8x NVIDIA A100 SXM4 80GB HBM2e
Dual AMD EPYC 7763 (64-core)
1TB–2TB DDR4-3200 ECC
Hot-swap NVMe (configurable, up to 60TB)
Overview
This HGX A100 baseboard couples eight SXM4 A100 80GB GPUs through third-generation NVSwitch for non-blocking all-to-all bandwidth across the node. Nexus Compute specifies, configures, burns-in, and warranty-backs each system through authorized channels for production-grade training and HPC.
Who This Solution Is For
Business Benefits
Full all-to-all bandwidth
NVSwitch links all eight GPUs at 600 GB/s so large models shard efficiently within one node.
Burned-in and validated
Every node is stress-tested across GPUs, fabric, and thermals before it ships.
Proven training platform
The HGX A100 reference design carries mature CUDA, NCCL, and framework support.
Typical Business Use Cases
Large language model pre-training and fine-tuning
Distributed training with NCCL all-reduce
Mixed-precision HPC simulation
Multi-team shared training capacity
Industry Applications
Technical Overview
Built on the NVIDIA HGX A100 8-GPU SXM4 baseboard with six NVSwitch chips delivering 600 GB/s per-GPU bidirectional NVLink bandwidth. Dual-socket AMD EPYC hosts feed the GPUs via PCIe Gen4 with InfiniBand HDR for cluster scaling.

Frequently Asked Questions
How many GPUs can a single HGX A100 node hold?
This configuration is a fixed 8-GPU SXM4 baseboard; all eight A100 80GB GPUs are interconnected by NVSwitch as one tightly-coupled unit.
Is this suited to training or inference?
It is optimized for multi-GPU training and HPC where NVLink all-to-all bandwidth matters; for partitioned serving consider our PCIe MIG configurations.
Can it scale beyond one node?
Yes. The integrated InfiniBand HDR adapters let multiple nodes form a non-blocking training fabric, which we size during specification.
