Kill all mpd.py processes.

Then run

mpdboot -n 1

and afterwards

mpiexec -l -np 4 /home/Berti/Desktop/pypcsim-0.5.0/_build/bin/pcsim_test


You can also try the following:
Kill all mpd.py processes and run

mpdboot -n 1
mpdtrace -l

or run mpdboot -n 1 twice

to see what happens.

When an active client process tries to connect with a client socket to 
the mpd server, it fails.
This will confirm that the problem is with mpich2.
