We've discussed several times how Java isn't really well suited to
scientific computing for various reasons. I was wondering if there is a
write once run anywhere language that is suited to scientific computing.

Before you give up on Java, try out Jet, and see how well it compiles
your number crunching code. http://mindprod.com/jgloss/jet.html


Another approach is to use Java for your UI, then have it use JNI to
call your number cruncher written in whatever you find is best for the
various platforms you need ot support, and simply recompile it for
each platform. Without UI it should need precious little tweaking, or
only mechanical tweaking.

Sometimes all you need it a very few lines of assembler for the
innermost loop. You can warp your algorithm around some special
property of the CPU, e.g. the vector processing.
