## 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
|
|
|
|
## rocSHMEM 3.1.0 for ROCm 7.1.1
|
|
### Added
|
|
* Allow for IPC, RO, GDA backends to be selected at runtime
|
|
* Added the GDA conduit for different NIC vendors
|
|
* Broadcom BNXT\_RE (Thor 2)
|
|
* Mellanox MLX5 (IB and RoCE ConnectX-7)
|
|
* Added new APIs:
|
|
* `rocshmem_get_device_ctx`
|
|
* `rocshmem_ctx_pe_quiet`
|
|
* `rocshmem_pe_quiet`
|
|
|
|
### 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` was renamed to `ROCSHMEM_DISABLE_MIXED_IPC`.
|
|
This enviroment variable was not documented for prior releases.
|
|
It is now documented to inform users who were using this undocumented feature.
|
|
|
|
### 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
|
|
|
|
## rocSHMEM 3.0.0 for ROCm 7.0.0
