What is the simplest way to translate a non-monadic line of Haskell code, such as:
res = map foo xs `using` parList rseq
For use in the IO monad?
This doesn’t work:
res <- mapM fooM xs `using` parTraversable rseq
The docs for Control.Parallel.Strategies say "The parallel tasks evaluated by a Strategy may have no side effects. For non-deterministic parallel programming, see Control.Concurrent."[1]. So I guess you should look into Control.Concurrent[2].
