On one of the system, the MPI coming with the system was not built with gfortran but g77. On the other system, I am using the Intel MPI library, so I am not sure I can use gfortran in place of ifort.
It could be due to a problem with MPICH1, but the Intel MPI library is MPICH2, and the problem persists.
Memory shouldn't be a problem, as this DFT job actually use very little memory.

My solution was to use gfortran which is a part of gcc. Note that I am using the most recent version 4.6. I also had run into memory problems using MPICH1. Simply using MPICH2 fixed those problems.
Let me know if this helps.
Also, be sure to run the script that automatically sets your memory to the correct value. I'll bet your system has more than 400MB per core. |
