threadscope (hackage): ThreadScope is a graphical viewer for thread profile information generated by the Glasgow Haskell compiler (GHC).  The Threadscope program allows us to debug the parallel performance of Haskell programs. Using Threadscope we can check to see that work is well balanced across the available processors and spot performance issues relating to garbage collection or poor load balancing.
