* Add functional test for barrier_all_on_stream
* Add rocshmem_barrier_all_on_stream support for GDA and RO backends
Implements rocshmem_barrier_all_on_stream operation for
GPU Direct Access and Reverse Offload backends.
Previously, rocshmem_barrier_all_on_stream was only supported for IPC backend.
* Add functional test for rocshmem_broadcastmem_on_stream
* Add host-side rocshmem_broadcastmem_on_stream API
Implement stream-based broadcast collective operation
- Add rocshmem_broadcastmem_on_stream host API and kernel implementation
- Add functional test TeamBroadcastmemOnStreamTester with multi-stream
support and correctness verification
- Use per-workgroup contexts to avoid contention across parallel streams
API:
rocshmem_broadcastmem_on_stream(team, dest, source, nelems, pe_root, stream)
* Add functional test for rocshmem_getmem_on_stream
* Add host-side rocshmem_getmem_on_stream API
Implement stream-based point-to-point RMA get operation
- Add rocshmem_getmem_on_stream host API and kernel implementation
- Support for asynchronous getmem operations on HIP streams
- Add backend support for GDA, RO, and IPC contexts
- Use work-group collective getmem for efficient memory transfer
API:
rocshmem_getmem_on_stream(dest, source, nelems, pe, stream)
(AI Assist)
* Add host-side rocshmem_putmem_on_stream API
- Add rocshmem_putmem_on_stream for asynchronous remote writes
- Support for concurrent RMA operations on HIP streams
- Add backend support for GDA, RO, and IPC contexts
- Use work-group device collective operation
API:
rocshmem_putmem_on_stream(dest, source, bytes, pe, stream)
(AI Assist)
* 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);
(AI Assist)
* 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.
(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
