man getrusage.

Pay special attention to the RUSAGE_SELF or RUSAGE_CHILDREN
flag, but I think current linux kernel does not perform a correct account
for threads rusage in the parent. Probably you will have to account each
thread, return info to the parent and sum or average (sum cpu times,
average elapsed times...)
