This week at SC 25 in St. Louis, a recently implemented Qlustar 14 AI
Kubernetes cluster entered the Top 500 list at rank 90 with a measured
Linpack performance of *19.48 PFlop/s*. This huge success establishes
Qlustar as a proven platform for even the most demanding work-loads in
the AI and HPC universe.
The cluster worker nodes are HGX machines each of them hosting 8 NVIDIA
H100 (80GB HBM3) GPUs which are networked in a rail-optimized fat-tree
NDR Infiniband fabric. Qlustar's new NVIDIA image modules support this
hardware out-of-the-box with optimal performance. The *Qlustar
Kubernetes stack* powering this cluster will become GA and be officially
introduced in an upcoming Qlustar 14 feature release.
