Comment:

 Sorry for the delay.

 Numpy scipy, mpi4py, suitesparse, and openblas are all the latest
 versions.

 There is no traceback.  Here is my test.py:


 {{{
 from mpi4py import MPI
 from numpy import *
 }}}

 And as soon as I do:

 mpiexec -n 4 python test.py

 I get:


 {{{
 =====================================================================================
 =   BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
 =   EXIT CODE: 11
 =   CLEANING UP REMAINING PROCESSES
 =   YOU CAN IGNORE THE BELOW CLEANUP MESSAGES
 =====================================================================================
 APPLICATION TERMINATED WITH THE EXIT STRING: Segmentation fault (signal
 11)

 }}}

 However, when I do just python test.py everything is fine.

 I am very confused as this works perfectly on another account on the same
 machine that I compiled.
