Ralph, > Are you getting those messages from ompi_info? Or from an MPI app >(and if so, what are you doing to get them)?
They're coming out of a user's application. Reason I just wanted to check about what the errors are saying is that things are still in tesing mode wrt the IB kit though, as I say, I thought I had poked two variables into the node-local MPI environment, so was surprised to see the second of those numbers. Am getting the user to run the code with those variables set explictly, which might answer the supposition I have. Kevin -- Kevin M.
