Thank you.
My OS (Kubuntu 14.04).
ulimit is already set to unlimited.
When I generate exception (abort() function or divide by zero) I always get a core file,
but when MPICH fails (for example with MPI_Abort) no core file created.
May be I need to change any other settings?


Regards,
Anatoly.

The core file is created by the OS, not MPICH. What’s the output of ‘ulimit -c’ on your machine? Could you set ‘ulimit -c unlimited’ and try again?
