threadscope

a graphical thread profiler for Haskell programs

Variants:
Threadscope is a graphical thread profiler for Haskell programs. It parses and displays the content of .eventlog files emitted by the GHC 6.12.1 and later runtimes, showing a timeline of spark creation, spark-to-thread promotions and garbage collections.

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
