Did you look at pmap? You might be able to use something like (pmap (fn [_] (sample-for-pi count)) (range count)), and then use that in your guess-from-samples reduce. I'm thinking this might be better because it would handle more of the work: scaling to the number of CPUs, launching the agents, waiting for the results. I'm not sure it's a perfect fit -- perhaps pmap adds unneeded overhead. BTW, using "count" as a local name can cause surprises later when someone tries to use the clojure/count function. --Chouser --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
