I noticed that hackbench returns a random status in $? ... it's because
there's a couple of lines missing from the original.
In ./testcases/kernel/sched/cfs-scheduler/hackbench.c, the last lines
are:
/* Reap them all */
for (i = 0; i < total_children; i++)
reap_worker(pth_tab[i]);
gettimeofday(&stop, NULL);
/* Print time... */
timersub(&stop, &start, &diff);
}
The original (from
http://people.redhat.com/mingo/cfs-scheduler/tools/hackbench.c) has this:
/* Reap them all */
for (i = 0; i < total_children; i++)
reap_worker(pth_tab[i]);
gettimeofday(&stop, NULL);
/* Print time... */
timersub(&stop, &start, &diff);
printf("Time: %lu.%03lu\n", diff.tv_sec, diff.tv_usec/1000);
exit(0);
}
