Execute the same function multiple times in parallel in Clojure?

Question

I have a function that I'd like to run multiple times, generating a list of the results:

(take 10 (repeatedly #(myfunc)))

I realized I could run them in parallel with pmap:

(pmap (fn [_] (myfunc)) (range 10))

But it is a bit untidy. Is there a standard function that lets me do this Something like:

(prun 10 #(myfunc))

?

Answer 1

You may also be interested in The Claypoole library for managing threadpools and parallel processing. Look at their version of pmap and pfor.

Answer 2

I don't think there's an existing function, but using pcalls rather than pmap seems a little closer to what you want:

(defn prun [n f]
  (apply pcalls (repeat n f)))

You don't need to wrap myfunc with #() in the call torepeatedly, btw, nor calling prun as defined above:

(prun 10 myfunc)

You may find pvalues useful as well.
