This is the sample code to accompany the book Parallel and Concurrent Programming in Haskell (Simon Marlow, O'Reilly 2013).

To build the code on your system, you need either:

Building with Stack

stack build

will build all the executables and install them in a platform-specific subdirectory under .stack-work/install.

Building with Cabal new-build

cabal new-build

cabal sandbox init
cabal install --only-dependencies
cabal configure
cabal build
