Subject: Re: [OMPI users] Java MPI Bindings in 1.6.x

FWIW: Greenplum is about to release exactly that solution based on OMPI, though it will require the OMPI trunk. Not back portable to v1.6 I'm afraid, but allows you to run Hadoop on any cluster as opposed to requiring dedicated hardware.

I can get an early-adopter release for you, if it helps.
