[mpich-discuss] MPICH 3.1 fails doesn't create core file.

[Anatoly G]

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.
