rms_prggetstats(3)
NAME
rms_prggetstats – Return resource usage information for a program
SYNOPSIS
cc [ flag ... ] file ... -lrmscall [ library ... ]
#include <rms/rmscall.h>
int rms_prggetstats(int id, prgstats_t *stats);
PARAMETERS
id Program identifier.
stats Pointer to a program statistics structure.
DESCRIPTION
rms_prggetstats() returns resource usage information for the processes of a parallel
program on the calling node. The RMS kernel module sums resource usage over the
processes in a program. The statistics returned by rms_prggetstats() are the sum
over all processes belonging to program id on this node, including those that have
already exited.
Setting id to -1 instructs the RMS kernel module to return values for the caller’s
program. Resource utilization statistics are available to the owner of the program and to
any process with administrator privileges.
