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

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].

Что под капотом

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%).

Автоматические метрики после alignment

GigaChat Pro	50,0	77,4	70,5
GigaChat	45,0	67,1	35,0
ChatGPT	54,0	57,2	52,5

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

В «Ответы по документам» необходимо указать процент аванса и число дней отсрочки, если они указаны в документе.

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:

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 'RqUID:f2911be0-8c91-4576-bbd4-5238d834c17a' \

                    Это название звучит необычно и подразумевает использование

}

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.

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.

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.

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.

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

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.
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.
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:

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.

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

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

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

Рестарты обучения

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

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

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:

на каждой GPU считается loss по своему батчу;
с каждой карты аккумулируются и усредняются градиенты;
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.

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.

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.

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.

Синхронный GarbageCollector

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.

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%!

Итоговые ускорения

Изменение	Кумулятивное повышение throughput
+Flash Attention v2	62,73%
+Fused CE, RMSNorm, RoPE	75,71%
+Уменьшение cpu-gpu sync	82,31%
+Selective checkpointing	103,86%
+Настройка NCCL*	109,02%

Тесты проводились на модели 29B, 128GPU A100. *Эффект от настройки NCCL приведен для 1024 GPU, так как на маленьком числе узлов эффект не так заметен.

Благодарности

Задача по осуществлению такого проекта требует больших усилий, внимательности и вовлеченности. Участвуя в этом процессе, я не перестаю удивляться энтузиазму коллег, генерирующих идеи и готовых воплощать их в жизнь в любое время. Девушки и парни из SberDevices, Sber AI и Научно-исследовательского института искусственного интеллекта AIRI, вы лучшие.

Writing this review is a joy. Marie has provided excellent service ever since I started working with her in early 2018. I was worried I wouldn't be able to get my coins back after they were stolen by hackers. I had no idea where to begin, therefore it was a nightmare for me. However, things became easier for me after my friend sent me to [email protected] and +1 7127594675 on WhatsApp. I'm happy that she was able to retrieve my bitcoin so that I could resume trading.

God bless Capital Crypto Recover Services for the marvelous work you did in my life, I have learned the hard way that even the most sensible investors can fall victim to scams. When my USD was stolen, for anyone who has fallen victim to one of the bitcoin binary investment scams that are currently ongoing, I felt betrayal and upset. But then I was reading a post on site when I saw a testimony of Wendy Taylor online who recommended that Capital Crypto Recovery has helped her recover scammed funds within 24 hours. after reaching out to this cyber security firm that was able to help me recover my stolen digital assets and bitcoin. I’m genuinely blown away by their amazing service and professionalism. I never imagined I’d be able to get my money back until I complained to Capital Crypto Recovery Services about my difficulties and gave all of the necessary paperwork. I was astounded that it took them 12 hours to reclaim my stolen money back. Without a doubt, my USDT assets were successfully recovered from the scam platform, Thank you so much Sir, I strongly recommend Capital Crypto Recover for any of your bitcoin recovery, digital funds recovery, hacking, and cybersecurity concerns.

Hi. Please be wise, do not make the same mistake I had made in the past, I was a victim of bitcoin scam, I saw a glamorous review showering praises and marketing an investment firm, I reached out to them on what their contracts are, and I invested $28,000, which I was promised to get my first 15% profit in weeks, when it’s time to get my profits, I got to know the company was bogus, they kept asking me to invest more and I ran out of patience then requested to have my money back, they refused to answer nor refund my funds, not until a friend of mine introduced me to the NVIDIA TECH HACKERS, so I reached out and after tabling my complaints, they were swift to action and within 36 hours I got back my funds with the due profit. I couldn’t contain the joy in me. I urge you guys to reach out to NVIDIA TECH HACKERS on their email: [email protected]

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.

As time passes, there are an increasing number of frauds involving Bitcoin and other cryptocurrencies. Although there are many individuals who advertise recovering money online, people should use caution in dealing, especially when money is involved. You can trust NVIDIA TECH HACKERS [[email protected]], I promise. They are the top internet recovery company, and as their names indicate, your money is reclaimed as soon as feasible. My bitcoin was successfully retrieved in large part thanks to NVIDIA TECH HACKERS. Ensure that you get top-notch service; NVIDIA TECH HACKERS provides evidence of its work; and payment is only made when the service has been completed to your satisfaction.

Have you gotten yourself involved in a cryptocurrency scam or any scam at all? If yes, know that you are not alone, there are a lot of people in this same situation. I'm a Health Worker and was a victim of a cryptocurrency scam that cost me a lot of money. This happened a few weeks ago, there’s only one solution which is to talk to the right people, if you don’t do this you will end up being really depressed. I was really devastated until went on LinkedIn one evening after my work hours and i saw lots of reviews popped up on my feed about [email protected], I sent an email to the team who came highly recommended - [email protected] I started seeing some hope for myself from the moment I sent them an email. The good part is they made the entire process stress free for me, i literally sat and waited for them to finish and I received what I lost in my wallet

I would recommend NVIDIA TECH HACKERS to anyone that needs this service. I decided to get into crypto investment and I ended up getting my crypto lost to an investor late last year. The guy who was supposed to be managing my account turned out to be a scammer all along. I invested 56,000 USD and at first, my reading and profit margins were looking good. I started getting worried when I couldn’t make withdrawals and realized that I’ve been scammed. I came across some of the testimonials that people said about NVIDIA TECH HACKERS and how helpful he has been in recovering their funds. I immediately contacted him in his mail at [email protected] so I can get his assistance. One week into the recovery process the funds were traced and recovered back from the scammer. I can't appreciate him enough for his professionalism.
17.10.25 20:23 stevekalfman

If you need a hacker for scam crypto recovery or mobile spy access remotely kindly reach out to [email protected] for quick response, I hired this hacker and he did a nice job. before NVIDIA TECH HACKERS, I met with different hacker's online which turns out to be scam, this NVIDIA TECH HACKERS case was different and he is the trusted hacker I can vote and refer.

"In the crypto world, this is great news I want to share. Last year, I fell victim to a scam disguised as a safe investment option. I have invested in crypto trading platforms for about 10yrs thinking I was ensuring myself a retirement income, only to find that all my assets were either frozen, I believed my assets were secure — until I discovered that my BTC funds had been frozen and withdrawals were impossible. It was a devastating moment when I realized I had been scammed, and I thought my Bitcoin was gone forever, Everything changed when a close friend recommended the Capital Crypto Recover Service. Their professionalism, expertise, and dedication enabled me to recover my lost Bitcoin funds back — more than €560.000 DEM to my BTC wallet.

I never imagined I’d fall for a crypto romance scam but it happened. Over the course of a few months, I sent nearly $150,000 worth of Bitcoin to someone I genuinely believed I was building a future with. When they disappeared without a trace, I was left heartbroken, humiliated, and financially devastated. For a long time, I didn’t tell anyone. I felt ashamed. But eventually, while searching for answers, I came across a Reddit thread that mentioned Agent Jasmine Lopez. I reached out, not expecting much. To my surprise, she treated me with kindness, not judgment. She used advanced tools like blockchain forensics, IP tracing, and smart contract analysis and with persistence and legal support, she was able to recover nearly 85% of what I lost. I know not everyone gets that kind of outcome, but thanks to [email protected] WhatsApp at +44 736-644-5035, I’ve started to reclaim not just my assets, but my confidence and peace of mind. If you’re going through something similar, you’re not alone and there is hope.

I was in your shoes when I invested in a bogus binary option and was duped out of $87,000 in BTC, but thanks to the assistance of NVIDIA TECH HACKERS. They helped me get back my BTC. I didn’t trust the Hackers at first, but they were recommended to me by a friend whom I greatly respect. I received my refund in two days.

A few months ago, I fell for what looked like a legitimate online trading platform. The website was sleek, the support team was responsive, and they even showed me fake profit charts that seemed to grow daily. I started small, and after a few test withdrawals worked, I invested more eventually depositing 2 Bitcoin in hopes of long-term returns. But one morning, when I tried to withdraw, everything changed. The platform suddenly locked my account, claiming there were additional fees to release my funds. The support chat stopped responding, and the website started giving error messages. That’s when I realized I’d been scammed. I was devastated. Two Bitcoins wasn’t pocket change, it was my savings. I filed reports online, but everyone told me it was impossible to recover crypto once it’s sent. Then, through a discussion forum, I came across Dexdert Net Recovery, a team specializing in tracing and recovering stolen digital assets. Skeptical but desperate, I reached out. Their response was immediate and professional. They asked for transaction IDs, wallet addresses, screenshots of my correspondence with the fake platform, and any proof of payment I had. Within days, their analysts traced the stolen Bitcoin through multiple wallets using blockchain forensics, They updated me step-by-step, Working with their recovery experts and blockchain partners, Dexdert Net Recovery successfully froze the funds and verified ownership of my wallet. After 2 days of persistence and verification, I finally saw my 2 Bitcoin restored back into my own wallet. I couldn’t believe it. What stood out most wasn’t just that they recovered my funds, but how transparent and supportive the Dexdert team was throughout the process. They educated me on crypto safety, how to spot fake trading sites, and how to secure my digital assets in the future. Dexdert Net Recovery truly lives up to its name. They gave me back not just my Bitcoin, but my peace of mind. Reach Out Information Below Via: Email: ([email protected]) Telegram: (https://t.me/Dexdertprorecovery) WhatsApp: (+1 (859) 609‑4156)

A few months ago, I fell for what looked like a legitimate online trading platform. The website was sleek, the support team was responsive, and they even showed me fake profit charts that seemed to grow daily. I started small, and after a few test withdrawals worked, I invested more eventually depositing 2 Bitcoin in hopes of long-term returns. But one morning, when I tried to withdraw, everything changed. The platform suddenly locked my account, claiming there were additional fees to release my funds. The support chat stopped responding, and the website started giving error messages. That’s when I realized I’d been scammed. I was devastated. Two Bitcoins wasn’t pocket change, it was my savings. I filed reports online, but everyone told me it was impossible to recover crypto once it’s sent. Then, through a discussion forum, I came across Dexdert Net Recovery, a team specializing in tracing and recovering stolen digital assets. Skeptical but desperate, I reached out. Their response was immediate and professional. They asked for transaction IDs, wallet addresses, screenshots of my correspondence with the fake platform, and any proof of payment I had. Within days, their analysts traced the stolen Bitcoin through multiple wallets using blockchain forensics, They updated me step-by-step, Working with their recovery experts and blockchain partners, Dexdert Net Recovery successfully froze the funds and verified ownership of my wallet. After 2 days of persistence and verification, I finally saw my 2 Bitcoin restored back into my own wallet. I couldn’t believe it. What stood out most wasn’t just that they recovered my funds, but how transparent and supportive the Dexdert team was throughout the process. They educated me on crypto safety, how to spot fake trading sites, and how to secure my digital assets in the future. Dexdert Net Recovery truly lives up to its name. They gave me back not just my Bitcoin, but my peace of mind. Reach Out Information Below Via: Email: ([email protected]) Telegram: (https://t.me/Dexdertprorecovery) WhatsApp: (+1 (859) 609‑4156)
