[mpich-discuss] ctrl-c while running mpiexec -gdb

[Darius Buntinas]

When you hit ^C from mpiexec (with or without -gdb), mpiexec will kill 
all processes and exit.  To send a SIGINT to the processes themselves, 
you would need to use mpdsigjob.  First find the jobid using 
mpdlistjobs, then send the SIGINT to the job:

   mpdsigjob SIGINT -j jobid

Give this a try.

-d
