Hello,
I am interested in implementing some multi-threaded algorithms in Haskell.
I have run into some documentation dead-ends. The documentation in GHC.Conc is what I get when I search for "ghc pseq" on google, but it doesn't document pseq and some other functions:
pseq par forkOnIO childHandler ensureIOManagerIsRunning
In particular, I wonder: How is pseq different from seq?
See the current library docs: http://www.haskell.org/ghc/dist/current/docs/libraries/base/Control-Parallel... This is what will appear in GHC 6.8, except that Control.Parallel has now moved into the parallel package (and the online docs don't seem to reflect this, which is strange - Ian, any ideas?). In GHC 6.6.x you need to get pseq from GHC.Conc. We noticed this mistake only after the 6.6 release.
Also, the following functions in Control.Parallel.Strategies are not documented, at least in Haddock:
That module has better documentation now, follow the link above. Cheers, Simon
