Whatever you do, you should seriously contemplate basing your work on
the NEC4 engine, rather than the older NEC 2 engine. Sure, you'll
have to pay for it, but it's structured better for what you want to
do, and more accurate to boot.


I was recently told that the non-commercial NEC-4 license doesn't include
source code. I haven't confirmed this, but it's something you should
investigate before purchasing an NEC-4 license if you intend to modify the
source code.


You'll also, of course, need a Fortran compiler capable of compiling a
multi-threaded application.

I have a non-commercial license, and it came with NEC 4.1 FORTRAN
source code.

I'll jump in here without knowing much about the program, but in
general having the Fortran source code doesn't do much to solve your
problem. The function calls to the run-time system is where the
problems will occur. Unless there are versions that support multi-
processors, you are still screwed.
