* Add functional test for rocshmem_putmem_on_stream
* Add host-side rocshmem_putmem_signal_on_stream API
Enables asynchronous putmem operations with signaling on HIP streams.
The implementation includes:
- Kernel wrapper rocshmem_putmem_signal_kernel
- Host interface putmem_signal_on_stream method
- Context layer support across all backends (IPC, GDA, RO)
- Public API
Function signature:
void rocshmem_putmem_signal_on_stream(void *dest, const void *source,
size_t bytes, uint64_t *sig_addr,
uint64_t signal, int sig_op,
int pe, hipStream_t stream);
* Add functional test for rocshmem_putmem_signal_on_stream
* Add host-side rocshmem_signal_wait_until_on_stream API
Enables asynchronous signal wait operations on HIP streams.
The implementation includes:
- Kernel wrapper rocshmem_signal_wait_until_kernel
- Host interface signal_wait_until_on_stream method
- Context layer support across all backends (IPC, GDA, RO)
- Native uint64_t support in wait_until API (generated from P2P_SYNC.py)
Function signature:
void rocshmem_signal_wait_until_on_stream(uint64_t *sig_addr, int cmp,
uint64_t cmp_value,
hipStream_t stream);

* Add functional test for rocshmem_signal_wait_until_on_stream
* Add documentation for stream API functions
This commit adds API documentation for the following host-side
stream functions:
- rocshmem_barrier_all_on_stream (collective routines)
- rocshmem_broadcastmem_on_stream (collective routines)
- 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.

* 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
[ROCm/rocshmem commit: d0c8380650]
* 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:
[ROCm/rocshmem commit: 5577feb70d]
* 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
[ROCm/rocshmem commit: 955c22aeed]
* Refactor `Barrier_all` and `Sync_all` to use default context
- Removed context-specific implementations of barrier_all and sync_all
- Added barrier_all and sync_all to the default context implementation
- Updated functional tests to use the default context for barrier_all and sync_all
* Update `Barrier_all` and `Sync_all` API usage in documentation
* Update `CHANGELOG`
