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. On Sun, Oct 12, 2014 at 4:47 PM, Lu, Huiwei <[email protected]> wrote:

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?

Dear MPICH. I'm using MPICH3.1 After application run of 4-5 hours Master process fails, but it doesn't creates a core file. When I used MPI_Abort (in the past) it not creates core file too. Can I make MPICH create core in any fail (of course if it's MPI fail).

Regards, Anatoly.
