import Picosat
import Control.Applicative
main :: IO ()
main = do
dimacsList1 <- (read <$> getLine) :: IO [[Integer]]
dimacsList2 <- (read <$> getLine) :: IO [[Integer]]
res1 <- solve dimacsList1
res2 <- solve dimacsList2
putStrLn $ (show res1) ++ " " ++ (show res2)
Question: How can I change the above example to run the two sat calls in parallel, i.e., using concurrency? I am interested in performance, if there are different options.
(Just to check: As I understand it, the ST monad is orthogonal and cannot be used in conjunction with parallelization/concurrency. The ST monad confused me a bit in the beginning, is is one of the reasons I ask the question.)
The easiest approach is to use the async library. Something like this, maybe.
[res1, res2] <- mapConcurrently solve [dimacsList1, dimacsList2]
