* Add Topologies for 16-GPU gfx942 SuperNode
- Add GigaIO topologies to tools/topo_expl for dev and testing
- Add GigaIO Columba 16 GPU romeModel and adjust topology
matching algorithm in rome_models for 16 GPU system
- Fix bug which failed to match Rome Model when using subsets
of system resources (i.e. ROCR_VISIBLE_DEVICES is set)
- Fixes for topo_expl
* Fix bug w/ 1H16P
[ROCm/rccl commit: a05329bd0d]
* Changing C-strings to be const.
* Changed variable-length arrays to std::vector to avoid warnings. VLA is a compiler extension.
* Changed `#define` inside functions into `constexpr int` to preserve scoping and avoid macro redefinition warnings.
* Disabled warnings for modifying `CMAKE_CXX_FLAGS` caused by `check_symbol_exists`, which temporarily modifies the flag to do a compile check.
* Fixed VLA in rccl UT.

* Reduce linking parallel jobs to avoid OOM in CI
* Workaround issues with UT tests
SWDEV-469533: register spill fix is needed for mainline build
LWPCOMMLIBS-369: cannot enable 112 channels with 80 CUs
Use -parallel-jobs=8 for linking
* CI: do not use -j 16 when building
* CI: use -j 8 when building
* Only reduce parallel linking job for CI extended
* Restore original jenkins command. Change parallel linking jobs in cmake
* Disable MSCCLPP

- Modifies the ring creation algorithm to be friendlier to rail-optimized topologies (should not affect classic fabric topologies)
[ROCm/rccl commit: 4cb62f999a]
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
