NVIDIA DGX A100 640GB
Eight A100 80GB GPUs with 640GB HBM2e and MIG partitioning across the node.
Overview
DGX A100 is the Ampere-generation NVIDIA system, with eight A100 80GB SXM4 GPUs, 640GB of HBM2e and dual AMD EPYC processors. Its distinguishing feature is Multi-Instance GPU: each A100 partitions into as many as seven hardware-isolated instances, which makes a single node an unusually good platform for serving many small models or giving separate teams guaranteed capacity on shared hardware.
