-8} и, как следствие, дало возможность достигать более низких значений loss-функции.

ff2f76a68bf97e945688356c28ccfb3b.png

Рестарты обучения

Обучая модель на большом кластере, рестарты могут случаться довольно часто, а остановка обучения довольно болезненна по двум причинам:

  1. Каждые N часов производится сохранение чекпоинта обучения, и, если падение случилось ровно перед сохранением модели, мы теряем N часов работы кластера.

  2. Каждый рестарт также занимает некоторое время.

Чем больше вычислительных узлов одновременно задействовано в обучении, тем больше вероятность, что хотя бы на одном из них произойдет ошибка или поломка оборудования.

Наши коллеги смогли автоматизировать проверки инфраструктуры и заблаговременный вывод оборудования так, что аппаратные причины остановки обучения уменьшились в 20 раз и были сведены к минимуму.

NaN в обучении

Во время pretrain’а GigaChat’а мы столкнулись с тем, что неожиданно число батчей, на которых возникает NaN, начало резко расти. А обновлять NaN’ом веса нельзя, так как это ведет к развалу модели.

03e519638a78b8bef78dc357a2dada97.png

поиске проблемы нам помогла система мониторинга обучения модели. Она собирает информацию о:

  • нормах, минимумах и максимумах весов, их градиентов и соответствующих моментов оптимизатора;

  • нормах, минимумах и максимумах активаций;

  • номерах слоев на forward и backward, где возник NaN;

  • скорости обучения, использования памяти, метриках качества и прочих деталях.

По этим показателям мы заметили, что NaN возникал на backward сразу перед последним слоем, и придумали решение. Обновление весов модели при шардированном обучении обычно реализовано следующим образом:

  1. на каждой GPU считается loss по своему батчу;

  2. с каждой карты аккумулируются и усредняются градиенты;

  3. происходит backward и обновление параметров.

Был модифицирован пункт 2, и те градиенты, где встречаются NaN’ы, мы обнулили. Плюсы и минусы этого подхода:

Плюсы:

  • Зануляем только некоторые градиенты, не пропускаем полностью весь градиентный шаг, эффективнее используем вычислительные ресурсы.

Минусы:

  • Тратим лишние вычислительные ресурсы на проверку на NaN’ы и зануление градиентов. Снижается скорость обучения.

  • Снижаем норму общего градиента с учетом зануления.

Этот трюк помог «вылечить» нашу модель от вычислительной нестабильности. Включив его, число NaN’ов начало падать и в итоге сократилось до нуля.

Позже мы отключили его, и модель продолжила стабильно обучаться.

5c7ab398064f80e28ca4adb60a6a5de7.png

BF16 и FP32

Активации наших моделей для экономии памяти и ускорения подсчетов на обучении хранятся в типе данных bf16 (bfloat16). Этот тип данных имеет тот же range, что и fp32, но меньшую точность. Для аккумуляции градиентов и на этапе вычисления backward мы используем тип fp32, чтобы не допустить потерь в точности и ошибок вычислений.

Ускорение обучения трансформеров

А теперь давайте рассмотрим методы, которые позволили нам ускорить обучение в несколько раз.

Flash Attention 2

FlashAttention реализует механизм внимания (attention is all you need), который оптимизирован для работы с устройствами, имеющими высокую пропускную способность памяти (HBM) и быстродействующую оперативную память (SRAM).

Чем отличается HBM память от SRAM?

SRAM (Static Random Access Memory) и HBM (High Bandwidth Memory) — это два разных типа памяти, которые используются в компьютерных системах. Они отличаются по многим параметрам, включая скорость работы, емкость, стоимость и конструктивные особенности.

SRAM — это тип статической оперативной памяти. Она быстрее и надежнее, чем обычная оперативная память (RAM), но более дорогая и имеет меньшую емкость. SRAM используется в качестве кэш-памяти процессора, так как кэш требует высокой скорости работы.

HBM — это новый тип памяти, который был разработан для использования в графических процессорах и серверах. Она имеет высокую пропускную способность и большую емкость, что позволяет обрабатывать большие объемы данных. HBM также имеет более высокую скорость работы, чем обычная оперативная память.

650721512f6e06ca21ae7ad53e885d08.jpg

Картинка из официального репозитория.

Ускорение достигается путем разбиения входного потока данных на более мелкие блоки и обработки этих блоков параллельно. Это позволяет уменьшить количество обращений к «медленной» памяти, что ускоряет выполнение операций.

Кроме того, FlashAttention выполняет вычисления без сохранения промежуточных результатов в памяти. Это также снижает нагрузку на память и ускоряет выполнение операций. В результате FlashAttention обеспечивает значительный выигрыш в скорости по сравнению со стандартной реализацией механизма внимания и позволяет работать с более длинными последовательностями.

Небольшой технический совет

В реализации из flash-attention обратите внимание на переменную causal.

Во многих реализациях блока внимания на основе flash-attention, подача непустой attention_mask (в том числе состоящей из единиц) сопровождается использованием функции unpad_input на каждом слое. Эта функция вызывает множество последовательных синхронизаций CPU и GPU. Чтобы найти подобные узкие места, можно воспользоваться PyTorch Profiler.

Чем плохи синхронизации между CPU и GPU?

Синхронизация между CPU и GPU может стать узким местом в процессе обработки данных. Это связано с тем, что передача данных между CPU и GPU требует времени и ресурсов, что может замедлить выполнение операций. Кроме того, синхронизация может приводить к простою одного из устройств во время работы другого, что также снижает общую производительность системы.

5b03f59a9f04d7b7d8d4b9d0858c2fec.png

Пример синхронизации CPU & GPU от использования unpad_input. На больших обучениях такие простои могут стоить много миллионов рублей.

Другие fused слои

Что такое fused слои?

Fused слой — это слой, в котором операции выполняются с использованием «слияния» или совместной обработки. В контексте глубокого обучения, «слияние» обычно относится к оптимизации, при которой несколько операций объединяются в одну, чтобы улучшить эффективность вычислений. Например, вместо того, чтобы выполнять операцию свертки, а затем операцию активации, можно объединить их в одну операцию, которая выполняет обе функции одновременно. Это может ускорить выполнение модели и снизить использование памяти.

К примеру, FlashAttention тоже относится к fused слоям. Но он особенный, поэтому мы написали о нем отдельно :).

Мы используем множество фьюзов, вот некоторые из них: Fused Cross-Entropy, Fused LayerNorm, Fused Rotary Embeddings. Каждый дает большой прирост к скорости, а некоторые — огромный выигрыш в видеопамяти.

Подробнее можно почитать в уже классическом блог-посте Making Deep Learning go Brrrr From First Principles

Selective Activation Checkpointing

Что такое Activation Checkpointing?

Activation checkpointing — это техника оптимизации, используемая в глубоком обучении для уменьшения количества памяти, необходимой для хранения активаций между операциями. Вместо того, чтобы сохранять активации для каждого отдельного примера во время обучения, activation checkpointing сохраняет в памяти только часть активаций (например, для каждого второго слоя), а остальные пересчитывает при вычислении backward. Это может существенно снизить использование памяти и дает возможность обучать модели большего размера.

Заметим, что активации модели в зависимости от слоя занимают разное количество видеопамяти и требуют разного количества времени на пересчет.

При достаточно большом контексте (или модели), мы сталкиваемся с тем, что активации всей модели уже не помещаются в видеопамять GPU. Тем не менее, нам нужны активации для подсчета backward pass. Решение — можем хранить только активации для N слоев, а остальные пересчитывать по необходимости вычисления градиентов.

Но вместо того, чтобы хранить все активации для N слоев, мы могли бы сохранять только самые вычислительно-затратные активации на единицу памяти. Это позволит нам сохранять «дорогие» активации для дополнительных M слоев.

Реализации подобных слоев с гибкой настройкой под модель позволили хранить в 5 раз больше вычислительно-затратных на единицу памяти активаций и тем самым увеличить скорость обучения на 10%!

В дополнение, если речь идет о меньших моделях, то снижение потребляемой активациями памяти позволяет отказаться от полного разделения параметров модели по всем GPU (ZeRO 3), оставив только шардирование состояний оптимизатора и градиентов (ZeRO 2), что дает около 20% в производительности.

Как PyTorch управляет памятью?

В PyTorch есть кэширующий аллокатор — это механизм, который позволяет эффективно управлять выделением и освобождением памяти для тензоров. Он использует кэширование для минимизации количества вызовов выделения и освобождения памяти, что может улучшить производительность модели машинного обучения.

Кэширующий аллокатор автоматически выделяет и освобождает память для тензоров, когда они создаются и уничтожаются. Он также может автоматически переносить тензоры из оперативной памяти в VRAM (видеопамять), чтобы ускорить выполнение операций.

При работе на границе видеопамяти GPU кэширующий аллокатор в PyTorch работает на пределе. Это происходит из-за недетерминированного перекрытия computation и communication, что приводит к увеличению доли памяти, недоступной из-за фрагментации, и в конечном итоге может привести к ошибке OOM (out of memory).

Однако, есть способы справиться с этой проблемой. Перед тем как выбросить OOM ошибки пользователю, PyTorch освобождает зарезервированную память, а далее пытается зарезервировать ее снова. В случае успеха порождается реаллокация.

bcb970a57fcd2a832634433765c55d66.png

Подробнее про работу аллокатора и FSDP можно почитать тут.

Реаллокация памяти позволяет продолжать работу, но она может на несколько секунд остановить обучение на одном из узлов. Если у вас большое количество узлов, то может возникнуть ситуация, когда почти все время на каком-то узле будет происходить чистка мусора. Обучение с использованием ZeRO происходит со скоростью самого медленного звена, и эту скорость необходимо выравнивать.

Чтобы минимизировать простой и суммарное время простоя, можно синхронизировать чистку мусора. Таким образом, мы смогли эффективно использовать ресурсы GPU и избежать проблем с памятью.

Улучшаем общение между GPU

Когда у Вас есть кластер с тысячей видеокарт, выстроить эффективное общение между ними — это сложная задача. GPU от Nvidia для этого используют библиотеку NCCL (Никель).

Простыми словами про NCCL.

Nvidia NCCL— это библиотека для организации параллельных вычислений на графических процессорах (GPU) от компании Nvidia.

NCCL позволяет организовать взаимодействие между GPU, которые подключены к одному компьютеру или находятся в одной сети. Библиотека обеспечивает быстрый обмен данными между GPU, что в разы увеличивает скорость работы алгоритмов, которые взаимодействуют с большими объёмами данных.

Помимо скрупулезной настройки NCCL, в наших обучениях нам помогает технология NVIDIA SHARP. SHARP позволяет делать коллективные операции используя вычислительные возможности сетевого оборудования, тем самым уменьшая операции обмена данными.

Так мы смогли сократить передаваемый объем данных по сети, улучшить топологию общения и увеличить скорость обучения на 5%!

    I never thought it would happen to me—but I lost $256,100 in Bitcoin through a shady investment deal. I was shattered, panicked, and convinced my savings were gone forever. Just when I was about to give up, I stumbled upon reviews for FUNDSRETRIEVER, a cyber recovery team with a solid reputation.

    A fraudulent investment scheme operated by BTCMining.limited functions as a fake return scam. In this setup, scammers lure victims with false promises of high returns. Through manipulative tactics, they gain individuals' trust and convince them to invest, ultimately leading to financial loss. If you have ever faced a cyber threat or fallen victim to an online crypto scam and need to reach the authorities, I recommend contacting [email protected], [email protected], WhatsApp +19852969146, telegram @resqprofirm. They are a legitimate team that helps victims of online crypto scams using advanced tools.

    So I ended up losing $38,000 to this platform. At first, they kept asking me to put in more money so I could get into my portfolio. I did that, but then they wouldn’t let me withdraw anything—just kept asking for more deposits. It got way too suspicious, so I stopped. I found this company called ResQProfirm on Google and told them what happened. They got in touch, asked me to walk them through everything, and I gave them all the proof I had. They did an amazing job tracking down my money and getting it back. Big thanks to them at [email protected] and on WhatsApp at +19852969146. Please be careful out there and always research before investing.

    For 43 years, I struggled with bad credit due to my own poor decisions, and my credit score was around 490. When my girlfriend and I decided to buy a house, a mortgage broker informed us that it would be impossible to secure a mortgage with my credit score. As a result, she referred me to a company called HACK MAVENS CREDIT SPECIALIST, assuring me of their professionalism and ability to assist with credit improvement. Upon contacting them, I was impressed by their professionalism and they assured me that they could help. In less than 6 days, my credit score skyrocketed to 785, and they also successfully resolved issues in my credit report, including the bankruptcy. I am incredibly satisfied with their service and would highly recommend HACK MAVENS CREDIT SPECIALIST for reliable credit repairs. You can reach them at H A C K M A V E N S 5 [AT] G M A I L [DOT] COM or at [+] [1] [2 0 9] [4 1 7] – [1 9 5 7]. Thanks to their help, my girlfriend and I are now proud homeowners.

    Back in 2025, I watched my life savings vanish. A thief took every cent. I felt desperate and went looking for a way to get it back. I found a guy here who said he was an expert haha. He talked about special software that could find my missing cash. I trusted him. That was a big mistake. He was just another scammer. I paid him a software fee and then he just stopped answering my texts and ran off with my money too. I felt so ashamed that I kept quiet about it for months. It is hard to admit you got fooled twice. Later on, I found a real pro. she did not use a fancy sales pitch. she just looked at the trans screenshots and followed the path the money took. she worked fast and got my funds back into my account. Having that money back changed everything. I can sleep again. her info; [email protected]. Call/chatroom on Whtasapp/ +44 7476618364.

    There are few companies I trust as much as FUNDSRETRIEVER. When I lost $653,000 in Ethereum to a ruthless scam, I thought my life would never be the same. The betrayal cut deep, but I refused to give up. I searched tirelessly for a legitimate way to recover what was stolen, and finally found FUNDSRETRIEVER—the most competent and compassionate recovery team I could have imagined. They handled my case with precision and care, and in the end, my entire ETH wallet was restored. More than the money, they gave me back my hope and happiness. I'm sharing my story because I want others to know that recovery is possible. If a scam has taken from you, don't hesitate—contact FUNDSRETRIEVER today.

    CRYPTO SCAM RECOVERY SUCCESSFUL – A TESTIMONIAL OF LOST PASSWORD TO YOUR DIGITAL WALLET BACK. My name is Robert Alfred, Am from Australia. I’m sharing my experience in the hope that it helps others who have been victims of crypto scams. A few months ago, I fell victim to a fraudulent crypto investment scheme linked to a broker company. I had invested heavily during a time when Bitcoin prices were rising, thinking it was a good opportunity. Unfortunately, I was scammed out of $120,000 AUD and the broker denied me access to my digital wallet and assets. It was a devastating experience that caused many sleepless nights. Crypto scams are increasingly common and often involve fake trading platforms, phishing attacks, and misleading investment opportunities. In my desperation, a friend from the crypto community recommended Capital Crypto Recovery Service, known for helping victims recover lost or stolen funds. After doing some research and reading multiple positive reviews, I reached out to Capital Crypto Recovery. I provided all the necessary information—wallet addresses, transaction history, and communication logs. Their expert team responded immediately and began investigating. Using advanced blockchain tracking techniques, they were able to trace the stolen Dogecoin, identify the scammer’s wallet, and coordinate with relevant authorities to freeze the funds before they could be moved. Incredibly, within 24 hours, Capital Crypto Recovery successfully recovered the majority of my stolen crypto assets. I was beyond relieved and truly grateful. Their professionalism, transparency, and constant communication throughout the process gave me hope during a very difficult time.

    One of the biggest concerns I have about cryptocurrency is the lack of regulation. It creates opportunities for scammers to invent convincing stories and fraudulent investment schemes. Unfortunately, some social media platforms continue to display these ads because they profit from them, even after users report them.I personally clicked on a Facebook advertisement for a company called Chickenfastmining and ended up losing more than $120,000 in a scam. I reported the ad, but nothing was done. Later, through a Reddit community, I found a recovery service called CYBERBERSPY that, in my personal experience, they helped me recover $110,000 of my lost funds. If you've been a victim of a cryptocurrency scam, don't lose hope. Explore your options carefully, and always verify the legitimacy of any recovery service before trusting them or paying any fees. Based on my own experience, CYBERBERSPY was helpful to me and i was able to recover my funds back, but I encourage everyone to do their own research before using any recovery service.i highly recommend: ([email protected])

    Needs Online Fraud Help Contact Mighty Hacker Recovery https://mightyhackarrecovery.com I lost $292,900 in Bitcoin after investing with an online mining company. After realizing I had been scammed, I spent a long time searching for ways to recover my funds and contacted several services without success. During my research, I came across Mighty Hacker Recovery through Google and YouTube. What caught my attention was that they said they would not require any upfront payment before providing their recovery service. I decided to contact them to discuss my case and understand their process. Throughout the process, they kept me informed about the progress. After several days, I was asked to provide my Bitcoin wallet address, and my case was concluded. Their fee was handled after the service rather than being requested in advance. If you've been the victim of a cryptocurrency scam, it's important to do your own research, ask questions, and carefully evaluate any recovery service before proceeding.

    My experience with OKX has been deeply frustrating. For months, my account withdrawals were restricted with no explanation or resolution. Multiple emails to their support team were ignored, leaving me without answers or reassurance. This complete lack of communication shattered my trust. I ultimately regained access to my funds only through the help of a third-party recovery service, ResQProfirm. What should have been a reliable platform instead made me feel helpless and cut off from my own assets. [email protected], WhatsApp +19852969146, telegram @Resqprofirm

    I can't thank Fundsretriever enough for everything they did for me. My name is Vanessa Conway, and I'm here to tell you my story of how I recovered money I never thought I'd see again. A few months ago, I put a significant amount of money into what looked like a genuine online investment company. At first, it felt real—they showed me fake profits and convinced me to invest even more. But when I tried to cash out, they went quiet and started asking for extra fees. That's when it hit me—I had been scammed. I was heartbroken, frustrated, and didn't know where to turn. That money was my savings—months of hard work gone. Then I found Fundsretriever online. I reached out, hoping for a miracle. Right away, their team made me feel heard. They were responsive, knowledgeable, and walked me through everything. They didn't just take my case—they took it seriously and kept me in the loop every step of the way. I finally felt like I had real experts fighting for me. And guess what? They actually got my money back. It wasn't instant, and it took teamwork, but it happened. When I saw those funds returned, I cried with joy. I'm sharing this so that anyone else out there who's been scammed knows—don't lose hope. Do your research before investing, and stay far away from platforms that promise too much too fast. And if you've already been stung, don't wait—get professional help immediately. Thank you, Fundsretriever, from the bottom of my heart. You didn't just recover my money—you restored my faith. — Vanessa Conway 📧 [email protected] 📱 WhatsApp: +16035121448 💬 Telegram: @Fundsretriever

    A really cool analysis, thank you. I was especially struck by how strictly the order is defined: data processing and formatting come first, with color only at the very end. This really saves you from the typical mistake of "first a pretty palette, then we figure out what the chart is for." And the palette validator with OKLCH + colorblindness check is absolutely fantastic; you almost never see that in regular tools. By the way, while reading about rank-trajectory and the logarithmic scale, I immediately remembered how convenient it is to analyze dynamics on charts in ExpertOption—I've been trading there for quite some time now. When the data is well visualized, decisions are noticeably easier and more relaxed. I also liked the point about "no more than eight colors" and the dual-axis ban. Strict restrictions sometimes actually produce better results than complete freedom. I'll try this approach myself.

    I learned an important lesson after investing in what appeared to be a genuine opportunity. Unfortunately, I was unable to access my funds, which reinforced the importance of carrying out thorough due diligence, checking whether an investment is appropriately regulated, and seeking qualified professional advice rather than relying solely on online reviews or testimonials. During the process of addressing my case, I worked with Mrs. Doris Ashley, who communicated clearly, provided regular updates, and handled the matter in a professional manner. According to my experience, I have recovered $50,000 so far, while efforts to resolve the remaining balance are still in progress. If you wish to contact her, the details I used are: Mrs. Tatiana Sorina

    I was a victim of a crypto theft involving a Pink Drainer, which resulted in the theft of my Wrapped Bitcoin (WBTC) from my Polygon network. The experience was incredibly frustrating and distressing, as I had no idea how to recover my funds. Unfortunately, by the time I noticed the theft, the funds had already been drained to an address that I had no control over, making it seem like an irreversible situation.The attack happened when I clicked on what appeared to be a legitimate link. I didn’t realize at the time that it was a phishing attempt designed to siphon off my private keys and access my wallet. The Pink Drainer, a type of malicious script used by attackers, is specifically designed to exploit such vulnerabilities in crypto wallets. The moment I realized that my WBTC had been drained from my Polygon network. I felt completely helpless, as I didn’t have direct access to the thief's address, and there was no way to reverse the transaction on my own at that point, I started searching for ways to recover my funds, but most resources only offered generic advice that wasn’t practical in this particular case. I quickly realized that if I wanted to have any hope of getting my assets back, I would need professional assistance. After some research, I came across a reliable and trusted recovery team called Aspen Recovery Experts. Their expertise in cryptocurrency recovery, especially in cases like mine, seemed promising.I decided to reach out to Aspen Recovery Experts, and I’m incredibly grateful that I did. Their team of crypto recovery experts was able to help me trace the stolen funds and identify the path the funds took after they left my wallet. Using advanced tools and techniques, they were able to track the transactions on the blockchain, helping me understand where my WBTC had been sent. More importantly, they worked tirelessly to assist me in contacting the necessary parties and even interfaced with blockchain analysts to help facilitate the recovery process.Thanks to their efforts, I was able to successfully recover my stolen funds. The entire process took some time, but the Aspen Recovery Experts dedicated team provided regular updates and kept me informed throughout the process, which gave me a sense of hope and relief during an otherwise stressful time. If you’re ever in a similar situation, I highly recommend reaching out to a trusted recovery team like Aspen Recovery Expertshhh . Their professionalism, knowledge, and expertise were critical in helping me recover my funds and regain control of my crypto assets.

    Excellent analysis, thank you. I was particularly struck by how rigidly the skill sets the order: data processing and form come first, with color coming last. This really cures the habit of "first a pretty palette, then we'll figure it out." A palette validator using OKLCH + color blindness + WCAG is something most chart generators lack. And regarding the boundaries of competence, it's very clear. Where there's a self-checking loop (color), you delegate freely. Where there's a heuristic (form, data interpretation), you remain the final filter. This is a universal principle, not just for /dataviz. By the way, when you look at trading dashboards (including those of decent platforms like ExpertOption), it's immediately clear who thought about readability and who just threw in rainbow lines. Tools like this skill could greatly improve the quality of analytics. Thanks again for the detailed analysis – saved.

    All you need is to hire an expert to help you accomplish that. If there's any need to spy on your partner's phone. From my experience I lacked evidence to confront my husband on my suspicion on his infidelity, until I came across REALCYBERHACKERS which many commend him of assisting them in their spying mission. So I contacted him and he provided me with access into his phone to view all text messages, call logs, WhatsApp messages and even her location. This evidence helped me move him off my life . I recommend you consult REALCYBERHACKERS AT gmail com or whatsapp +14106350697 if you need access to your partner's phone or any kind of hacking, they carry out all kinds of hacking job

    I learned an important lesson after investing in what appeared to be a genuine opportunity. Unfortunately, I was unable to access my funds, which reinforced the importance of carrying out thorough due diligence, checking whether an investment is appropriately regulated, and seeking qualified professional advice rather than relying solely on online reviews or testimonials. During the process of addressing my case, I worked with Mrs. Tatiana Sorina , who communicated clearly, provided regular updates, and handled the matter in a professional manner. According to my experience, I have recovered $50,000 so far, while efforts to resolve the remaining balance are still in progress. If you wish to contact her, the details I used are: Mrs. Tatiana Sorina

    My account was locked, and I couldn’t access my own information until [email protected] +447476618364 whats?up? helped me recover it. This lady hacker was kind and professional, but this experience showed me how risky account lockouts can be. If you’re facing the same problem, do not panic consult her A. S. A. P. Be careful with recovery agents outchea, and research their name, business, and reviews before sharing any details. Never send passwords, security codes, banking information, or copies of your ID unless you’ve confirmed who you’re dealing with. Be wary of promises that sound too good to be true, especially claims that require little information or guarantee instant access with outrageous fees.

    Excellent analysis by /dataviz! I was particularly struck by how strictly the order is defined: "data meaning first, color last" and how the validator actually adjusts the palette according to OKLCH, color blindness, and WCAG standards. These rules greatly improve the quality of charts. By the way, a similar approach to clean and legible charts is highly valued in trading—for example, on the ExpertOption platform, the interface and price visualization are designed to ensure information is read instantly and without unnecessary noise.

    Recovering your lost investment funds as the case might be, is not what you can do alone, you’d require the service of a trained recovery specialist. A recovery specialist is a person or a group of people who are well equipped to work around the brokerage network. They have vast knowledge about the whole network and have the right software and private keys to follow any transaction. I was ripped off trading online to an investment broker, good thing I got every penny back through the help of Gavin ray he’s a genius Contact : Gavinray78 at gmail com or WhatsApp +1 352 322 2096 It is also important to be patient and really calm during the process.

    I fell victim to a freelance web development contract scam that ultimately cost me CAD 4,000. It all started when I came across a job posting on Indeed Canada, a popular online job portal. The position seemed perfect: a freelance web developer role for an established company looking for someone to design and build a fully functional e-commerce website. The job promised a high payment of CAD 20,000 upon successful completion, which sounded like a great opportunity for me to gain experience and earn decent pay.The employer, who introduced himself as a project manager from a "well-known" tech company, was very persuasive and professional in our initial communication. He explained that the project involved developing a user-friendly, responsive online store for their client and that they had a strict timeline to meet. He assured me that the payment would be made promptly after completing the tasks. However, before starting the work, he told me that I would need to pay an upfront fee of CAD 4,000 to cover certain software tools and licensing fees required for the project. This was supposedly a part of their company policy for freelance contractors, ensuring access to their premium resources. The idea of working on a professional project, coupled with the promise of a substantial payout, convinced me to pay the upfront fee.As soon as I made the payment, the project manager became increasingly difficult to reach. He initially responded to my emails and provided some vague instructions on what the project would entail, but as time went on, communication slowed to a complete halt. I never received the required tools or any proper project details. My emails went unanswered, and any attempts to contact the company were met with silence. After waiting for weeks, I realized that I had been scammed.Desperate to recover my money, I turned to TechY Force Cyber Retrieval, a service that specializes in helping victims of online scams. They helped me track the payment and took legal steps to pursue the fraudsters. Through their guidance, I was able to recover the full CAD 4,000. TechY Force Cyber Retrieval worked with my bank to reverse the transaction and liaised with the authorities to trace the scammer's details.This was a hard lesson, and I now know to be highly cautious about online job offers that require upfront payments. It is crucial to research companies thoroughly and avoid any job that seems too good to be true, especially when it involves paying money upfront. WhatsApp https://wa.link/2x6ktp Mail.
