I have set up an interface between IDL and PVM (the Parallel Virtual
Machine). You can see a blurb about it at

I have used it for some massive runs that would have been impossible without
the parallel processing. The way I have the code set up you can either run
an IDL save file as a "slave" program or a C or Fortran program  as a slave.
If you stay completely with IDL it is even a little easier than regular PVM
as IDL always knows the data type and size so you don't have to explicitly
state these like you would in a regular C (or Fortra) PVM program.

If you are interested in learning more send me an email.
