Add support for IB SHARP 1PPN operation with user buffers.
Improve support for MNNVL, add NVLS support and multi-clique support.
* Detect the NVLS clique through NVML
* Exchange XML between peers in the same NVLS clique and fuse XMLs
before creating the topology graph.
* Rework bootstrap allgather algorithms to allow for large allgather
operations intra-node (XML exchange).
Net/IB: add support for dynamic GID detection.
* Automatically select RoCEv2/IPv4 interface by default. Allow to
select IPv6 or even the network/mask.
Reduce NVLS memory usage.
* Add stepSize as property of a connection to allow for different
sizes on different peers; set it to 128K for NVLink SHARP.
Improve tuner loading
* Look for more paths, be more consistent with the network device
plugin.
* Also search for tuner support inside the net plugin.
Improve tuner API
* Add context to support multi-device per process.
Add magic number around comm object to detect comm corruption.
* Add some basic check around communicators so that we can report a
problem when a communicator gets corrupted or a wrong comm pointer
is passed to NCCL.
Fix net/IB error path. Github PR #1164
Fix collnet rail mapping with split comm.
Fix packet reordering issue causing bootstrap mismatch
* Use a different tag in ncclTransportP2pSetup for the connectInfo
exchange and the following barrier.
Fix hang when crossNic is inconsistent between ranks.
Fix minCompCap/maxCompCap computation. Github issue #1184
* initial checkin
* resolve cr comments
* resolve the build issue
* fix the data correctless issue
* update fp8 header file and update the unit test for fp8 support
* remove fp16 from fp8 headers
* fix ut issue and catch up the latest code from develop
* udate according to cr comments
* update ut according to cr comments
* update num floats for each SumPostDiv from 4 to 6
* update fp8 header file name
* fix the typo
