Hi,
at the lab we just purchased a clustervision computer (8 nodes of 8
CPUs each) ... 

1/ I tried ipython on a single node.
ipcluster -n 8
then 
ipython 
--> success

2/ with the admin. we would like to use the mpirun syntax as suggested
in the doc. we succesfully installed
- foolscap
- pyopenssl
- twisted 
- pexpect
- zope.interface

for mpi4py we just use the module provided by clustervision 
openmpi/gcc/64/1.2.2

and then a :
for mpi4py
$python setup.py install

for ipython
$python setup.py install

followed by
mpirun -n 4 ipengine --mpi=mpi4py
