* Added support for AMD ROCm net-ib alongside vanilla net-ib, with auto-generation to detect conflicts early during NCCL sync and enable future customizations.
* Integrated AMD AINIC support in RCCL for out-of-the-box usage, leveraging performance improvements by default, channel pinning for optimal pipeline performance, and extended support for 32B in-line CTS messages.
* Implemented internal derivation of AINIC-specific flags when RCCL AINIC environment parameter is set, and checks before initializing AINIC net-ib methods.
* Included snapshot of auto-generated ROCm net-ib file (src/transport/net_ib_rocm.cc) for reference.
* Fixed typos in RCCL param API (RCCL_AINIC_ROCE) and dlclose.
* Updated plugin loading logic:
* Load internal ROCmIB plugin only when NCCL_NET_PLUGIN is not set.
* Load default internal net-ib only when not AINIC and no external plugin env is set.
* Update unit tests for alt_rsmi impl
- Create distinct test executable for alt_rsmi testing
- Updated alt_rsmi tests to use public methods
- Compiles alt_rsmi.cc with ARSMI_TEST_BUILD
- Enables external linkage of internal variables
- Only for AltRsmiTests.cpp that manipulates internals
- Clean separation for test behavior
* Address review comments
* restore hidden symbol visibility
* 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
* Implements casting key loads and stores to address_space(1) so that vector global load and store instructions are emitted by the compiler instead of more costly flat loads and stores
* Removes nontemporality from some key stores for gfx950.
* Support pipelining codegen and template specialization
* Support ReduceCopy pipelining for AllReduce, ReduceScatter, and Reduce (currently enabled for bfloat16)
* Remove need for FUNC_INDEX_TOTAL
* Add pipeline field to device function key construction logic
* Avoid unneeded codegen for LL/LL64 kernels
* Modify conditions and add pipeline dtypes env
* Optimize selection for both gfx942 and gfx950
* Increase pipeline bitfield width
* Use __forceinline__ for all device functions
* Realign reduceCopy with original form
* Add opt-out option to enable perf debugs
* Remove force-reduce-pipelining option from README
* Update CHANGELOG.md

Leverages the traits of extended-scope fine-grain memory to get rid of a device-scope acquire-release fence. This improves throughput for single node workloads on gfx942 and gfx950 for some input sizes (e.g., ~32 MiB to about 256 MiB) when using the simple protocol. Multinode workloads on MI300X see a smaller but statistically significant uplift for some message sizes. Runtime disablement is supported via setting the environment variable RCCL_GFX942_CHEAP_FENCE_ON to 0.
- Introduced double-buffering to reduce copy overhead and overlap BF16 arithmetic with data prefetching.
- Aimed to improve performance of reduction-based collectives by up to 10%.
- Implemented based on recommendations from Guennadi Riguer (AMD)
- Added --force-reduce-pipeline option to install.sh to activate this optimization for BF16 reductions.
- Feature is disabled by default to prevent regressions with large messages until auto-tuning logic is upstreamed.

* Support fused all reduce and elementwise operations
Add additional "acc" parameter to RCCL Replayer logs
Add flag which indicates availability of new API
* Fix Recorder json parsing
* Remove unreachable code
* Remove extra acc pointer check
* .
* Revert "[DEVICE] Adding ability to choose unroll factor at runtime (#1734)"
This reverts commit 9d72be7b2f.
* Use noinline to reduce kernels linking time
* Don't use noinline for gfx942 and gfx950 to avoid perf regression

Boosts single node bfloat16 allreduce performance by up to 20% for some data sizes and provides gating with the RCCL_GFX942_CHEAP_FENCE_OFF environment variable
* Increased max stack size to 640
* Added new binary for executing unit tests
Added new unit tests for argcheck.cc and alt_rsmi.cc files
Modified the method to execute unit tests to cover static methods
by using a bash script to convert static to non-static functions
and variables on the fly restricted to debug build type.
* Add support for extended fine-grained system memory pool
* Use hipHostRegisterUncached
* Add "sc0 sc1" flags for LL store on gfx950
* Update after HIP flag is changed to hipExtHostRegisterUncached
This feature tracks the proxy events and status of each send/recv op. ProxyTrace keeps a fixed number of active ops in host mem and dumps the status of each op when the program crashes or hangs.
* Make offload-compress the default
* Add guard for --offload-compress since it was introduced in ROCm 6.2
* Address some of Nilesh's feedback.
* Reorganize for code cleanliness
* Improve comment
* Compress gpu code at link and compile time
