ikarus/benchmarks

This directory contains the Gambit benchmarks and benchmarking
infrastructure, written by Marc Feeley.  Will Clinger has hacked
it up to run benchmarks on the machines used by the Larceny
project, and has added several benchmarks beyond those
distributed with Gambit.  Abdulaziz Ghuloum converted them to
R6RS libraries and added an ikarus-specific bench.ss for running
the benchmarks under ikarus.

Files and directories:

  * bench.ss: a script for running a benchmark
  * rnrs-benchmarks.ss: a library specifing the number of
    iterations that every benchmark should be run and some
    procedures (like run-benchmark) that the various benchmarks
    use.
  * rnrs-benchmarks/*: the actual benchmark libraries.
  * rn100, bib, parsing-data.ss: used by some benchmarks.

To run a benchmark, type:

  $ ikarus --r6rs-script bench.ss <benchmark-name>

Example:

  $ ikarus --r6rs-script bench.ss nucleic
  running stats for compile-nucleic:
      7 collections
      262 ms elapsed cpu time, including 84 ms collecting
      262 ms elapsed real time, including 84 ms collecting
      30095456 bytes allocated
  running stats for nucleic:
      154 collections
      840 ms elapsed cpu time, including 77 ms collecting
      842 ms elapsed real time, including 78 ms collecting
      640581192 bytes allocated

The text that Ikarus's "time" macro and "time-it" procedure
output is modeled after Chez Scheme's in order to facilitate
interoperability with tools that parse benchmark data.
