Do I detect shades of Automatic Binary Optimizer for FORTRAN? Would developing that app be worth $50K? Maybe a new project for Connor...

I'm thinking, to even get this to work on the "massively parallel" system it is running on, that one is having to use the compiler for that O/S. If that is the case, and they can get their version of FORTRAN 77 (?) to process the source, then this code is probably already doing multi-tasking for as much as the compiler can determine can be done. Now, if one knows the system, and one knows the various implementer extensions, one probably could make this run faster. This has one wondering if this code was originally running on an OLD Cray or something similar. But then again we all know that "OLD" COBOL 6 is running a lot of "OLD" COBOL source to make lots of money out of obsolete programs that process obsolete transactions on "OLD" obsolete Mainframes to make a lot of obsolete Bit Coin... Wait! What? Yeah, Regards, Steve Thompson ps.
