## Description
|
||||
|
||||
This directory contains automated tests for the RCCL (ROCm Communication Collectives Library) CSV Tuner Plugin. The test suite validates the functionality of the CSV-based tuning plugin across different collective operations (AllReduce, Broadcast, Reduce, AllGather, and ReduceScatter) and various configuration scenarios.
|
||||
This directory contains automated tests for RCCL (ROCm Communication Collectives Library) plugins:
|
||||
|
||||
1. **CSV Tuner Plugin**: Validates the functionality of the CSV-based tuning plugin across different collective operations (AllReduce, Broadcast, Reduce, AllGather, and ReduceScatter) and various configuration scenarios.
|
||||
|
||||
2. **Profiler Plugin**: Validates the profiler plugin that captures detailed runtime events for collective and P2P operations, including Group, Collective, P2P, ProxyOp, ProxyStep, and GPU kernel events.
|
||||
|
||||
The tests are written in Python using the pytest framework, making it easy to run, maintain, and extend the test coverage.
