From 3b429e780606981b63d21b7da76bab0f153127c9 Mon Sep 17 00:00:00 2001 From: jhchouuu Date: Fri, 8 May 2026 16:35:09 +0800 Subject: [PATCH 01/15] feat(shmem): add MORI_MULTITHREAD_SUPPORT for single-process multi-thread (SPMT) - Add MORI_MULTITHREAD_SUPPORT cmake option (default OFF) - ShmemStatesSingleton::GetInstance() returns per-GPU slot via hipGetDevice() using std::array for stable addresses and lock-free reads - Embed GpuStates and ModuleStates as values in ShmemStates (no heap alloc) - Remove file-scope globals: s_hostGpuStatesCopy, s_shmemModule, s_deviceGpuStatesAddr, s_barrierFunc - All init/finalize functions take explicit ShmemStates* (thread-safe) - ShmemFinalize resets status to New to allow re-init on same GPU - PID allgather in CollectHostNames for same-process P2P detection - Skip hipIpcOpenMemHandle for same-process peers (use direct pointer) - Python: per-GPU JIT module loading with double-check locking - Python: GIL release on all blocking shmem APIs - mori_log: try/catch spdlog race on concurrent logger registration - Add tests/python/shmem/test_spmt.py (world_size 2/4/8) Co-Authored-By: Claude Sonnet 4.6 --- CMakeLists.txt | 3 + examples/CMakeLists.txt | 7 + examples/shmem/multithread_multi_gpu.cpp | 266 +++++++++++++++++++ include/mori/application/context/context.hpp | 14 +- include/mori/shmem/internal.hpp | 91 ++++--- include/mori/utils/mori_log.hpp | 11 +- python/mori/shmem/api.py | 45 +++- setup.py | 2 + src/application/context/context.cpp | 57 ++-- src/application/memory/symmetric_memory.cpp | 11 +- src/pybind/pybind_shmem.cpp | 18 +- src/shmem/CMakeLists.txt | 5 + src/shmem/init.cpp | 95 ++++--- src/shmem/runtime.cpp | 64 ++--- tests/python/shmem/test_spmt.py | 135 ++++++++++ 15 files changed, 681 insertions(+), 143 deletions(-) create mode 100644 examples/shmem/multithread_multi_gpu.cpp create mode 100644 tests/python/shmem/test_spmt.py diff --git a/CMakeLists.txt b/CMakeLists.txt index 059807e8..890bd89a 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -40,6 +40,8 @@ option(ENABLE_PROFILER "Enable kernel profiling" OFF) option(ENABLE_DEBUG_PRINTF "Enable debug printf in device kernels" OFF) option(ENABLE_STANDARD_MOE_ADAPT "Enable standard moe adapt" OFF) option(BUILD_OPS_DEVICE "AOT compile EP kernels to .hsaco(requires hipcc)" OFF) +option(MORI_MULTITHREAD_SUPPORT + "Enable single-process multi-thread multi-GPU support in mori_shmem" OFF) # --------------------------------------------------------------------------- # Host NIC: all vendor-specific dv libraries (mlx5, bnxt_re, ionic) are loaded @@ -158,6 +160,7 @@ add_library(mori_logging INTERFACE) target_include_directories(mori_logging INTERFACE include) target_link_libraries(mori_logging INTERFACE spdlog::spdlog_header_only) + if(ENABLE_PROFILER) find_package( Python3 diff --git a/examples/CMakeLists.txt b/examples/CMakeLists.txt index f29ed4d5..fbe47924 100644 --- a/examples/CMakeLists.txt +++ b/examples/CMakeLists.txt @@ -125,6 +125,13 @@ target_link_libraries(intra_node_benchmark mori_collective MPI::MPI_CXX target_include_directories(intra_node_benchmark PRIVATE ${CMAKE_SOURCE_DIR}/include) +# Multi-thread multi-GPU exploration (requires MORI_MULTITHREAD_SUPPORT) +if(MORI_MULTITHREAD_SUPPORT) + add_shmem_example(multithread_multi_gpu SOURCES shmem/multithread_multi_gpu.cpp) + target_compile_definitions(multithread_multi_gpu PRIVATE MORI_MULTITHREAD_SUPPORT) + target_link_libraries(multithread_multi_gpu stdc++fs) +endif() + # --- Application examples --- add_executable(context application/context.cpp) target_link_libraries(context mori_application hip::host hip::device) diff --git a/examples/shmem/multithread_multi_gpu.cpp b/examples/shmem/multithread_multi_gpu.cpp new file mode 100644 index 00000000..95fb5e57 --- /dev/null +++ b/examples/shmem/multithread_multi_gpu.cpp @@ -0,0 +1,266 @@ +// Copyright © Advanced Micro Devices, Inc.

All changes are gated by MORI_MULTITHREAD_SUPPORT; the macro-OFF and multi-process paths are byte-identical to before. Three structural caches that used hipModuleLoad-bound resources were process-global singletons. Under SPMT each thread is bound to its own device, so a singleton hands the wrong device's resources to other threads and the EP launches crash or silently use the wrong context: - KernelRegistry::GetImpl: was a static singleton holding loaded hipModule_t. Now std::array indexed by hipGetDevice(). In multi-process every process sees its single GPU as device 0 and collapses to slot[0] — equivalent to the old singleton. - pybind_xla_ffi_ops g_handle_cache: was process-global with one mutex. Under SPMT this would deadlock — thread A holds the mutex during EpDispatchCombineHandle's cross-PE Barrier(), thread B blocks waiting for the mutex and never reaches its own Barrier(). Replaced with per-GPU HandleCacheSlot (own mutex + map). - ShmemStatesSingleton rank→device map: XLA FFI handlers run on framework worker threads where hipGetDevice() does NOT match the rank's device. Added RegisterRankDevice/GetDeviceByRank, populated in InitializeBootStates from the user thread's device. FFI handlers (Instantiate + Impl) now look up the rank's device and hipSetDevice to it before any state access. python/mori/shmem/api.py:_ensure_shmem_module no longer imports torch to read the current device — that import broke JAX containers that ship without torch. Now uses ctypes hipGetDevice via the existing mori.jit.hip_driver helper, working uniformly for both torch and JAX. Adds tests/python/ops/test_dispatch_combine_jax_spmt.py: spawns one host thread per GPU in a single Python process, each thread runs ShmemInit + EpDispatchCombineOp dispatch+combine via XLA FFI. Verifies the full SPMT JAX path end-to-end. Per-thread shmem_finalize + clear_ep_handle_cache so the parametrized 2/4/8 GPU sizes can run in one pytest invocation.

The previous implementation iterated ALL per-GPU slots from any caller, so when thread 0 called clear_ep_handle_cache it ran ~EpDispatchCombineHandle on thread 1's, 2's, ... handles too. Each ~Handle calls ShmemFree on the buffers it allocated on its own GPU's symmetric heap, but the calling thread's hipDevice was still 0, so ShmemFree looked up those addresses in GPU 0's HeapVAManager and reported "address not found" hundreds of times before the test process eventually aborted with SIGABRT during teardown. Fix: only clear the slot returned by GetHandleCacheSlot() (the calling thread's slot under SPMT, the global slot in single-GPU mode). Each SPMT thread is responsible for clearing its own cache as part of its shmem_finalize sequence — same pattern as ShmemStatesSingleton. Also: in tests/python/ops/test_dispatch_combine_jax_spmt.py add the gc.collect() between cache clear and shmem_finalize (mirrors mori.jax.shmem_finalize). Do NOT call jax.clear_caches() — it is process-global and races across SPMT threads. After this fix the SPMT JAX EP test exits 0 cleanly with zero HeapVAManager errors, across 5 consecutive 2/4/8 GPU runs. Multi-process JAX EP regression unaffected.

Centralize kMaxGpusPerNode in mori/utils/limits.hpp. Previously the constant was duplicated in three places (internal.hpp, launch.cpp, pybind_xla_ffi_ops.cpp) and bumping it for >8-GPU nodes (e.g. future MI400) would have required editing all three. Now a single inline constexpr that any TU can pull in cheaply. 2. Drop dead ShmemStatesSingleton::mutex_ field. The comment claimed "we still take a brief lock the first time to guard concurrent ShmemInit", but no code actually locks it. SPMT's contract is one thread per GPU, so each slot is accessed serially by its owner thread; cross-thread synchronization is only needed for the rank → device map below, which has its own mutex. 3. Drop dead ShmemStatesStatus::Finalized. ShmemFinalize resets to New (so the slot can be reused for re-init), so the Finalized state was never actually set, which made the check `if (status == Finalized)` in ShmemInit dead code. Removed both. 4. RAII ScopedDevice guard for XLA FFI handlers. The previous code called hipSetDevice(rank_dev) directly, leaving XLA's worker thread bound to a different device than what XLA had set on entry — a subtle violation of the convention that XLA owns its worker thread state. ScopedDevice restores the saved device on scope exit so the change is local to the FFI handler call. 5. Also: drop spurious (void)hipGetLastError() calls in three lookups. They were silently swallowing real errors from prior unchecked HIP calls. hipGetDevice / hipSetDevice return their own status; sticky errors only surface on next hipDeviceSynchronize / kernel launch. 6. Test doc fix: clarify why _build_config passes gpu_per_node == world_size (single-node SPMT, EP handle requires IsPowerOf2(gpuPerNode) && worldSize % gpuPerNode == 0). I briefly tried to "fix" this to use the physical GPU count and tripped the assertion — kept the original behavior with explanatory comments.

That removal was over-aggressive. The Finalized state value is documented intent (a slot can be in three logical phases: never-init / live / torn-down) and someone might want terminal-finalize semantics later — for example, to print a clearer diagnostic when a finalized slot is touched again, or to forbid re-init in a stricter deployment. Restore both the enum value and the corresponding check in CheckStatusValid(). Leave ShmemFinalize() as-is (resets to New) so SPMT test suites that init/finalize multiple times keep working; if/when finalize semantics need to flip, only the line in ShmemFinalize() needs to change.

False-pass behavior: when the cross-PE collective-permute kernel produces wrong data, the example still marks the result as PASS (line 194: `result.permute_pass = true; // expected under static binary SPMT`). A "regression test" that always passes regardless of correctness is worse than no test — it gives false confidence. 2. The kernel is documented to be incorrect: the example's own header comments admit that under a statically-compiled HIP binary, globalGpuStates is a single device symbol shared across all SPMT threads, so the device-side kernel result "may not be correct under SPMT". The collective-permute kernel exists but does nothing meaningful as a regression check. Coverage is now provided by two Python tests: - tests/python/shmem/test_spmt.py — shmem control plane (init/finalize/malloc/barrier) with real assertions - tests/python/ops/test_dispatch_combine_jax_spmt.py — full EP dispatch+combine round-trip with data verification Both Python tests use JIT-loaded modules, so each GPU has its own globalGpuStates and the kernels actually exercise SPMT correctly.

No behavior change for happy-path callers; pure robustness/cleanup. 1. python/mori/shmem/api.py: _current_hip_device() now sets explicit argtypes/restype on hip.hipGetDevice. Without these ctypes assumes int args + int return, which happens to be right on x86_64 Linux but is not portable. Be explicit so future ABI shifts don't silently corrupt the device id we read. 2. src/pybind/pybind_xla_ffi_ops.cpp: EpDispatchCombineInstantiate was decoding the packed ep_config twice — once to extract `rank` for SPMT device routing, and once on cache miss to construct the handle. Decode once and reuse. Saves a small amount of work on the cache-miss path; mostly a readability win. 3. include/mori/utils/mori_log.hpp: after the try/catch around spdlog::stdout_color_mt, fall back to spdlog::get() — but that call can in principle return null (e.g. if the registry was dropped between the throw and our second lookup).

That's enough to catch deadlocks and gross crashes, but it would silently pass even if dispatch routed tokens to the wrong rank or combine produced garbage. Port the dispatch/combine validation from test_dispatch_combine_jax.py: - _validate_dispatch: decode (sender_pe, local_tok_id) from src_token_pos, look up the original input via inputs_list[pe * inp_tok_per_rank + local_id], and check it matches the dispatched output. Also check no two received tokens share the same src_pos (no double-delivery). - _validate_combine: each input token is dispatched to `unique_pes` distinct PEs; combine sums the unique_pes copies, so combined output should equal `input * unique_pes` (within bf16 atol/rtol). The multi-process test does cross-rank all-gather via shard_map + jax.lax.all_gather. SPMT can't use that (no jax.distributed). Instead, every rank generates inputs deterministically from PRNGKey(BASE_SEED + rank), so each thread can locally reconstruct every other rank's inputs by re-seeding — no cross-thread comm needed. Also add the env-var bypass set by the multi-process test: MORI_SHMEM_HEAP_SIZE=16G (4G default is tight for 8-GPU EP) XLA_FLAGS: --xla_gpu_autotune_level=0 (skip slow first-JIT autotune) --xla_gpu_enable_command_buffer= (disable HIP graph) --xla_gpu_enable_triton_gemm=false (avoid Triton-AMDGPU pass errs) Verified: 2/4/8 GPU all PASS with both "dispatch data verified" and "combine data verified" printed per thread; clean exit; no Triton noise.

Core changes: - anvil: key sdma_channels_ by (srcDeviceId, dstDeviceId) pair instead of dstDeviceId alone, preventing channel cross-contamination between GPUs in the same process. Add mutex for thread-safe map access during concurrent shmem_init from multiple SPMT threads. - symmetric_memory: for same-process peers (SPMT), exchange SDMA signal pointers via Allgather raw VA + hipDeviceEnablePeerAccess instead of hipIpcOpenMemHandle (which fails within the same process). Clear HIP sticky errors after hipDeviceEnablePeerAccess. On deregistration, close SDMA signal IPC handles for cross-process peers and free all SDMA GPU allocations (signalPtrs, expectSignalsPtr, peerSignalPtrs, deviceHandles_d). - launch: fix AsyncLL kernel launch sequence in C++ path (used by JAX FFI) to match the split kernel names actually defined in ep_async_ll.hip. The previous code referenced non-existent combined kernel names. - dispatch_combine: guard ~EpDispatchCombineHandle against use-after- finalize when XLA destroys cached FFI state after shmem_finalize. - jax/ops.py: add AsyncLL to get_dispatch_src_token_pos kernel type list. - tests: run each SPMT world_size in an isolated subprocess to ensure clean shmem lifecycle (AnvilLib singleton and KFD SDMA queues are not released by shmem_finalize). Add test_dispatch_combine_jax_spmt_sdma.py covering dispatch+combine E2E with data verification for world_size 2, 4, 8.
