Gentlemen, please note that the subject of this thread is: Ada on the super.
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" ;-)
