Hi guys,

I got this error after submitting my job:

LAMMPS (1 Jun 2012)
Reading data file …

mpiexec_raw: Warning: task 0 died with signal 11 (Segmentation fault).
mpiexec_raw: Warning: tasks 1-35 died with signal 15 (Terminated).

Any idea what the cause is?

Daniel

Thanks Guys,

I have to use an older version of lammps since we are using a custom pair_airebo.cpp

In the error related to my lammps build?

It may be even related to your custom pair_airebo.

Try building your lammps executable for debugging and then backtrace an error in gdb to find where the problem occurs. Start with one MPI thread.

Oleg.
