This release is intended only for use on AWS P* instances. A general release that supports other Libfabric networks will be made in the near future. This is a bugfix release which requires Libfabric v1.18.0 or later and supports NCCL 2.21.5-1 while maintaining backward compatibility with older NCCL versions (NCCL v2.4.8 and later).

Bug Fixes:

  • Improved tuner model to make better decisions on P5 instances.
  • Added support, in RDMA protocol, for truncation when receiving a size in the isend call greater than the size in the correspond irecv.
  • Fixed bug that prevented the tuner from getting loaded with NCCL 2.19 and 2.20.
  • Fixed logging statement regarding if a domain is created per thread or per process.
  • Updated plugin to not advertise global MR support, to avoid a performance regression in user-registered buffers.

The plugin has been tested with following libfabric providers using tests bundled in the source code and nccl-tests suite:

  • efa
