/*
|
|
* shmem_cswap performs an atomic conditional swap operation.
|
|
* The conditional swap routines write value to address target on PE pe, and return the previous
|
|
* contents of target. The replacement must occur only if cond is equal to target;
|
|
* otherwise target is left unchanged. In either case, the routine must return the initial value
|
|
* of target. The operation must be completed without the possibility of another process updating
|
|
* target between the time of the fetch and the update.
