in a quick glance it looks like it just does a 'fork()'

glad to hear you say that as that is what i thought too.  -Ogv is not enough
on the the link though, as -nc is needed.  (not intuitively obvious)

ex:
via makefiles.....

fortran -c node.f
fortran -Ogv -o n node.o /usr/local/intel/bsimlib.a
-wants to run on the complex

fortran -c node.f
fortran -Ogv -nc -o node node.o /usr/local/intel/bsimlib.a
-makes it run on individual ce's, which is what i wanted.
