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.
When quoting results in publications, the authors of this suite strongly request that:
-
The exact version of the suite be given (number & name, eg 'dacapo-23.11-chopin')
-
The suite be cited in accordance with the usual standards of acknowledging credit in academic research.
-
Please cite the 2006 OOPSLA paper or a more recent paper by the DaCapo authors providing an up-to-date description of the suite if and when such a paper becomes available.
-
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. Likewise you should report exactly which JVM version you use, and all commandline options provided to the JVM.
For more information see the DaCapo Benchmark web page.
The easiest way to obtain the benchmark suite is to download the pre-built suite file from the DaCapo Benchmark web site above.
If, however, you want to build from source read on...
ant -p [prints out description, including configuration and environment variable settings]
ant [builds all benchmarks, creates a zip file]
ant dist [builds all benchmarks, this is the default]
ant source [builds a source distribution including benchmarks and tools]
ant bm [builds a specific benchmark, bm]
NOTE
A log of each directory is created under this benchmark directory
for benchmark build status and build success or failure files
to be stored. The directory log directory is normally of the
form
${basedir}/log/${build.time}
and contains status.txt where each benchmark build status is recorded,
and either pass.txt if all benchmarks build, or fail.txt if one or
more benchmarks fail to build. Note: that either fail.txt or pass.txt
is created when a full build is performed.
IMPORTANT: before trying to build the suite:
-
Set your
JAVA_HOMEenvironment variable appropriately (it must be set and be consistent with the VM that will be used to build the suite). -
Create the
local.propertiesfile (usingdefault.propertiesas a templcate) -
Set
jdk.11.home, in thelocal.properties, to point to a Java 11 installation.
For more information, run ant -p in the benchmarks directory.
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/ExampleCallback.java for an example).
To run a benchmark with your callback, run:
java -jar dacapo-23.11-chopin.jar -c <callback> <benchmark>
This directory includes all of the source code for the DaCapo harness, which is used to invoke the benchmarks, validate output, etc.

The DaCapo Benchmark Suite conmprises several open source or public domain programs, plus a test harness, some patches to enable the benchmarks to run under the test harness, and a packaging process.
