Hi Ali

I'm unaware of any firm plans to port either Open MPI or the underlying OpenRTE run-time to VxWorks, though I have had some initial contact from others interested in possibly doing so with the latter (part of a virtual telescope control and data processing system). Being fairly familiar with VxWorks, I think the OpenRTE port should be relatively straightforward - in fact, I think there is a high probability that it will work "out-of-the-box". Ditto for the Open MPI layer.

The only real issue might be in the atomics section and a handful of other places that actually configure themselves based on the operating system they "detect" in the local environment. We recognize OS names like Linux - I'm not sure what would happen within VxWorks. We might have to add a few lines here and there to recognize VxWorks, even though that system is based on Unix (the name probably comes back as specific to vxworks, as I recall).

Anyway, I'd be happy to help answer questions if you want to give it a whirl, and can connect you with others as they try (though that's probably a little ways off).

Looking at the OpenMPI web site, I couldn't find any reference to support for VxWorks.
Here are my questions:

       -  Is there any plan for OpenMPI to run on VxWorks?
       -  Does anyone has ported/customized OpenMPI to work on VxWorks?
       -  What level of effort does it take to port OpenMPI to run on VxWorks.
