psm2-nccl-0.3.0

Changes:

• Update PSM2-NCCL plugin to support up to NCCL Net API version 8.
• Fix a segfault in psm2_nccl_iflush().
• Update README with information for running with NCCL 2.19 or newer.

psm2-nccl-0.2.2

Changes:

• Re-enable plugin-GPUDirect support by default.
• Null out request objects on completion so NCCL does not test already-complete requests.
• Add information about NCCL_NET_GDR_READ, NCCL_PROTO environment variables to README.

psm2-nccl-0.2.1

Major changes:

• Fix PSM2-NCCL not honoring device number (HFI) passed in from NCCL. This would result in non-deterministic HFI selection by PSM2.

Improvements:

• Warn when NCCL wants to open a communicator on a different device than the one the plugin shared-EP already has opened.
• Print frequent log messages at higher (VERDBG) level, less-frequent messages at lower (INFO, DBG) levels.

psm2-nccl-0.1

Beta release of PSM2-NCCL plugin. See README for build instructions.
