I'm still a big fan of IDL, Rick, but $3000 for an educational license for
FastDL for an 8 CPU cluster + $450/yr maintenance is not small change. I'll
follow your suggestion and find out about a trial FastDL license. I don't
have any experience in parallel processing programming, and I have no doubt
that the devil is in the details in how much of an improvement one can
really get. What's unclear to me at this point is how much harder it would
be for me to develop my own communication links between separate IDL
processes on different CPUS than to rewrite the code using FastDL to do more
or less the same thing. Here is where having some substantial examples coded
in different ways would really help. For example, if I have 100 images to
process using identical code, it would not be that hard to start 8 IDL
processes on different CPUS and have each one grab the next available image.
I'm not sure how much more than this TaskDL does for this kind of operation.
Of course, doing parallel processing a finer level of things (miIDL) is a
different story, and here I know that I have a lot to learn.
