The hsbencher package

[Tags:bsd3, library, test]

Benchmark frameworks are usually very specific to the host language/environment. Hence they are usually about as reusable as compiler passes (that is, not).

Nevertheless, hsbencher is an attempt at a reusable benchmark framework. It knows fairly little about what the benchmarks do, and is mostly concerned with defining and iterating through configuration spaces (e.g. varying the number of threads), and managing the data that results.

Benchmark data is stored in simple text files, and optionally uploaded via pluggable backend packages such as hsbencher-fusion, which uploads to Google Fusion Tables.

hsbencher attempts to stradle the divide between language-specific and language-agnostic by having an extensible set of BuildMethods. As shipped, hsbencher knows a little about cabal, ghc, and less about Make, but it can be taught more.

The general philosophy is to have benchmarks follow a simple protocol, for example printing out a line SELFTIMED: 3.3 if they wish to report their own timing, in seconds. The focus is on benchmarks that run long enough to run in their own process. This is typical of parallelism benchmarks and different than the fine-grained benchmarks that are well supported by Criterion.

hsbencher is used by creating a script or executable that imports HSBencher and provides a list of benchmarks, each of which is decorated with its parameter space. Below is a minimal example that creates a two-configuration parameter space:

import HSBencher
main = defaultMainModifyConfig $ addBenchmarks
.      [ mkBenchmark "bench1/bench1.cabal" ["1000"] $
.        Or [ Set NoMeaning (RuntimeParam "+RTS -qa -RTS")
.            , Set NoMeaning (RuntimeEnv "HELLO" "yes") ] ]

The output would appear as in this gist:
