This commit adds API documentation for the following host-side
stream functions:

- rocshmem_getmem_on_stream (RMA operations)
- rocshmem_putmem_on_stream (RMA operations)
- rocshmem_putmem_signal_on_stream (signaling operations)
- rocshmem_signal_wait_until_on_stream (point-to-point sync)
The documentation includes function signatures, parameter descriptions,
and detailed explanations of asynchronous behavior and stream handling.
(AI Assist)
* Rename "bytes" -> "nelems"
* Add "_TEST_" to the variables used in tests
* Remove incorrect hipStreamDefault usage
hipStreamDefault is not a default stream. This is a flag.
If stream == nullptr, then just pass it to kernel. It will launch the kernel on the default stream
* Add host-side rocshmem_alltoallmem_on_stream function
Function signature:
rocshmem_alltoallmem_on_stream(rocshmem_team_t team, void *dest,
const void *source, size_t size,
hipStream_t stream)
- The function launches rocshmem_alltoallmem_kernel which calls
device-side alltoall<char> workgroup collective through default context.
- Uses dynamic block size determination via occupancy API.
- Implemented for all backends.
* Fix incorrect sync buffer size allocation for alltoall in GDA and IPC backends
When allocating memory for alltoall_pSync_pool in setup_teams() and
teams_init() functions, the code incorrectly used ROCSHMEM_BCAST_SYNC_SIZE
instead of ROCSHMEM_ALLTOALL_SYNC_SIZE.
* Add functional test for team_alltoallmem_on_stream
This commit adds a new functional test to verify the correctness of
the host-side rocshmem_team_alltoallmem_on_stream API.
* Add documentation for rocshmem_alltoallmem_on_stream
This commit adds API documentation for the host-side
rocshmem_alltoallmem_on_stream function in the collective routines
section. The documentation includes:
* add relaxed_ordering option
add an environment variable that allows to control setting the
IBV_ACCESS_RELAXED_ORDERING flag when registering memory with the
ibv_reg_mr* functions.
* missed a spot
* Add `ROCSHMEM_CTX_INVALID` for invalid context handling
- Define `ROCSHMEM_CTX_INVALID` as {nullptr, nullptr}
- Add == and != operators to rocshmem_ctx_t
- Use `ROCSHMEM_CTX_INVALID` on failed context creation
- Skip ctx destroy if context is invalid
* Update docs for context create and destroy APIs usage and behavior
* Added the ability to compile for Local gpu by environment variable
* adding gfx950 on default only on rocm 7.0 and above
* Updated docs
* removed xnack+ on specific gfx targets

* relax MPI dependency from code
This commit (series) removes the strict dependency on MPI in code base.
rocSHMEM will still be compiled with MPI, but the goal is to make the
code work even if MPI_Init_thread has not been invoked, at least for
certain, well-defined scenarios. Hence, the goal is not remove any
mentioning of MPI from rocSHMEM, but to ensure correct execution of the
ipc conduit even if the library has been initialized using other means.
Details:
- add non-MPI version of remote_heap and WindowInfo classes
- host interfaces work on WindowInfoMPI, they will not work with the
non-MPI code path. Since it is unclear whether we plan to support the
host interfaces at all, this is probably not a major limitation.
* update symmetric_heap structures and backend
* first cut on initialization
and enabling non-MPI initialization of the IPCBackend
* add non-MPI hostInterface methods
at the moment, only barrier_all and sync_all are explicitely supported.
* add non-mpi version of ipc_policy
and a number of smaller fixes required in other files.
A small init/finalize test already passes now with the branch.
* add non-mpi team_split_strided code
* minor fixes for non-MPI use-case
* disable symmetric-heap-window-ionfo test
disable this test for now just to make the compilation pass. Will have
to rework it.
* make no-mpi great again
after rebasing on top of the MPI singleton changes.
* enable running functional tests with uuid init
to run the functional tests using rocshmem_init_attr and the uuid
mechanism requires
a) a PMIx installation on the system
b) setting the environment variable ROCSHMEM_TEST_UUID=1
* fix multi-team creation bug
fix a bug occuring when creating many teams, which was the result of
incorrectly applying two indices in our own implementation of Allreduce.
* make unit tests pass again
* reverse offload was impacted by code change
fix the RO conduit to cope wioth the non-MPI path introduced for the IPC
conduit.
* update to cmake logic to find pmix
* Update src/memory/window_info.hpp
Co-authored-by: Yiltan <ytemucin@amd.com>
* Update CMakeLists.txt
Co-authored-by: Yiltan <ytemucin@amd.com>
* document ROCSHMEM_UNIQUEID_NO_MPI
* rename env. variable to UNIQUEID_WITH_MPI
* update host.cpp to use USE_HDP_FLUSH macro
instead of the deprecated USE_COHERENT_HEAP.
* add note for running example with RO conduit
add a note clarifying that running init_attr_test from the example
directory requires setting an additional environment variable with the
RO conduit.
* Find PMIx in more cases, only apply pmix build options to the test that
needs it, if OMPI_COMM_WORLD_LOCA_RANK is not setenv, abort
