HaBench

Haskell Benchmark Suite

Recent discussions have illustrated the need for an up-to-date Haskell benchmark suite. The goal would be to package a number of representative benchmarks, written in Haskell, which users can run on their machine. Gathering (and publishing) performance numbers for these benchmarks on a number of different machines will hopefully help in guiding future development of both Haskell compilers and programs.

Naming

 * HaBench (intented to be the Haskell Benchmark Suite)
 * nofib/nofib 2.0 (follow-up of well-known nofib)

Ideas

• start from the (out-of-date?) nofib benchmark suite (GHC-only, includes ghcisms, but very usefull programs (gzip in pure Haskell, a whole strictness analysis pass of a compiler, quantum mechanics simulator and other _real_ stuff (JohnMeacam)) (website)
• include Computer Language Shootout submissions (website)
• YHC regressions suite (URL)
• microbenchmarks for comparison with C (for example bytecopying) (dons)
• both a Haskell98 and Haskell'-only (sub)suite (JohnMeacam)
• multiple Haskell compilers (GHC, JHC, ...)
• maintain benchmark according to Hackage (Hackage list)
• Rename this project as nofib, otherwise it is like that people will have to run both this and nofib, because people will ask for the nofib results as well (ndm)
• Libraries and tools in Haskell

Notes

Random notes are below.

• (JohnMeacham) Insert non-formatted text here pretty much every compiler has a mode similar to 'ghc --make', so just let the user specify an arbitrary command line for the compiler to use, like 'jhc -v -flint $< -o $@' or 'ghc --make $< -o $@'
