threadscope: A graphical tool for profiling parallel Haskell programs.

This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.

[maintain] [Publish]

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.

ThreadScope

Hackage Hackage-Deps Build Status Build status

Using pre-built binaries

Currently pre-built binaries for the following platforms are provided:

GTK+2 needs to be installed for those binaries to work.

On Windows, the MSYS2 is the recommended way to install GTK+2. In MSYS2 MINGW64 shell:

pacman -S $MINGW_PACKAGE_PREFIX-gtk2

then you can run the threadscope binary from the shell.

Building from source

Use git clone or cabal unpack threadscope to get the source and move into the threadscope directory.

Linux

GTK+2 is required to be installed. On Ubuntu-like systems:

sudo apt install libgtk2.0-dev

Then you can build threadscope using cabal:

cabal v2-build   # to only build the project, or
cabal v2-install # to build and install the binary

Or using stack:

stack build   # to only build the project, or
stack install # to build and install the binary

OS X

GTK+ and GCC 9 are required:

brew install gtk+ gcc@9

Then you can build threadscope using cabal:

cabal --project-file=cabal.project.osx v2-build   # to only build the project, or
cabal --project-file=cabal.project.osx v2-install # to build and install the binary

Or using stack:

stack --stack-yaml=stack.osx.yaml build   # to only build the project, or
stack --stack-yaml=stack.osx.yaml install # to install the binary

Windows

Chocolatey can be used to install GHC and MSYS2 is the recommended way to install GTK+.

choco install ghc
refreshenv
set PATH=C:\\msys64\\mingw64\\bin;C:\\msys64\\usr\\bin;%PATH%
pacman -Sy mingw-w64-x86_64-gtk2

then you can build threadscope using cabal:

cabal v2-build

Or you can use stack instead.

CAVEAT: gtk2 needs to be installed twice: one for stack's MSYS2 environment and another for local MSYS2 environment.

In command prompt:

stack setup
stack exec -- pacman --needed -Sy bash pacman pacman-mirrors msys2-runtime msys2-runtime-devel
stack exec -- pacman -Syu
stack exec -- pacman -Syuu
stack exec -- pacman -S base-devel mingw-w64-x86_64-pkg-config mingw-w64-x86_64-toolchain mingw-w64-x86_64-gtk2
stack install

Then in MSYS2 MINGW64 shell:

pacman -S $MINGW_PACKAGE_PREFIX-gtk2
echo 'export PATH=$APPDATA/local/bin:$PATH' >> .profile
source .profile
threadscope

Building using stack is not tested in CI. If you find any issues with building with stack, please update the instructions and send a PR.
