Hello Doug,

I guess your friend is aware of this:

http://www.hpjava.org/

(a Java wrapper to interface with a native MPI package).
What speaks against this?

>   2. java runs 3-4 times slower than C, C++, Fortran, and machine time
>   is expensive, and finally

There have already been many studies (also published on this
list ;-) that this is a prejudice. Java apps can be made to
run just as fast as C/C++ - if you take care programming.
(I _don't_ want to start a language war!)

Best Regards,
Günther
