Hi,
I'm having a bit of a problem with wrapping mpirun in a script. The
script needs to run an MPI job in the background and tail -f the output.
Pressing Ctrl+C should stop tail -f, and the MPI job should continue.
However mpirun seems to detect the SIGINT that was meant for tail, and
kills t
just worsen the values.
Anyway, why does mpirun bypass the traps I try to set and how do I stop it
doing so?
Thanks,
Pablo

tail -f out
also has the same effect. How is mpirun overriding the trap in the *parent*
subshell so that it ends up getting the SIGINT that was supposedly blocked at
that level? Am I missing something trivial? How can I avoid this?

I simply want a script that runs the equivalent of:
mpirun command>& out&
tail -f out
such that hitting Ctrl+C stops tail but leaves mpirun

ou can't kill mpirun when something goes wrong
