I've just released ThreadScope version 0.1 on Hackage. Threadscope is a graphical utility for viewing profiling information about Haskell threads. It was written jointly with Simon Marlow and Donnie Jones. It uses Gtk2HS so it works under Windows and the L-word operating system although there seem to be problems making it work with OS-X (due to Gtk2Hs issues I think). $ cabal install threadscope You may need to do cabal update to update your packages list. On Windows operating systems you may need to issue the command from a shell that is running with administrative privileges. Resources: * Web page: http://research.microsoft.com/threadscope * Parallel Performance Tuning for Haskellhttp://research.microsoft.com/apps/pubs/default.aspx?id=80976 (paper at Haskell Symposium 2009) Please let me know if you have any problems. Also, please do let us know about your experience with ThreadScope and in particular about accounts of how you used ThreadScope to shed light on parallel performance bugs. If I get enough feedback I may collate the responses into an experience report or paper for ICFP or the Haskell Symposium. Thank you kindly. Enjoy!
