* Implement `rocshmem_ptr` in IPC conduit
* tests: add functional test for `rocshmem_ptr`
- Add safety check for pointer access and condition check before printing results for `rocshmem_ptr` test
- Use `rocshmem_put` to store `rocshmem_ptr` availability for data validation
* 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

* 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

- Added functional tests to cover all `sync` APIs
* update naming convention for context-based `barrier` APIs
* Fix deadlock in `rocshmem_ctx_wg_barrier_all` API in IPC conduit by adding per-context pSync buffers and context IDs
- Added separate pSync buffers for each device context
- Resolved deadlock when invoking barrier API (`rocshmem_ctx_wg_barrier_all`) concurrently from multiple contexts
* Update barrier_all functional tests for multi-context support
* Add thread, wavefront, and workgroup-level barrier_all APIs in IPC and RO conduits
- Implemented barrier_all APIs at thread, wavefront, and workgroup granularity
- Added support in both IPC and RO conduits

- Implemented sync_all APIs for thread, wavefront, and workgroup scopes
- Added support into both IPC and RO conduits
- Added functional tests to cover all `sync_all` APIs
* Allocate default context buffers and initialize queue for management
- Allocated the status flag, g return, and atomic return buffers for
the default context.
- Initialized `AtomicWFQueueProxy` instances to manage these buffers
efficiently for concurrent access.
* Update `BlockHandle` with default context buffers
* Add default context flag and update buffer retrieval functions
- Added a flag to distinguish the default context from other contexts.
- Modified return buffer functionns and `get_status_flag` function to accommodate
the default context
* Add default context primitive tests
- get, put, get_nbi, put_nbi, g, and p APIs.
* add team-barrier implementation
add a team-barrier API and implementation in the IPC and RO conduit.
Clean up some of the logic in the RO Conduit to distinguish between
sync, sync_all, barrier, and barrier_all.
* add team_barrier_tests to functional tests
* Update primitive tests for multi-workgroup support
* Update workgroup primitive tests for multi-workgroup support
* Update workfront primitive tests for multi-workgroup support
* Update team based primitive tests for multi-workgroup support
* Update RMA functional tests to capture timing after quiet call
- Modified RMA functional tests to record the time after a `quiet` call in thread, wavefront, and workgroup RMA calls.
* Improve error handling and memory management
- Replaced `cout` with `cerr` for improved error reporting.
- Ensured all allocated memory is freed when `rocshmem_malloc` fails.
* Update start time in primitive tests and latency calculations
- Modified primitive tests to capture the earliest start time.
