I would suggest the first place you check is some data structures that expand as the number of MPI processes increases. — Huiwei On Apr 20, 2014, at 10:08 AM, Hans-Joachim Werner <[email protected]> wrote:
Thanks. Yes, most likely it runs out of some system resources. It happens independently of the other memory the job needs. We use Global Arrays with MPI, and the problem happens in ga_put (one-sided write to a global array). We can also run it with pure MPI, and the same problem occurs (it’s not SHMMAX). The application is the Molpro quantum chemistry program.

It’s possible your system is running out of memory or other system resources that cause the MPI job to abort.

This is not an MPICH problem. It means that your application is asking MPICH to kill it using “MPI_Abort”.

On my system large jobs die with messages like this:
Last System Error Message from Task 3:: Inappropriate ioctl for device application called MPI_Abort(comm=0x84000004, 11) - process 3
Does anybody know how this can be avoided? Maybe a stack overflow?
