[mpich-discuss] A problem in running mpi code on ubuntu 13.10

[Kenneth Raffenetti]

This problem usually comes from having a mix of openmpi and mpich both 
installed on the same machine. Is that the case? You can search for 
openmpi by running something like this from the command line:

   dpkg -l | grep openmpi
