Yes. Jeff has an account on my machine, so that he can look at
the problem as well. He can even use our system with little and
big endian machines, if he has time and if he wants that Open
MPI can use a real heterogeneous environment with different
architectures and not only different operating systems (LAM-MPI
can use all of our machines in a single job).
