Prevent initialization failures in certain configurations when attempting
to load fp8-specific symmetric multicast kernels on GPUs older than
Blackwell.
[ROCm/rccl commit: 593de54e52]
* 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 4cadf3597c.
* Use noinline to reduce kernels linking time
* Don't use noinline for gfx942 and gfx950 to avoid perf regression

[ROCm/rccl commit: 9a4213356d]
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
[ROCm/rccl commit: 11fabf1de1]
- Added a check to skip issues labeled "ongoing" in the close-old-issues script
- Adjusted the condition to compare both creation and update dates against six months ago
[ROCm/rccl commit: 0d1ece2b43]
* 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.
[ROCm/rccl commit: 275fdd43c1]
We add 3 different issue types issue/question/RFE and add some predefined
questions to speed up the debugging process.
We also add a custom action which will close all issues create mode than 6
months ago which have not been updated for more than a month.
[ROCm/rccl commit: bfedf2629e]
Improve support for DirectNIC (CX8)
* Add support for XDR speed detection.
* When DirectNIC is enabled, report only the RDMA interfaces.
Extend the P2C (PXN over C2C) support to send/receive operations.
Support compilation with GCC 14 (Issues #1743, #1751).
Fix the unloading of network plugins that also provide tuner capability.
Fix the change of the current device across the calls to ncclCommDestroy()
and ncclCommAbort().
A note for users on MNNVL systems: please ensure an adequate stack size for
NCCL threads. While the default Linux stack size limit of 8192 KB is known
to be sufficient, we've seen crashes if the limit is changed to
"unlimited", as it causes the glibc library to unexpectedly *decrease* the
stack size of NCCL's background threads to just 2048 KB. Use "ulimit -s"
in bash to print the current limit; if needed, reset it to 8192 KB using
"ulimit -s 8192" (one also needs to ensure that the new setting is
propagated to other nodes when launching a multi-node NCCL job).
[ROCm/rccl commit: 7c12c627c6]
* Adjust tuning factor impacting more than 2 nodes
* Scale max LL128 size for > 2 nodes
* Retune max LL128 range for N > 2
[ROCm/rccl commit: 058264b3f3]
* removing extra build time by removing the gfx11xx arch from using hip_fp8

[ROCm/rccl commit: 697bee4ee8]
If `find_package()` succeeds to find GTest and `INSTALL_DEPENDENCIES`
is set to OFF, `GTEST_BOTH_LIBRARIES` is not set and thus
`rccl-UnitTests` fails with trying to link unkown symbols.
[ROCm/rccl commit: dac0e528a0]
* 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
[ROCm/rccl commit: 4640ab19b3]
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.
[ROCm/rccl commit: 020dcf0a7c]
When the `roc-obj-ls` executable fails, it sometimes does not return. Since the `execute_process` command will wait until the executable finishes, this means that in some cases, the build will hang indefinitely. There is no error message, and no indication that anything is wrong. This commit fixes that by introducing timeouts into the code and better error reporting.
