Following recent discussion about a cross-implementation performance benchmark suite, based on nofib, I've gone and combined nofib with the great language shootout programs, and rewritten the build system to support cross implementation measurements. The result is: nobench http://www.cse.unsw.edu.au/~dons/nobench.html The benchmark suite runs regularly, and currently reports the speed of each program in the suite, running under each system. The results are quite interesting. The most recent run is available: http://www.cse.unsw.edu.au/~dons/nobench/bench.results http://www.cse.unsw.edu.au/~dons/nobench/bench.log The programs are a mixture of traditional nofib style Haskell, with more performance-tuned code from the shootout. More tweaking is required to help better support nhc and yhc (and jhc, and ...). The entire benchmark set and framework is available via darcs: darcs get http://www.cse.unsw.edu.au/~dons/code/nobench Currently todo are porting the rest of nofib, pretty graphs of the results (and html), and memory use measurements. Patches welcome! Cheers, Don
