The Sandia OpenSHMEM development team is pleased to announce SOS v1.4.5. Below are some of the changes included in this release:

  • Added a complete OpenSHMEM teams API to the shmemx interfaces.
  • Added the OpenSHMEM wait/test vector API to the shmemx interfaces.
  • Added support for shared memory atomic operations with the appropriate acquire/release memory ordering where required. This feature requires the --enable-shr-transport build flag.
  • Improved experimental support for the RXM/Verbs provider stack with libfabric 1.8 and newer.
  • Updated SOS to use the new OFI memory registration mode flags instead of the deprecated FI_MR_SCALABLE/FI_MR_BASIC modes.
  • Updated the wait/test any/all/some "status" array semantics to reflect recent changes to the OpenSHMEM specification.
  • Added a memory sync before returning from barriers to ensure shared memory updates and remote updates cached in the NIC are visible in memory.
  • Updated the utility atomics (spinlocks and counters) to use __atomic built-in functions rather than the deprecated __sync builtins.
  • Removed redundant shmem_barrier_all from the GUPS example application.
  • Moved unit tests derived from OpenSHMEM specification examples to the test/spec-example directory.
