Supported/Unsupported Features
The following tables indicate which APIs are supported in Intel® SHMEM as of
the 1.1.0 release.
The Intel® SHMEM development team strives to eventually support all OpenSHMEM
APIs.
Currently unsupported interfaces are targeted for implementation in future
releases of Intel® SHMEM.
