As I have said before, I don't think that it is a feasible objective, as there are several fundamentally different models involved, but I do agree that studying the issue is a good idea. Can anyone Email me a link to the CPLEX referred to here, as a simple search gets a lot of false positives? In particular, I believe that WG5 should at least keep in touch with initiatives on SIMD and tasking models (message-passing is already covered). Fortran is ahead of the pack on the former, and it would be a good idea to maintain that position! And at least some simple forms of the latter would be easy - which is not to say that they should be standardised. Regards, Nick Maclaren.
