Сетевая инфраструктура
The fabrics that turn tens of thousands of accelerators into one machine: scale-up interconnects, scale-out networks and the optics underneath.
Заметки с места событий
Неочевидная истина большого ИИ: сеть определяет, сколько вашего кластера за миллиард долларов вы реально используете. Война, за которой стоит следить, — медная империя против открытого Ethernet: частные фабрики NVIDIA против общего открытого стандарта.
Начните с этих трёх

NVLink & NVSwitch
Глубочайший ров NVIDIA, отлитый в меди. Причина, по которой 72 GPU могут работать как единое целое.
UE
Ultra Ethernet
Коллективный ответ индустрии, опубликованный как единая открытая спецификация в 2025 году.
8&
800G & 1.6T Optics
Куда тихо утекают деньги — кластеры потребляют их сотнями тысяч.
