ClusterKit

ClusterKit is a multipurpose node assessment tool for high-performance clusters, aimed at conducting the following tests:

• General Assessments: Latency, bandwidth, effective bandwidth, memory bandwidth, ordered ring bandwidth, and random ring bandwidth

• GPU Communication Tests: Memory bandwidth, GPU-GPU latency and bandwidth, GPU-Host latency and bandwidth, and NCCL bandwidth and latency

• Collective Evaluations: Barrier, allreduce, broadcast, alltoall, and NCCL

• Bisectional Bandwidth

• CPU/GPU Stress

• It is recommended to install ClusterKit on a shared directory.

• If such directory does not exist - make sure that all scripts are available on all the hosts in the exact same directory.

• SLURM or passwordless ssh connectivity across the hosts.
