CALL SHMEMX_THREAD_QUIET

Description

The shmemx_thread_quiet function is the thread-specific version of
the shmem_quiet routine. It allows an individual thread to wait for
completion of puts and non-blocking gets it previously issued. All put
or non-blocking get operations issued prior to the call to
shmemx_thread_quiet are guaranteed to be visible to all other
processes no later than any subsequent memory load or store, remote put
or get, AMO, or synchronization operations that follow the call to
shmemx_thread_quiet.

If this routine encounters an error, it will print an error message and
abort.

Notes

Use the shmemx_thread_quiet function to allow an individual thread
to wait for completion of the puts and non-blocking gets it previously
issued.

The shmemx_thread_quiet function is most useful as a way of
ensuring ordering of delivery of several put operations. For example,
you might use shmemx_thread_quiet to await delivery of a block of
data before issuing another put that sets a completion flag on another
thread.

The shmemx_thread_quiet function is not needed if shmem_barrier(3),
shmem_barrier_all(3), or shmem_quiet(3) are called. The barrier
routines all wait for the completion of outstanding remote writes
(puts) of all threads. It is the programmer's responsibility to ensure
overall thread safety when using the above APIs.
