* Add ncclCommDump API
* remove trailing whitespace changes
* Add more proxy trace timestamps
* Add facebook_rccl namespace before proxyTrace timestamp call
* Clean up ProxyTrae construction
* Move updateProxyOpCounter to member function
* Move setProxyOpTimestamp to member function
* Move addNewProxyOp to member function
* Make internal methods private
* Make ProxyTrace thread safe
* Fix unit tests
* Fix overwritten ProxyTrace DONE setting in net.cc
* Fixed parsing of env var lists which were overwriting the mutable env var string and polluting future parses.
* Fixed all tests to obey UT_DATATYPES and UT_REDOPS filters.
* Allow tests to bail early via `GTEST_SKIP` if UT_DATATYPES or UT_REDOPS filters give a test size of zero. This allows tests to run much faster with filters on.
* Wrapped the support checks in helper functions on `TestBed`.
* Added single process isolation support to execute tests
* Address review comments
* Update README
* Removed requirement of explicit call to clear method
* Added macros for simplified usage
* Updated tests to use process isolation framework
* Adjust summary output format for isolated tests
* Updated rccl_wrap tests
* Used process isolation in AllocTests
* Used process isolation and fixed failing tests
* Modified test output, added signal handling
Updated macros to handle lambdas
* Convert argcheck tests to isolated tests
* Convert proxy tests to isolated tests
* Remove non-supported test
* Fixed file descriptor handling and clearing env vars for tests
* Added MPI support to execute unit/functional tests
Update node and process validation
Updated node detection count and modified validation method
Update validation logic to include max procs and nodes
* Address review comments
* Fix warnings
* Added a new NET transport test and clean up
* Added MPI test logging mechanism
* Decoupled GTest framework
* Added Net IB functional tests
* Updated with resource guards
* Added NET IB tests and refactored code
* Update P2pWorkflow test
* Update documentation
* Add MPI_TESTS_ENABLED guard to the file
* Fix Shm and NetIB tests
* Applied refactoring and cleanup
* Replaced BufferGuard with AutoGuard
* Modified test debug logging
* Use macro to reduce NcclTypeTraits code duplication
- Replace repetitive template specializations with a single
DEFINE_NCCL_TYPE_TRAIT macro
- Use stringification operator (#) to auto-generate type name strings
- Add #undef to keep macro from polluting namespace
- Makes adding new type mappings trivial
* Unify buffer initialization with generic pattern function
- Remove initializeBufferWithCustomPattern
- Make initializeBufferWithPattern generic with PatternFunc template param
- Now single function handles all patterns via lambda injection
- Updated all test files to use lambdas for pattern generation
- Pattern logic now visible at call site (self-documenting)
* Unify buffer verification with pluggable pattern function
- Remove verifyBufferWithCustomCheck
- Make verifyBufferData generic with PatternFunc template param
- Single function handles all verification patterns via lambda injection
- Updated all test files to use lambdas
- Better defaults: num_samples=0 means verify all elements
- Pattern logic now visible at call site (self-documenting)
* Docs: Add DeviceBufferHelpers section to MPITestRunner.md
- Document new refactored buffer initialization/verification API
- Explain pluggable pattern functions with lambda examples
- Show type mapping and automatic float/int comparison
- Include migration guide from old API to new unified functions
- Demonstrate best practices with real-world examples
- Reference recent refactoring commits (macro-based type traits)
* Docs: Update documentation and examples
- Update on DeviceBufferHelpers
- Update examples using DeviceBufferHelpers methods, e.g. data verification
* Address review comment.
- Replace manual pattern generation loop with initializeBufferWithPattern call
- Use downloadBuffer to get host copy instead of manual hipMemcpy
* Remove non-existent dependency
* Remove duplicate testcase
* Code cleanup in test files
* Moved common constants to base class
* Use one side stream per process
* Handle multiple GPUs per process
* Reset stream when not found
* Address review comments
* Fix missing mutex initializer
* for multinode gfx950, extend AR LL128 up to 256MB, extend RS LL128 up to 8MB per rank, extend AG LL up to 64KB per rank
* dont override direct allgather threshold if set to -1
* restore 2-node AR simple at earlier message sizes than higher multi-node AR
* extend range of LL for single-node RS on gfx950
* update algo/proto for multi-node allreduce on gfx942
* set single-node AR on gfx950 to Tree LL for KB message sizes
* decrease threshold for single node Tree for gfx950 AR
* Fail the job if compiler flag HIP_HOST_UNCACHED_MEMORY is not turned on on mi350x
Place the check after initTransportsRank as the GPU arch info in comm->topo->nodes info is populated after that.
* Update src/init.cc to use ERROR instead of WARN

* Enhance logging in NCCL initialization
It's convenient to log comms obj and default channels together for debugging
* Add opCount to collDevWork and update increment logic
Added opCount to collDevWork and incremented it when proxyOpQueue is empty (e.g., for intra-node comms)
* Clarify opCount increment logic in enqueue.cc
Updated comment to clarify incrementing opCount for intranode communications.
* Refactor NCCL_INIT logging format
Updated logging format for NCCL_INIT to improve clarity.
* Remove duplicate INFO logging in init.cc
