Subject: Re: [OMPI users] running an open mpi application on hadoop ??

Those are quite different questions. MPI on Hadoop (if you mean using MPI from within a Hadoop application) isn't really possible at the moment, but will be soon.

MPI in a cloud environment is certainly doable - some of the folks on this list have reported using it with success on Amazon, for example. There are a few things you need to do to work thru the security firewalls, but it works okay once you do - not the best performance, but still workable.

Some of the references on this subject in our user mailing list are a bit old, but still might be useful:
