AFAIK, there are no ports of gcc (and hence, GNAT) to Cray PVP, NEC SX, Fujitsu VPP and other "super" gear. A port to Cray PVP machines would be "interesting", as the current gcc backend doesn't even support the notion of an architecture not having byte addressability. Furthermore, gcc doesn't support the OpenMP (http://www.openmp.org) parallellisation directives, and neither has automatic parallellisation. Of course, it can be used with MPI (or PVM), but that requires "some more handy work" ;-) -- Toon Moene (mailto:toon@moene.indiv.nluug.nl) Saturnushof 14, 3738 XG Maartensdijk, The Netherlands Phone: +31 346 214290; Fax: +31 346 214286 g77 Support: mailto:fortran@gnu.org; NWP: http://www.knmi.nl/hirlam
