Компания NVIDIA еще раз торжественно представила графический ускоритель Tesla P100 на конференции ISC (International Supercomputing Conference). Напомним, первоначальный анонс Tesla P100 состоялся в апреле 2016 года. Это первая карта NVIDIA Tesla на базе новой архитектуры Pascal. Ускоритель предназначен для масштабируемых дата-центров. Компания позиционирует новый ускоритель как самый продвинутый адаптер среди  ускорителей для дата-центров.

Ускоритель построен на базе GPU GP100 с 15,3 млрд транзисторов, созданного по 16-нанометровому техпроцессу FinFET. В GPU имеется 3584 потоковых процессора, тактовая частота составляет 1328 МГц, 1480 МГц в режиме Boost. Используется 12 или 16 ГБ памяти CoWoS HBM2 с 4096-битной шиной.

Будет доступно две версии NVIDIA Tesla P100 — для серверов и смешанных рабочих станций с интерфейсом PCIe и для серверов с поддержкой NVLink. Показатель TDP в первой версии достигает 250 Вт, во второй — 300 Вт.

Напомним, одной из особенностей стал интерфейс связи между несколькими графическими NVIDIA NVLink распределяет нагрузку между GPU, увеличивая пропускную способность в 5 раз. NVIDIA NVLink позволяет связать вместе до восьми карт Tesla P100. Двунаправленный интерфейс NVIDIA NVLink обладает скоростью 160 ГБ/с. Еще одна особенность — инструкции половинной точности, которые обеспечивают пиковую производительность свыше 21 терафлопса в задачах глубокого обучения. Как отмечает NVIDIA, Tesla P100 — первый ускоритель со скоростью вычислений двойной и одинарной точности в 5 и 10 терафлопс соответственно.

NVIDIA Tesla P100 для PCIe обладает скоростью вычислений двойной и одинарной точности в 4,7 и 9,3 терафлопс соответственно, а также 18,7 терафлопс для вычислений половинной точности с технологией NVIDIA GPU Boost.

NVIDIA Tesla P100 начнет поставляться в четвертом квартале 2016 года. Также она появятся в составе новой системы глубокого обучения NVIDIA DGX-1.
