Renaissance Benchmark Suite

The Renaissance Benchmark Suite aggregates common modern JVM workloads, including, but not limited to, Big Data, machine-learning, and functional programming. The suite is intended to be used to optimize just-in-time compilers, interpreters, GCs, and for tools such as profilers, debuggers, or static analyzers, and even different hardware. It is intended to be an open-source, collaborative project, in which the community can propose and improve benchmark workloads.

Running the suite

To run the suite, you will need to download a Renaissance Suite JAR from https://renaissance.dev/download. If you wish to build it yourself, please, consult CONTRIBUTING.md for instructions on building.

To run a Renaissance benchmark, you need to have a JRE version 11 (or later) installed and execute the following java command:

$ java -jar 'renaissance-gpl-0.15.0.jar' <benchmarks>

In the above command, <benchmarks> is the list of benchmarks that you want to run. You can refer to individual benchmarks, e.g., scala-kmeans, or a group of benchmarks, e.g., apache-spark.

The suite generally executes the benchmark's measured operation multiple times. By default, the suite executes each benchmark operation for a specific number of times. The benchmark-specific number of repetitions is only intended for quick visual evaluation of benchmark execution time, but is not sufficient for thorough experimental evaluation, which will generally need much more repetitions.

For thorough experimental evaluation, the benchmarks should be repeated for a large number of times or executed for a long time. The number of repetitions and the execution time can be set for all benchmarks using the -r or -t options. More fine-grained control over benchmark execution can be achieved by providing the harness with a plugin implementing a custom execution policy (see below for details).

Licensing

The Renaissance Suite comes in two distributions, and is available under both the MIT license and the GPL3 license. The GPL distribution with all the benchmarks is licensed under the GPL3 license, while the MIT distribution includes only those benchmarks that themselves have less restrictive licenses.

Depending on your needs, you can use either of the two distributions.

The list below contains the licensing information (and JVM version requirements) for each benchmark.

  • dummy-validation-failing - A dummy benchmark for testing the harness (fails during validation).
    Default repetitions: 20; MIT license, MIT distribution; Supported JVM: 11 and later

If you are using an external tool to inspect a benchmark, such as an instrumentation agent, or a profiler, then you may need to make this tool aware of when a benchmark's measured operation is about to be executed and when it finished executing.

If you need to collect additional metrics associated with the execution of the measured operation, e.g., hardware counters, you will need to be notified about operation execution, and you may want to store the measured values in the output files produced by the harness.

If you need the harness to produce output files in different format (other than CSV or JSON), you will need to be notified about values of metrics collected by the harness and other plugins.

If you need more fine-grained control over the repetition of the benchmark's measured operation, you will need to be able to tell the harness when to keep executing the benchmark and when to stop.

To this end, the suite provides hooks for plugins which can subscribe to events related to harness state and benchmark execution.

This repository contains two such plugins: one that uses a native agent built with PAPI to collect information from hardware counters and a plugin for collecting information from a CompilationMXBean. See their respective READMEs under the plugin directory for more information.

If you wish to create your own plugin, please consult documentation/plugins.md for more details.

To make the harness use an external plugin, it needs to be specified on the command line. The harness can load multiple plugins, and each must be enabled using the --plugin <class-path>[!<class-name>] option. The <class-path> is the class path on which to look for the plugin class (optionally, you may add <class-name> to specify a fully qualified name of the plugin class).

Custom execution policy must be enabled using the --policy <class-path>!<class-name> option. The syntax is the same as in case of normal plugins (and the policy is also a plugin, which can register for all event types), but this option tells the harness to actually use the plugin to control benchmark execution. Other than that, policy is treated the same way as a plugin.

When registering plugins for pair events (harness init/shutdown, benchmark set up/tear down, operation set up/tear down), the plugins specified earlier will "wrap" plugins specified later. This means that for example plugins that want to collect additional measurements and need to invoked as close as possible to the measured operation need to be specified last. Note that this also applies to an external execution policy, which would be generally specified first, but any order is possible.

Plugins (and policies) can receive additional command line arguments. Each argument must be given using the --with-arg <arg> option, which appends <arg> to the list of arguments for the plugin (or policy) that was last mentioned on the command line. Whenever a --plugin (or --policy) option is encountered, the subsequent --with-arg options will append arguments to that plugin (or policy).
