The new routine transfers the data asynchronously from the source PE to all
PEs in the OpenSHMEM job. The routine returns immediately. The source and
target buffers are reusable only after the completion of the routine.
After the data is transferred to the target buffers, the counter object
is updated atomically. The counter object can be read either using atomic
operations such as shmem_atomic_fetch or can use point-to-point synchronization
routines such as shmem_wait_until and shmem_test.

/*
|
|
* The nonblocking put routines provide a method for copying data from a contiguous local data
|
|
* object to a data object on a specified PE.
|
|
* These routines transfer nelems elements of the data object at address source on the calling
|
|
* PE, to the data object at address target on the remote PE pe. These routines start the
|
|
* remote transfer and may return before the data is delivered to the remote PE. The delivery
|
|
* of data into the data object on the destination PE from different put calls may occur in any
|
|
* order. Because of this, two successive put operations may deliver data out of order unless a
|
|
* call to shmem_fence() is introduced between the two calls.
|
|
* The routines return after posting the operation. The operation is considered complete after a
|
|
* subsequent call to shmem_quiet. At the completion of shmem_quiet, the data has been copied
|
|
* into the dest array on the destination PE.
