Everything in your note sounded fine, and the code certainly sounds
like it should multi-process well.

The thing to do is to profile the code. e.g.
     f77 -pfa keep -WK,-O=4,-UR=4 -O2 test.f -o test   -p
                                                      ^^^
and then run it again.  This will produce "n" pc-sample files (one for the
master process, and one for each slave process).  Then by looking
at them with prof e.g.
     prof test mon.out12345
you should be able to see what's going on.
