What problem does it solve?
HCCL performance testing for Ascend NPU clusters is complex and time-consuming to set up and validate; this Skill provides a repeatable framework to benchmark distributed communication, verify HCCL functionality, and standardize production testing workflows.
Core Features & Use Cases
- Multi-node benchmarking for HCCL operations (AllReduce, AllGather, AlltoAll, ReduceScatter, etc.) with production-ready workflows.
- Comprehensive pre-flight checks (SSH access, CANN version consistency, NPU health, and MPI environment) to ensure reliable testing.
- Automation tooling including hostfile generation, test orchestration, result parsing, and troubleshooting guidance.
Quick Start
Run the pre-test check and initiate a multi-node HCCL test using the provided scripts with your node list and NPUs.
