The DaCapo Benchmark Suite

Last updated 2018-04-06

This benchmark suite is intend as a tool for the research community. It consists of a set of open source, real world applications with non-trivial memory loads.

Guidelines for use

When quoting results in publications, the authors of this suite strongly request that:

  • The exact version of the suite be given (number & name)

  • The suite be cited in accordance with the usual standards of acknowledging credit in academic research.

  • Please cite the 2006 OOPSLA paper

  • All command line options used be reported. For example, if you explicitly override the number of threads or set the number of iterations, you must report this when you publish results.

For more information see the DaCapo Benchmark web page.

Building

The easiest way to obtain the benchmark suite is to download the pre-built jar file from the DaCapo Benchmark web site above.

If, however, you want to build from source read on...

The suite is built using ant 1.10. You will need the following tools:

  • ant 1.10 You need to install this yourself if you don't already have it.

  • javacc Included in our tools directory.

  • maven Included in our tools directory.

  • cvs

  • svn

  • hg

NOTE

1.JDK 8 is needed to build the whole suite. 2.Building DayTrader and PMD using JDK 8 also requires JDK 7 to be installed, and jdk7home properly set. (see 2 below)

IMPORTANT: before trying to build the suite:

  1. Set your JAVA_HOME environment variable appropriately (it must be set and be consistent with the VM that will be used to build the suite).

  2. Copy default.properties to local.properties and edit it for your environment.

  • Specifically, you must set jdk7home to point to a Java 7 installation.

For more information, run ant -p in the benchmarks directory.

Customization

It is possible to use callbacks to run code before a benchmark starts, when it stops, and when the run has completed. To do so, extend the class Callback (see the file harness/src/MyCallback.java for an example).

To run a benchmark with your callback, run:

java -jar dacapo.jar -c <callback> <benchmark>

Source Code Structure

harness (The benchmark harness)

This directory includes all of the source code for the DaCapo harness, which is used to invoke the benchmarks, validate output, etc.

bms (The benchmarks)

  • bms/<bm>/src Source written by the DaCapo group to drive the benchmark <bm>
  • bms/<bm>/downloads MD5 sums for each of the requisite downloads. These are used to cache the downloads (avoiding re-downloading on each build)
  • bms/<bm>/data Directory containing any data used to drive the benchmark
  • bms/<bm>/<bm>.cnf Configuration file for <bm>
  • bms/<bm>/<bm>.patch Patches against the orginal sources (if any)
  • bms/<bm>/build.xml Local build file for
  • bms/<bm>/build Directory where building occurs. This is only created at build time.
  • bms/<bm>/dist Directory where the result of the build goes. This is only created at build time.

libs (Common code used by one or more benchmarks.)

Each of these directories more or less mirror the bm directories.
