Motivation

multi-transport support with dual P2P and RDMA && enhance bnxt provider

Technical Details

1. Dual Data Path Architecture (P2P + RDMA)

Introduced p2pPeerPtrs alongside existing peerPtrs to maintain separate data paths:

• p2pPeerPtrs: Always established for same-node peers

  • Self: Contains localPtr
  • Same-node peers: P2P accessible pointers
  • Different-node peers: nullptr
  • Independent of transport type selection

• peerPtrs: Transport-specific addressing

  • RDMA transport: Remote virtual addresses
  • P2P/SDMA transport: P2P pointers

2. More SHMEM Device P2P Pointer APIs

uint64_t ShmemPtrP2p(const uint64_t destPtr, int destPe, const int myPe);
uint64_t ShmemPtrP2p(const uint64_t destPtr, int destPe);
uint64_t ShmemPtrP2p(const SymmMemObjPtr& memObjPtr, size_t offset, int destPe);

3. BNXT RDMA Provider Fixes

• Added MORI_BNXT_ENABLE_UDP_SPORT environment variable for UDP sport configuration
• Fix cleanup bugs of double registration/unregistration of shared UAR when using default DB region

Test Result

• UT test_p2p_direct_access passed on Thor2 platform and AINIC platform for 3 shmem mode
• EP16 benchmark passed on AINIC platform for 3 shmem mode
