I'd hardly call OpenMP lightweight. I agree that as a meta-notation for directing the compiler how to insert appropriate code to force multithreading of certain classes of code, using OpenMP generally beats manual coding of the threads. But OpenMP is very Fortran oriented even though it can be useful for C, and indeed C++ as well. However, given things like Threading Building Blocks (TBB) and the functional programming inspired techniques used by Chapel, OpenMP increasingly looks like a "hack" rather than a solution. Using parallel versions of for, map, filter, reduce in the language is probably a better way forward. Having a D binding to OpenCL (and OpenGL, MPI, etc.) is probably going to be a good thing. -- Russel. ============================================================================= Dr Russel Winder t: +44 20 7585 2200 voip: sip:russel.win...@ekiga.net 41 Buckmaster Road m: +44 7770 465 077 xmpp: rus...@russel.org.uk London SW11 1EN, UK w: www.russel.org.uk skype: russel_winder
