v1.4.0 RC2 Pre-release
Pre-release

Features:

  • Improved support for installation with latest ROCm
  • Improved support for latest rdma-core
  • Adding support for CUDA IPC for intra-node GPU
  • Added support for CUDA memory allocation cache for mem-type detection
  • Added support for latest Mellanox devices
  • Added support for Nvidia GPU managed memory
  • Added support for multiple connections between the same pair of workers
  • Added support large worker address for client/server connection establishment
    and INADDR_ANY
  • Added support for bitwise atomics operations

Bugfixes:

  • Performance fixes for rendezvous protocol
  • Memory hook fixes
  • Clang support fixes
  • Self tl multi-rail fix
  • Thread safety fixes in IB/RDMA transport
  • Compilation fixes with upstream rdma-core
  • Multiple minor bugfixes (full list on github)
  • Segfault fix for a code generated by armclang compiler
  • UCP memory-domain index fix for zero-copy active messages

Tested configurations:

  • InfiniBand: MLNX_OFED 4.2-4.4, distribution inbox drivers, rdma-core
  • CUDA: gdrcopy 1.2, cuda 9.1.85
  • XPMEM: 2.6.2
  • KNEM: 1.1.2
  • Multiple bugfixes (full list on github)

Known issues:

  • #2919 - Segfault in CUDA support when KNEM not present and CMA is active
    intra-node RMA transpor. As a workaround user can disable CMA support at
    compile time: --disable-cma. Alternatively user can remove CMA from UCX_TLS
    list, for example: UCX_TLS=mm,rc,cuda_copy,cuda_ipc,gdr_copy.

v1.2.2

Main:

  • Support including UCX API headers from C++ code
  • UD transport to handle unicast flood on RoCE fabric
  • Compilation fixes for gcc 7.1.1, clang 3.6, clang 5

Details:

  • When UD transport is used with RoCE, packets intended for other peers may
    arrive on different adapters (as a result of unicast flooding).
  • This change adds packet filtering based on destination GIDs. Now the packet
    is silently dropped, if its destination GID does not match the local GID.
  • Added a new device ID for InfiniBand HCA
  • [packaging] Move examples/ and perftest/ into doc
  • [packaging] Update spec to work on old distros while complaint with Fedora
    guidelines
  • [cleanup] Removed unused ptmalloc version (2.83)
  • [cleanup] Fixup license headers
