Custom A100 GPUs

NVIDIA seems to have sold a bunch of A100 variants to European HPC centers that use non-standard quantities of HBM:

• Alps has 96 GB of HBM2e instead of the standard 80 GB HBM2e in second-gen A100 GPUs
• Leonardo has 64 GB of HBM2 instead of the standard 40 GB of HBM2 in first-gen A100 GPUs
