You start it yourself once there is stock.

The hardware type or the provider confirms a fast GPU-to-GPU link. Software still has to split the work across GPUs. They never appear as one big memory.

Using several together

Built to be linked. All GPUs in a server are connected with NVLink 5 at up to 1800 GB/s. Software still has to split the work, so the memory doesn't act as one big pool.

Specifications

NVIDIA states up to 160 SMs at 128 CUDA cores per SM, varying by SKU, so core count is null. NVIDIA node memory totals conflict (2.1 vs 2.3 TB). Per-GPU compute figures are derived by dividing NVIDIA's 8-GPU HGX B300 totals by 8; FP4, FP8, FP16, BF16 and INT8 are with sparsity. memoryDataRateGbps is derived (8 TB/s x 8 / 8192 bits). pcieBandwidthGBs is PCIe Gen5 x16, 128 GB/s per NVIDIA.
