Any thoughts would be welcome.
As a major convenience over starting separate threads by hand I would use "future". For each invocation future will run a given function on a different thread. You can then either dereference each future which will block until the function completes or ask if a future has completed with "future-done?". (You can also see futures used in the source of the pmap core function). See Sean Devlin's very helpful introduction to futures at: http://vimeo.com/8320428 It is not clear to me from your description if the agent is just aggregating data from the separate threads or is actually required for the threads to coordinate as they run, in the latter case you are in deeper water than I have swum in so far. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
