More precisely, no proposals since you have joined the discussion. There have been proposals in the past that would create a "real" Fortran interface for MPI that was completely different from the C interface. It would use assumed-shape dummies. (Solves the copy-in/copy-out problem.) With the associated descriptors, a large number of the arguments to MPI routines could be dropped. (Improves on the difficulty of use problem and reduces coding mistakes.)

OK. Yes, that's very different. But it's completely orthogonal to the non-blocking/ASYNCHRONOUS issue. Regards, Nick Maclaren, University of Cambridge Computing Service, New Museums Site, Pembroke Street, Cambridge CB2 3QH, England. Email: [email protected] Tel.: +44 1223 334761 Fax: +44 1223 334679
