[petsc-dev] Release Announcement for Intel® SHMEM v1.1.0

[Rahman, Md]

Hello OpenSHMEM community members,
The Intel OpenSHMEM team is thrilled to announce the second open-source release of Intel® SHMEM library, v1.1.0. Intel SHMEM is a C++ software library that enables applications to invoke GPU-initiated OpenSHMEM communication APIs within device kernels implemented in SYCL. It supports Intel HPC/AI-focused GPUs, beginning with the Intel® Data Center GPU Max Series. Below is a summarized list of features and enhancements that are introduced in Intel SHMEM v1.1.0.

  *   Support for OpenSHMEM 1.5 teams and team-based collective operations
  *   Device and host API support for strided RMA operations - ibput and ibget, from OpenSHMEM 1.6
  *   Device and host API support for non-blocking atomic operations
  *   Device and host API support for size-based RMA and signaling operations
  *   Device and host API support for all/any/some versions of point-to-point synchronization operations
  *   Device and host API support for signal set, add, and wait-until operations
  *   Fixed implementation of `ishmem_free`
  *   Compatible with Sandia OpenSHMEM (SOS) v1.5.3rc1<https://urldefense.us/v3/__https://github.com/Sandia-OpenSHMEM/SOS/releases__;!!G_uCfscf7eWS!bR9foQm-LsWVthfVnJM7MUYUTHl-wzqzHAErJZMNoShTK6ujH8YspxVCs4hCepSQQBdE782qACaR5l_pXmu6-lc$ > and newer releases
