From e54d0b1291fdfd2e49efd41abc84a0c1742fe2eb Mon Sep 17 00:00:00 2001 From: Tej Kiran Date: Mon, 3 Aug 2026 14:47:57 -0500 Subject: [PATCH 001/132] feat(shmem): CPU proxy for IBGDA operations on Pensando AINIC Add proxy infrastructure for EP on AINIC where GPU-initiated IBGDA WQE posting doesn't work (NIC rejects GPU-written WQEs). The proxy approach: GPU writes command descriptors to a shared ring, CPU thread calls ibv_post_send, GPU polls per-slot status for completion. New files: - proxy_types.hpp: ProxyCmd, ProxyRing shared GPU+CPU types (128-byte aligned) - proxy_device_primitives.hpp: GPU __device__ functions (ProxyPostWrite, ProxyPostWriteInline, ProxyPostAtomic, ProxyQuiet) - proxy_thread.hpp/.cpp: CPU proxy thread (polls ring, ibv_post_send, ibv_poll_cq) - gpu_proxy_rdma_repro.cpp: standalone 2-node reproducer Modified: - internal.hpp: add useProxy + proxyRing to GpuStates - shmem_ibgda_kernels.hpp: add proxy path to ShmemPutMemNbi and ShmemQuietPsd Test results (MI350X + AINIC, loopback): - Level 1 (types): PASS - Level 2 (CPU proxy thread, 1000 ops): PASS, 2.3M ops/s - Level 3 (GPU proxy, 5000 ops with ring wrap): PASS, 107K ops/s, 9.4 us/op Refs: itej89/mori#2 Co-Authored-By: Claude --- .../rdma/proxy/proxy_device_primitives.hpp | 159 +++++++ .../transport/rdma/proxy/proxy_thread.hpp | 45 ++ .../core/transport/rdma/proxy/proxy_types.hpp | 54 +++ include/mori/shmem/internal.hpp | 4 + include/mori/shmem/shmem_ibgda_kernels.hpp | 24 + .../transport/rdma/proxy/proxy_thread.cpp | 154 +++++++ tests/cpp/proxy/test_proxy_gpu.cpp | 237 ++++++++++ tests/cpp/proxy/test_proxy_thread.cpp | 264 +++++++++++ tests/cpp/proxy/test_proxy_types.cpp | 122 +++++ tests/cpp/proxy/test_step1_compile.cpp | 21 + tests/cpp/proxy/test_step2_compile.cpp | 9 + tools/gpu_proxy_rdma_repro.cpp | 434 ++++++++++++++++++ 12 files changed, 1527 insertions(+) create mode 100644 include/mori/core/transport/rdma/proxy/proxy_device_primitives.hpp create mode 100644 include/mori/core/transport/rdma/proxy/proxy_thread.hpp create mode 100644 include/mori/core/transport/rdma/proxy/proxy_types.hpp create mode 100644 src/application/transport/rdma/proxy/proxy_thread.cpp create mode 100644 tests/cpp/proxy/test_proxy_gpu.cpp create mode 100644 tests/cpp/proxy/test_proxy_thread.cpp create mode 100644 tests/cpp/proxy/test_proxy_types.cpp create mode 100644 tests/cpp/proxy/test_step1_compile.cpp create mode 100644 tests/cpp/proxy/test_step2_compile.cpp create mode 100644 tools/gpu_proxy_rdma_repro.cpp diff --git a/include/mori/core/transport/rdma/proxy/proxy_device_primitives.hpp b/include/mori/core/transport/rdma/proxy/proxy_device_primitives.hpp new file mode 100644 index 000000000..b84fb0897 --- /dev/null +++ b/include/mori/core/transport/rdma/proxy/proxy_device_primitives.hpp @@ -0,0 +1,159 @@ +// Copyright © Advanced Micro Devices, Inc.

charset=UTF-8 Content-Transfer-Encoding: 8bit Wire the proxy infrastructure into the MORI build and runtime: - Add proxy paths to all 6 PSD SHMEM functions in shmem_ibgda_kernels.hpp: ShmemPutMemNbi, ShmemPutSizeImmNbi, ShmemPutMemNbiSignal, ShmemAtomicSizeNonFetch, ShmemAtomicTypeFetch, ShmemQuietPsd - Each function checks globalGpuStates->useProxy and redirects to ProxyPost* primitives, bypassing IBGDA WQE/doorbell/CQ entirely - Allocate ProxyRing in GpuStateInit when MORI_USE_IBGDA_PROXY=1 - Start/shutdown ProxyThread with QP handles from endpoint setup - Add proxy_thread.cpp to application CMakeLists.txt - Forward-declare ProxyThread in internal.hpp (avoids in HIP) - Add host-only guard to proxy_thread.hpp Env var: MORI_USE_IBGDA_PROXY=1 enables proxy mode for ionic AINIC. Default (unset or 0) uses native IBGDA — no behavior change.

The proxy thread needs these handles to call ibv_post_send/ibv_poll_cq. Set endpoint.ibvHandle.qp and .cq from the IonicQpContainer's ibv handles. Also add stderr debug prints to track proxy activation in shmem init. EP test status: proxy activates (32 QPs found, proxy thread started), GPU kernel takes proxy path (no IBGDA WQE posting, no GPU fault), but RDMA fails with remote access error (status=10) — this is a rail topology issue (MR registered on wrong PD/NIC), not a proxy issue. Next: fix rail-isolated topology routing (Task 4).

charset=UTF-8 Content-Transfer-Encoding: 8bit Two fixes that resolve the SIGSEGV in multiprocessing.spawn child processes: 1. Lazy CQ polling: only poll CQ after ops_posted > 0. Previously the thread called ibv_poll_cq immediately on start, before any QP transitions completed across all processes. 2. Use posix_memalign + hipHostRegister instead of hipHostMalloc. hipHostMallocCoherent corrupts GPU device state in child processes. posix_memalign + hipHostRegister(Mapped|Portable) achieves the same GPU accessibility without touching GPU device context at allocation. Result: EP test runs with proxy enabled — no SIGSEGV, all 8 GPU processes init successfully, proxy threads start, GPU kernel writes to proxy ring, CPU thread posts via ibv_post_send, CQE completions received. CQE errors (transport retry) are expected with single NIC due to rail-isolated routing — needs multi-NIC for full EP.

RDMA atomics return CQE success but don't modify remote memory 2. QP connections must use matching NIC on both sides (rail isolation) 3. Traffic class TC must be set on proxy QPs for AINIC routing Fixes applied: - Agreed-rail mapping: both sides use max(myLocalGpu, peerLocalGpu) so QP connections are always on the same NIC index - Proxy QP setup matches non-proxy: active MTU, SL, TC, max_rd_atomic=15, IBV_ACCESS_REMOTE_ATOMIC - Atomic internal buffer (ibuf) allocated and registered per proxy QP for atomic result DMA; atomics use ibuf's own lkey instead of perNic override - IBV_SEND_FENCE on atomics for write-before-atomic ordering - Emulate RDMA atomics via IBV_WR_SEND_WITH_IMM: sender posts inline [dst_addr, add_value] payload; receiver proxy DrainCq detects IBV_WC_RECV, reads payload, does CPU __atomic_fetch_add on GPU memory, re-posts recv WR - Pre-post 128 recv WRs per QP after RTS transition (Pensando rejects post_recv in RESET state) - Recv buffer info plumbed: IonicDeviceContext::proxyRecvInfo map → IBVerbsHandle::recvBuf/recvLkey/recvCount → ProxyQpHandle - NCCL_IB_DISABLE=1 required (NCCL also hits IBGDA doorbell issue) Status: EP dispatch/combine runs end-to-end, 127/128 tokens pass correctness. Token 0 fails due to CPU-GPU atomic coherency race when both intra-node (GPU atomic via P2P) and inter-node (CPU __atomic_fetch_add via proxy) write to the same signal counter.

Without this, the GPU reads stale L2 cache data while NIC has written fresh data to VRAM, corrupting dispatch metadata (expert indices). 2. PCIe read fence before signal counter atomic: RDMA_WRITE (data) and SEND_WITH_IMM (signal) take different paths to the receiver — data goes NIC→GPU VRAM via DMA, signal goes NIC→CPU recv buffer→proxy thread. A CPU read from GPU VRAM forces PCIe posted write ordering, ensuring the data DMA completes before the signal counter is incremented. Combined with clflush+sfence for CPU→GPU write visibility. Result: Node 1 fully passes (Dispatch + Combine). Node 0 dispatch passes with correct token counts. 126/128 tokens pass data correctness. 2 tokens (token 0 with duplicate PE routing) fail — likely an EP algorithm edge case, not a proxy issue.

PCIe does not order writes from different sources. The GPU sees the CPU-written signal before the NIC's data DMA completes, reads stale staging data, and gets garbage expert indices. Fix: convert PROXY_ATOMIC_FETCH_ADD to IBV_WR_RDMA_WRITE instead of IBV_WR_SEND_WITH_IMM. Both data and signal now go through the NIC, same PCIe initiator. IBV_SEND_FENCE on the same QP guarantees the data write completes before the signal write. No CPU writes to GPU VRAM, no hipSetDevice, no recv WRs needed. This is safe because there is zero contention on signal entries: each receiver GPU's chunkFlag/nodeRecvTokenNum is written by exactly one sender GPU (proxyPe = destNode * gpuPerNode + rank % gpuPerNode, blockFlagCounter is per-GPU with unique flagSlotIds via atomicAdd). Removes: SEND_WITH_IMM recv handling, hipSetDevice, recv WR posting, ProxyRecvInfo, IBVerbsHandle recv fields, proxy uncached heap hack. Net -120 lines.

With vLLM DeepSeek-V4 (61 MoE layers, ~31 shmem_malloc per layer = ~1900 calls), this meant ~15,000 barriers across 16 PEs, causing MORI SHMEM init to hang for 15+ minutes. Sub-allocations within the StaticHeap share the heap's MR — the per-NIC rkeys from sub-allocation registrations overwrote the heap's keys and were never used by the proxy thread (which reads perNicLkeys from the SymmMemManager, set only by the heap registration). Fix: gate per-NIC MR registration on heap_begin=true. Only the initial heap allocation does the 8-NIC barrier+Allgather dance. Sub-allocations skip it entirely.

Each GPU warp posts to the ring for its target NIC, eliminating cross-NIC atomic contention on gpu_head. Fix ProxyQuiet to only scan slots posted since the last quiet (tracked via proxyQuietHead[]) instead of scanning the entire 65536-slot ring. Each slot load is a PCIe round-trip (~1us), so scanning the full ring added ~65ms of overhead per fence. Dispatch RDMA BW: 9.15 → 31.56 GB/s (3.4x, gap to native IBGDA shrunk from 5.4x to 1.6x). Combine: 33.15 → 52.51 GB/s (exceeds MI300x native). EP test: 500 rounds, 0 failures.

Warp/Block macros dispatched straight to IBGDA, bypassing the proxy. Introduce PROXY_DISPATCH_GUARD / PROXY_DISPATCH_GUARD_RET macros that expand to the proxy check when MORI_PROXY_ENABLED is set, and to nothing otherwise.

Proxy fields (rings, quietHead, numProxyRings, numNics, localGpuIdx) are in GpuStates and travel via the single existing GpuStates hipMemcpy. This eliminates the two-symbol contention issue that caused uneven per-rank bandwidth under NIC load. Also simplify ShmemQuietThread() no-arg to use numProxyRings > 0 check instead of PE loop (single device memory read vs 16).

Since send_cq == recv_cq and the WR is SIGNALED, its completion landed in DrainCq as IBV_WC_SEND with wr_id=0, which unconditionally marked ring slot 0 as COMPLETED — corrupting whatever command the GPU had pending in that slot. Fix: set wr_id = PROXY_WRID_INTERNAL (high-bit sentinel) on the reply WR and skip any CQE with that sentinel at the top of DrainCq. Co-Authored-By: Claude * fix: log error when internal reply SEND fails Don't silently drop failed reply completions — log the status so operators can diagnose fetch-atomic hangs. Co-Authored-By: Claude * docs: clarify why bit 63 is collision-free for PROXY_WRID_INTERNAL Co-Authored-By: Claude --------- Co-authored-by: Tej Kiran Co-authored-by: Claude --- include/mori/core/transport/rdma/proxy/proxy_types.hpp | 3 +++ src/application/transport/rdma/proxy/proxy_thread.cpp | 8 ++++++++ 2 files changed, 11 insertions(+) diff --git a/include/mori/core/transport/rdma/proxy/proxy_types.hpp b/include/mori/core/transport/rdma/proxy/proxy_types.hpp index e6d3bcaa8..41026686b 100644 --- a/include/mori/core/transport/rdma/proxy/proxy_types.hpp +++ b/include/mori/core/transport/rdma/proxy/proxy_types.hpp @@ -83,6 +83,9 @@ struct alignas(128) ProxyCmd { static_assert(sizeof(ProxyCmd) == 128, "ProxyCmd must be 128 bytes"); +// Bit 63 sentinel — slot wr_ids are uint32_t zero-extended, so bit 63 is always free. +static constexpr uint64_t PROXY_WRID_INTERNAL = 1ull << 63; + static constexpr uint32_t PROXY_RING_SIZE = 65536; static constexpr uint32_t PROXY_RING_MASK = PROXY_RING_SIZE - 1; static constexpr int PROXY_MAX_NICS = 8; diff --git a/src/application/transport/rdma/proxy/proxy_thread.cpp b/src/application/transport/rdma/proxy/proxy_thread.cpp index aae5440cf..52a9e5361 100644 --- a/src/application/transport/rdma/proxy/proxy_thread.cpp +++ b/src/application/transport/rdma/proxy/proxy_thread.cpp @@ -93,6 +93,13 @@ void ProxyThread::DrainCq(ProxyQpHandle& qph) { int n; while ((n = ibv_poll_cq(qph.cq, 64, wc)) > 0) { for (int i = 0; i < n; i++) { + if (wc[i].wr_id & PROXY_WRID_INTERNAL) { + if (wc[i].status != IBV_WC_SUCCESS) { + MORI_APP_ERROR("proxy: internal reply SEND failed status={} ({})", wc[i].status, + ibv_wc_status_str(wc[i].status)); + } + continue; + } if (wc[i].status != IBV_WC_SUCCESS) { if (wc[i].opcode & IBV_WC_RECV) { MORI_APP_ERROR("proxy: RECV CQE error status={} ({}) ibvQP={}", wc[i].status, @@ -158,6 +165,7 @@ void ProxyThread::DrainCq(ProxyQpHandle& qph) { rsge.addr = reinterpret_cast(&reply_buf.data[0]); rsge.length = 16; ibv_send_wr rwr{}, *rbad = nullptr; + rwr.wr_id = PROXY_WRID_INTERNAL; rwr.opcode = IBV_WR_SEND_WITH_IMM; rwr.imm_data = htonl(PROXY_IMM_ATOMIC_REPLY); rwr.send_flags = IBV_SEND_SIGNALED | IBV_SEND_INLINE;
