Since this is old Fortran, I suspect that the given simulation can
only use one core. It also may be limited in the memory it can use or
does use. Having a good optimizing compiler would help and one may or
may not be available for the box used. There may be code which was
optimal for the environment in existence when written but
counter-productive in the current environment. I know that
optimization that I did for COBOL VS was in some ways
counter-productive in VS COBOL II 1.4 and later.

Would this be "OLD" FORTRAN because someone knows that FORTRAN is
an "old" language, or would this be "OLD" FORTRAN II?
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,
