|
|
to this particular shmem_barrier_all() statement.

|
||
|
|
|

.SH DESCRIPTION
|
||
|
|
|
||
|
|
The shmem_barrier_all routine does not return until all other PEs have entered this routine
|
||
|
|
at the same point of the execution path.
|
||
|
|
.PP
|
||
|
|
Prior to synchronizing with other PEs, shmem_barrier_all ensures completion of all
|
||
|
|
previously issued local memory stores and remote memory updates issued via SHMEM
|
||
|
|
functions such as \fIshmem_put32\fP(3)\&.
