ghc-parmake: A parallel wrapper for 'ghc --make'.

[ bsd3, development, library, program ] [ Propose Tags ]

ghc-parmake is a parallel wrapper for 'ghc --make' intended to work as its drop-in replacement. It can build your Haskell program in parallel using multiple cores. ghc-parmake works by extracting a module dependency graph with 'ghc -M' and then running multiple 'ghc -c' processes in parallel. To set the number of concurrent jobs, use the -j option.

ghc-parmake

ghc-parmake is a parallel wrapper for ghc --make intended to work as its drop-in replacement. It can build your Haskell program in parallel using multiple cores and will be integrated with cabal build eventually (though I also plan to support the standalone version).

To use it with cabal, try cabal build --with-ghc=ghc-parmake --ghc-options="-j N".

ghc-parmake works by first extracting a module dependency graph with ghc -M and then running multiple ghc -c processes in parallel. Currently, it can build itself and some small test programs (see the tests directory).

To set the number of concurrent jobs, use the -j option.

Usage

ghc-parmake OPTS FILES

-j N             - Run N jobs in parallel.
--ghc-path=PATH  - Set the path to the ghc executable.

-vv[N]           - Set verbosity to N (only for ghc-parmake).
                   N is 0-3, default 1.
-v[N]            - Set verbosity to N (both for GHC and ghc-parmake itself).
--help           - Print usage information.
-V               - Print version information.

Other options are passed to GHC unmodified.

Known limitations

Build fails when -odir != -hidir.
Tested only on Linux.
