ParallelFox works only on the local machine. There are a multitude of methods for passing requests to a server, but besides DCOM, I would also take a look at COM+. Craig Berntson wrote some articles on the subject.

>>I had a project like that many years ago -- when security wasn't what it is today. It involved processing ACH transfers, which could pile up if a server went down, or if the flow was more than the existing servers could handle. I got it working, but it was cumbersome, and so I re-designed it to a) have one server be a listener; b) if a machine observed there was no listener, it became the listener; c) the listener assigned tasks to all machines that had registered as servers; d) if a task was assigned to a worker machine but went over a time limit, the Listener re-assigned the task to an open Worker. Thus, machines could be taken offline or added as needed (we didn't go so far as to fire up machines).

>>The one thing I would do if designing it today, which was irrelevant back then, is use ParallelFox to utilize all the cores on a given machine. Each Worker would have an exe that ran multiple tasks in Parallel. The exe would, on completion of a task, mark it finished in the workflow table, and grab another to be run by the now empty process. PFox is ridiculously easy to use, fwiw. Great job by Joel.
