Subject: Re: [OMPI users] Using PMI as RTE component
From: Ralph Castain (rhc_at_[hidden])

I wouldn't trust that PMI component in the RTE framework - it was only created as a test example for that framework. It is routinely broken and not maintained, and can only be used if forced.

Is this on the trunk? Or are you using the 1.8 series? If the latter, that component shouldn't even be there.
