* Revert "[GRAPH] Use channel shuffling only for IB systems (#1228)"
This reverts commit 5be3b713ef.
* Revert "Revert "Changing channel stride for MI300X multinode (#1196)" (#1224)"
This reverts commit ad31d93f3d.
MSCCL can now run in a multi-threaded configuration. To test in the unit tests, added the ENABLE_OPENMP compile definition flag and the --openmp-test-enable flag to the unit test build script. To activate, set the environment variables UT_MULTITHREADED=1 and UT_PROCESS_MASK=1. Set Jenkins to use this mode.
