Chapter 9, Parallel and Concurrent Design, introduces advance topics in Haskell such as forking IO actions, mapping over lists in parallel, and benchmarking performance.
This is the accompanying source code for Haskell Data Analysis Cookbook. Refer to the book for step-by-step explanations.

Install the Haskell Platform.
$ sudo apt-get install haskell-platform
Alternatively, install GHC 7.6 (or above) and Cabal.
$ sudo apt-get install ghc cabal-install
A Makefile
is provided in each recipe. Compile the corresponding executable by running make
.
$ make
Run the resulting code. For example,
$ ./Code01
To clean up the directory:
$ make clean
