[Haskell-cafe] Control.Parallel seemingly randomly behaviour

[Johannes Waldmann]

Hi Juan, I am interested in this because I use
Control.Parallel in teaching currently. But -

* what is your actual Main program / main function
  (it was not included in your message?)
* what is your actual cabal / stack config file?
* on what machine (OS, CPU) are you running this (it seems pretty slow)?
* have you looked at eventlogs with threadscope?

- J.
