Who This Solution Is For
Business Benefits
Low-latency collectives
NVLink-connected SXM4 GPUs accelerate all-reduce and halo exchange in tightly-coupled simulation codes.
Dense compute, smaller footprint
A four-GPU SXM4 node delivers HPC throughput where an eight-GPU chassis exceeds power or space limits.
Double-precision strength
A100 FP64 and Tensor Core FP64 accelerate scientific workloads beyond AI-only accelerators.
Typical Business Use Cases
Molecular dynamics and CFD simulation
Climate and physics modeling
GPU-accelerated linear algebra and solvers
Coupled multi-GPU HPC research workloads
Industry Applications

Frequently Asked Questions
Why SXM4 rather than PCIe for HPC?
SXM4 NVLink delivers higher GPU-to-GPU bandwidth and lower latency than PCIe, which benefits the frequent collective operations common in tightly-coupled simulation.
Does the A100 handle double-precision work?
Yes. The A100 provides strong FP64 plus Tensor Core FP64 acceleration, making it well suited to scientific and engineering simulation, not only AI.
Can these nodes form an HPC cluster?
Yes. Integrated InfiniBand HDR lets nodes connect into a low-latency fabric, which we size to your simulation scale during specification.
