It was tested with Libfabric versions up to
[Libfabric v1.18.1](https://github.com/ofiwg/libfabric/releases/tag/v1.18.1).

With NCCL 2.18.5 and v1.7.3-aws of the plugin,
[NVLink SHARP](https://developer.nvidia.com/blog/upgrading-multi-gpu-interconnectivity-with-the-third-generation-nvidia-nvswitch/)
is enabled for the first time on AWS platforms. NVLink SHARP offloads
the computation part of Allreduce collectives to the NVLink fabric,
and involves a different set of algorithms for multi-node parallelism
than previously used. We have seen NVLink SHARP both help and hurt
performance of applications. While NVLink SHARP is enabled by default
if NCCL 2.18.5 or later is used, users may wish to disable it by
setting `NCCL_NVLS_ENABLE=0` in the environment of your job.

New Features:

Bug Fixes:
* Do not disable LL and LL128 protocols on P5 instances.
* Add support for g5.48xlarge instance types.
* Fix a block in use leak in the freelist implementation.
* For NCCL 2.18.5 or later, don't disable NVLS support.
