I tried to implement the -notify + trap USR2 solution, but could not get it to work. I can trap the USR2 signal in the qmaster PE script, but as soon as it is sent, the slave tasks get killed, leaving my application no time to cleanly shut them down. The qmaster log displays:
*tightly integrated parallel task 61969.1 task 1.computeXX failed - killing job* The queue is configured with "notify 00:00:60", so that should leave at least one minute. I also tried to trap USR2 in the PE script and not forward it all to child processes, but slave tasks still get killed. Is there something else specific to do to avoid this? 2012/9/19 Julien Nicoulaud <[email protected]> > Yes, that's what I meant.
