Mike and Ralph, i got the very same error.
in orte/mca/rtc/freq/rtc_freq.c at line 187 fp = fopen(filename, "r"); and filename is "/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor" there is no error check, so if fp is NULL, orte_getline() will call fgets() that will crash. that can happen for example if the intel_pstate (or similar) kernel module is not loaded on a CentOS 6, or if the intel_pstate kernel module is not even present (depending on how the linux kernel was built) Cheers, Gilles On Mon, Jun 2, 2014 at 1:19 PM, Ralph Castain <r...@open-mpi.org> wrote: > It's merrily passing all my MTT tests, so it appears to be fine for me. > > It would help if you provided *some* information along with these reports > - like how was this configured, what environment are you running under, how > many nodes were you using, etc. Otherwise, it's a totally useless report. > > >
