Sandia OpenSHMEM v1.5.2rc1

The Sandia OpenSHMEM development team is pleased to announce SOS v1.5.2, release candidate 1. Below are some of the changes included in this release:

• Added support for the CXI libfabric provider, enabling SOS on the Slingshot interconnect. Setup instructions are on SOS's Github wiki.
• Added support for shmem_team_ptr routine.
• Added support for negatives strides in the OpenSHMEM teams APIs.
• Added checks for incorrect buffer overlap when error-checking is enabled.
• Added a configure option to enable deprecated tests, --enable-deprecated-tests, which is disabled by default.
• Added a configure option to enable libfabric manual progress, --enable-ofi-manual-progress, which is disabled by default.
• Added experimental support for a hint to shmem_malloc_with_hints, SHMEMX_MALLOC_NO_BARRIER, which removes the barrier at exit from the routine. Users must synchronize appropriately after such an operation.
• Initialized the OFI tx/rx capabilities appropriately to limit what is enabled by providers. This resolves an issue with the Omni-Path Express (opx) provider.
• Patched the symmetric data segment initialization to better support MacOS.
