Try running 'sudo update-alternatives --set mpi<br>
/usr/include/mpich2'. This tells the Ubuntu alternatives system to<br>
use mpich2 by default.<br>

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

In the program you cited you don't output the<br>
size. Can you<br>
output<br>
the size in addition?<br>
