* Added restrictions around calling MSCCL++ collectives (#1281)
* Added restriction to non-zero 32-byte multiple message sizes to MSCCL++ AllGather.
* Renamed and refactored some mscclpp types.
* Only transmit the MSCCL++ unique id for non-split comm init. For splitting comm, it has already been transmitted. Instead, save the MSCCL++ communicator in child communicators when calling `ncclCommSplit`. Only destroy MSCCL++ communicators when no RCCL communicators remain that use it. Also improved trace logging.
* Disable MSCCL++ when using managed memory buffers as it isn't supported.
* Added datatype and op constraints for MSCCL++ AllReduce.
* Added documentation on MSCCL++ restrictions to the README.

* Link to libmscclpp_nccl statically (#1282)
* Switched mscclpp_nccl to static linking. Added a build step to rename the NCCL API functions.
* Undid separation of building libmscclpp_nccl from building librccl with MSCCL++ integration. With a static build, it's either fully enabled or fully disabled.
* `nm` isn't always available in docker containers due to being stripped down. Removed use of `nm` in `cmake` and hard-coded the output into mscclpp_nccl_syms.txt.
* Removed IBVerbs dependency for integrating with MSCCL++ (#1313)
* Renamed `RCCL_ENABLE_MSCCLPP` to `RCCL_MSCCLPP_ENABLE` to conform to MSCCL. Set `RCCL_MSCCLPP_ENABLE` to 1 by default if `ENABLE_MSCCLPP` is defined, or 0 otherwise. Added a log warning if `RCCL_MSCCLPP_ENABLE` is set to 1 but `ENABLE_MSCCLPP` is not defined. (#1294)
* Include mscclpp as a git submodule (#1314)
* Added the desired mscclpp commit as a git submodule.
* Added step to automatically checkout the mscclpp submodule if it isn't already present, in case the user forgot to clone recursively.
* Added instruction to README to clone using --recurse-submodules to get the mscclpp submodule.
* Enabled MSCCL++ feature build.

Add scalable init API
* Add new ncclCommInitRankScalable to allow for passing multiple
unique IDs to the init function.
* Spreads the load onto multiple bootstrap roots, allowing for
constant bootstrap time.
* Requires multiple ranks to create a unique ID, and the CPU-side
ID exchange code to call allgather[v] instead of broadcast.
Accelerate init bootstrap operations
* Reduce the number of calls to allgather.
* Allow roots to reply early to ranks when information is already
available.
* Add an option to use ncclNet instead of sockets to perform
bootstrap allgather operations.
Add PAT algorithms for Allgather and ReduceScatter
* Parallel Aggregated Trees, variation of Bruck algorithm.
* Logarithmic number of network steps for small sizes at scale.
* Only supports one rank per node at the moment.
Add support for registered buffers for intra-node communication.
* Allow registered user buffers to be accessed directly intra-node
* Avoids extra copies in algorithms which permit it, saving
memory bandwidth and helping with compute overlap.
Add profiler plugin API
* New plugin API for profiling
* Supports various levels of profiling, with a hierarchy.
Asynchronous graph allocation
* Make calls to cudaMalloc and cudaMemcpy during graph allocation
asynchronous.
* Significantly speeds up graph capture.
Use fatal IB asynchronous events to stop network operation
* Avoids many other error messages
* Only fatal errors are affected; potentially transient errors
(e.g. port down) do not cause an immediate stop.
Set P2P level to PXB on AMD CPUs when using more than 2 GPUs per node
* P2P would cause a significant performance degradation when using
many GPUs, and therefore many interleaved data flows.
* Disable P2P through the CPU when we have 3+ GPUs per node; keep it
enabled when we only have 2 GPUs.
Improve the init logs to report the real NCCL function.
* Make the log report ncclCommInitRank or ncclCommSplit, rather than
the generic ncclCommInitRankFunc.
Add a parameter to set the location of the user configuration file.
* Add NCCL_CONF_FILE environment variable to set where the user's
configuration file resides.
Increase default IB timeout
* Increase IB timeout value from 18 to 20.
* Should help avoid fatal errors on large RoCE systems.
Add new check for nvidia peermem
* On linux kernels 6.6+, /sys/kernel/mm/memory_peers is no longer
present; check for /sys/module/nvidia_peermem/version instead.
Fix old performance regression when mixing small and large operations.
* Improves distribution of work on channels.
Fix crash when NUMA IDs are equal to -1.
* Can happen when a NIC is a virtual NIC, or when linux doesn't
know which NUMA node a device is attached to
* Issue NVIDIA/nccl-tests#233
Fix tree graph search when NCCL_CROSS_NIC is set to 1.
* Would force NCCL to use the balanced_tree pattern, thereby
disabling LL128 on platforms with 1 GPU+1 NIC per PCI switch.
* Would also try to use alternate rings even though it was not
needed.
Compiler tweaks and fixes
* PR #1177
* PR #1228
Fix stack smash
* PR #1325
Fixes for multi-node NVLink + IB operation
Coverity fixes and comments.
