Mojo function

shmem_init

shmem_init()

A collective operation that allocates and initializes the resources used by the SHMEM library.

shmem_init allocates and initializes resources used by the SHMEM library. It is a collective operation that all PEs must call before any other SHMEM routine may be called, except shmem_query_initialized which checks the current initialized state of the library. In the SHMEM program which it initialized, each call to shmem_init must be matched with a corresponding call to shmem_finalize.

The shmem_init and shmem_init_thread initialization routines may be called multiple times within an SHMEM program. A corresponding call to shmem_finalize must be made for each call to an SHMEM initialization routine. The SHMEM library must not be finalized until after the last call to shmem_finalize and may be re-initialized with a subsequent call to an initialization routine.

Raises:

If SHMEM initialization fails.
