I’ve lost track of the earlier parts of this thread, but has anyone suggested
logging into the nodes it’s running on, doing “gdb -p PID” for each of the mpi
processes, and doing “where” to see where it’s hanging?
I use this script (trace_all), which depends on a variable process that is a
grep regexp that matches the mpi executable:
echo "where" > /tmp/gf
pids=`ps aux | grep $process | grep -v grep | grep -v trace_all | awk '{print
\$2}'`
for pid in $pids; do
echo $pid
prog=`ps auxw | grep " $pid " | grep -v grep | awk '{print $11}'`
gdb -x /tmp/gf -batch $prog $pid
echo ""
done
