| description | Design H-series HPC clusters (HBv3/HBv4, HX) with InfiniBand |
Hpc H Series
When to use this skill
- MPI workloads, CFD, weather, molecular dynamics
Key concepts
- HBv3 — AMD EPYC Milan + 200 Gbps HDR InfiniBand.
- HBv4/HX — Genoa-X with 3D V-Cache + NDR InfiniBand.
- Topology-aware placement via Proximity Placement Group.
- Use SR-IOV InfiniBand drivers from HPC images.
Common pitfalls
- Forgetting PPG — VMs may be spread across spine, killing latency.
