To through in my $0.02, I would see a benefit in adding the component to the trunk. As I mentioned in the last teleconf, we are currently working on adding support for the HPX runtime environment to Open MPI, and for various reasons (that I can explain if somebody is interested), we think at the moment that using the RTE abstraction layer could be easier for achieving what we want to do. That is not at all a judgment on ORTE, but a combination of what HPX offers and what we want to achieve within that project.
I do not foresee at this point that our component would be production quality or part of an upcoming OMPI release, having however another component in the rte framework could be useful from our point of view. (And yes, the person that asked the pmi/rte question on the mailing list was my student who tried to make the pmi component work, and was confused about the fact that other emails said that the pmi stuff is working, while he couldn't even get it to compile :) Edgar On 5/27/2014 12:23 PM, Ralph Castain wrote: > I have mixed thoughts on this request.
