I'm very sorry. My mistake. foldP works as expected as shown by the code below:

{-# LANGUAGE PArr, ParallelListComp #-} {-# OPTIONS -fdph-seq #-}

module Test where

import GHC.PArr

boolArr = [: False, False, False :]

isTrue :: Bool isTrue = foldP (||) False [: x | x <- boolArr :]

Here the result of "isTrue" is False, as expected. So, seems that the only problem is about "elemP"

Sorry again.

Luca.

Ok, Thanks. This works fine. I found out that also mapP and sumP are working as expected, but elemP and foldP do not behave correctly.

Have you a short example of foldP behaving wrongly? The dph people will have it easier to find the bug if they have one.

Cheers, Daniel
