HIP and Language Runtimes

HIP Runtime

Fixes

A bug was discovered in the hip graph capture implementation in ROCm™ 5.2.0. If the same kernel is called twice (with different argument values) in a graph capture, the implementation was only keeping the argument values for the second kernel call. This bug has now been fixed.
A bug was introduced in the hiprtc implementation in ROCm™ 5.2.0. Due to the bug, hiprtcGetLoweredName would fail for named expressions that had a whitespace in it. For example, the named expression "my_sqrt<complex>" would pass but "my_sqrt<complex >" would fail. This bug has now been fixed.

Added

Compatibility with NCCL 2.12.10
Packages for test and benchmark executables on all supported OSes using CPack.
Adding custom signal handler - opt-in with RCCL_ENABLE_SIGNALHANDLER=1
- Additional details provided if Binary File Descriptor library (BFD) is pre-installed
Adding experimental support for using multiple ranks per device
- Requires using a new interface to create communicator (ncclCommInitRankMulti), please refer to the interface documentation for details.
- To avoid potential deadlocks, user might have to set an environment variables increasing the number of hardware queues (e.g. export GPU_MAX_HW_QUEUES=16)
Adding support for reusing ports in NET/IB channels
- Opt-in with NCCL_IB_SOCK_CLIENT_PORT_REUSE=1 and NCCL_IB_SOCK_SERVER_PORT_REUSE=1
- When "Call to bind failed : Address already in use" error happens in large-scale AlltoAll (e.g., >=64 MI200 nodes), users are suggested to opt-in either one or both of the options to resolve the massive port usage issue
- Avoid using NCCL_IB_SOCK_SERVER_PORT_REUSE when NCCL_NCHANNELS_PER_NET_PEER is tuned >1
