bmp2xpm is an embarrassingly simple image processing program which converts BMP (v3) files to XPM (v3) files. I'm writing this to get a better idea of parallel programming in Haskell.
To build and run this program, do this:
cabal build
cabal exec bmp2xpm input.bmp output.xpm
Use a sandbox if you need to.
For a profiling build, do this:
ghc -O2 -rtsopts -threaded -prof -auto-all Main.hs -o Main.exe
We will need profiling libraries. We might also need ghc-prof.
To review eventlog under ThreadScope, compile the program like below, run the program, and then open the resulting Main.exe.eventlog file in ThreadScope:
ghc -O2 -rtsopts -threaded -eventlog Main.hs -o Main.exe
Note that -eventlog and -prof are mutually incompatible.
