/*

* These routines copy contiguous data from a local object to an object on the destination 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.
