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
