Also, pmap maps one sequence item to one task, so it doesn't make sense to use it when the individual sequence items are tiny jobs. (Of course you could do your own mapping of chunks of vector elements to jobs.) However, your example below suggests this isn't the cause of the heap overflow. mfh --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Clojure" group.
