Mike and Ralph, i could not find a simple workaround.
for the time being, i commited r31926 and invite those who face a similar issue to use the following workaround : export OMPI_MCA_rtc_freq_priority=0 /* or mpirun --mca rtc_freq_priority 0 ... */ Cheers, Gilles On Mon, Jun 2, 2014 at 3:45 PM, Gilles Gouaillardet < gilles.gouaillar...@gmail.com> wrote: > 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. >
