DESCRIPTION
rms_prgsuspend() suspends all of the processes in a program. The RMS suspends a
parallel program by calling rms_prgsuspend() on each node that it is using.
rms_prgsuspend() requires administrator privileges. rms_prgresume() resumes all
of the processes in a program. The RMS resumes a parallel program by calling
rms_prgresume() on each node that it is using. rms_prgresume() requires
administrator privileges.
rms_prgsignal() sends a signal to all of the processes in a program. The RMS delivers
signals to a parallel program by calling rms_prgsignal() on each node that it is using.
The function is also used to confirm that all processes belonging to a program have
exited. rms_prgsignal() can be called by the owner of the program or a process with
administrator privileges.
RETURN VALUES
Upon successful completion, rms_prgsuspend(), rms_prgresume() and
rms_prgsignal() return 0. Otherwise, they return -1 and set errno to indicate the
