The Sandia OpenSHMEM development team is pleased to announce SOS v1.4.2. Below are some of the changes included in this release:

  • Improved performance when using OFI thread completion model, by releasing the context lock when blocked in quiet/fence operations.
  • Added support for using MPI as the process manager, via --enable-pmi-mpi.
  • Added option to flush stdout/stderr during barrier operations, enabled via SHMEM_BARRIERS_FLUSH environment variable.
  • Added PE affinity information to debugging output, enabled via SHMEM_DEBUG environment variable.
  • Fixed issue with SHMEM_OFI_PROVIDER environment variable being unrecognized.
  • Added experimental performance counters API extension (see shmemx.h)
  • Added --enable-ofi-mr={basic,scalable,rma-event} and removed --with-ofi-mr, --disable-mr-scalable, and --enable-mr-rma-event.
  • Renamed --with-total-data-ordering configuration flag to --enable-total-data-ordering.
  • Added multithreaded lock unit test to demonstrate the use of hierarchical locking to enable multithreaded usage of OpenSHMEM locks.
  • Updated perf. suite tests to improve bandwidth reporting and improve coverage over atomic operations.
  • Updated manual progress to automatically enable completion polling.
  • Updated target counter binding in OFI to comply with libfabric requirements.
  • Fixed invalid locking in context destroy debug message when bounce buffering is not enabled on the context.
  • Simplified the OFI random STX allocator.
