ROCm release v7.2.2

rocm-7.2.1

ROCm release v7.2.1

ROCm release v7.2.0 (rocSHMEM v3.2.0)

rocSHMEM 3.2.0 for ROCm 7.2.0

Added

• Added the GDA conduit for AMD Pensando IONIC

Changed

• Dependency libraries are loaded dynamically
• The following APIs now have an implementation for the GDA conduit
  • rocshmem_p
  • fetching atomics rochsmem_<TYPE>_fetch_<op>
  • collective APIs
• The following APIs now have an implementation for the IPC conduit
  • rocshmem_<TYPE>_atomic_{and,or,xor,swap}
  • rocshmem_<TYPE>_atomic_fetch_{and,or,xor,swap}

Known issues

• Only 64bit rocSHMEM atomic APIs are implemented for the GDA conduit

ROCm v7.1.1 (rocSHMEM 3.1.0)

ROCm release v7.1.1

rocSHMEM 3.1.0

Added

• Allowed IPC, RO, and GDA backends to be selected at runtime.
• GDA (GPUDirect Async) conduit for different NIC vendors:
  • Broadcom BNXT_RE (Thor 2)
  • Mellanox MLX5 (IB and RoCE ConnectX-7)
• New APIs:
  rocshmem_get_device_ctx

Changed

• The following APIs have been deprecated:
  • rocshmem_wg_init
  • rocshmem_wg_finalize
  • rocshmem_wg_init_thread
• rocshmem_ptr can now return non-null pointer to a shared memory region when the IPC transport is available to reach that region. Previously, it would return a null pointer.
• ROCSHMEM_RO_DISABLE_IPC is renamed to ROCSHMEM_DISABLE_MIXED_IPC.
  • This environment variable wasn’t documented in earlier releases. It’s now documented.

Removed

• rocSHMEM no longer requires rocPRIM and rocThrust as dependencies.
• Removed MPI compile-time dependency.

Known issues

• Only a subset of rocSHMEM APIs are implemented for the GDA conduit.
