Re: Interested about number crunching in Ada

the issue of Ada compilers i.r.o. performance for numerics (it exists: at 
least, there is a performant one, HP Ada). Now, there are two missing aspects:

- even if you intend to use Ada for number crunching, you don't need to 
translate all the large building blocks that are presently in Fortran: Ada 
provides the Import and Convention pragmata. If you look at GNAT's sources 
behind the new Ada.Numerics.Generic_Real_Arrays, you will see that it cleverly 
uses the famous and broadly-tested and possibly non-GNU-compiled BLAS and 
LAPACK libraries.

- for small and/or less tested pieces of code, it is relatively easy to 
translate them with the f2a tool and the amount of bugs that pop during the 
Ada-ptation is not boring at all!

Maybe a kind of Sourceforge repository for Ada numerical code would be a good 
idea - any volunteer ? At least, there would be several contributors...
