Hello, Following up and the threads on haskell and haskell-cafe, I'd like to gather ideas, comments and suggestions for a standarized Haskell Benchmark Suite. The idea is to gather a bunch of programs written in Haskell, and which are representative for the Haskell community (i.e. apps, libraries, ...). Following the example of SPEC (besides the fact that the SPEC benchmarks aren't available for free), we would like to build a database containing performance measurements for the various benchmarks in the suite. Users should be able to submit their results. This will hopefully stimulate people to take performance into account when writing a Haskell program/library, and will also serve as a valuable tool for further optimizing both applications written in Haskell and the various Haskell compilers out there (GHC, jhc, nhc, ...). This thread is meant to gather peoples thought on this subject. Which programs should we consider for the first version of the Haskell benchmark suite? How should we standarize them, and make them produce reliable performance measurement? Should we only use hardware performance counters, or also do more thorough analysis such as data locality studies, ... Are there any papers available on this subject (I know about the paper which is being written as we speak ICFP, which uses PAPI as a tool). I have created a HaskellWiki page (http://www.haskell.org/haskellwiki/ HaBench) in order to centralize ideas and suggestions. Feel free to add anything, and if you're willing to contribute to this project (in any way), add your name to the wiki for future reference. greetings, Kenneth (a.k.a. boegel) -- Statistics are like a bikini.
