This helps debugging the parallel performance of Haskell programs, making easier to check that work is well balanced across the available processors and spot performance issues relating to garbage collection or poor load balancing.
Using Threadscope ----------------- In order for threadscope to be useful, you have to compile your Haskell program to use the threaded run-time and also to create runtime profile logs, e.g. $ ghc -threaded -eventlog --make Foo.hs -o foo Once the program is built, execute it using the multithreaded run-time, specifying the number of cores to use in the usual manner, but also requesting the crea more»
