Arguments

ctx     The context on which to perform the operation. When this argument is
        not provided, the operation is performed on SHMEM_CTX_DEFAULT.
fetch   Local address of data object to be updated. The type of fetch should
        match that implied in the SYNOPSIS section.
dest    Symmetric address of the destination data object. The type of dest
        should match that implied in the SYNOPSIS section.
pe      An integer that indicates the PE number on which dest is to be
        updated.  When using Fortran, it must be a default integer value.

Description

The nonblocking shmem_atomic_fetch_inc_nbi routines perform an atomic
fetch-and-increment operation. This routine returns after initiating the
operation. The operation is considered complete after a subsequent call to
shmem_quiet. At the completion of shmem_quiet, dest on PE pe has been increased
by one and the previous contents of dest fetched into the fetch local data
object.

Return Values

None.

Notes

None.
