Re: [ESPResSo] eps mpi run problem

[Axel Arnold]

Please provide the full error message, so far it only says that somewhere while 
executing Espresso, a segfault appeared.

A seg fault can have many different reasons, either a bug, or a problem with 
the MPI library or similar. One common problem is that you are not letting your 
system relax slow enough, and it explodes. In rare cases, you will then get a 
segfault instead of an error.
