Graphalytics OpenG platform driver

Getting started

This is a Graphalytics benchmark driver for OpenG. Please refer to the documentation of Graphalytics core for an introduction to using Graphalytics.

• Make sure that you have installed Graphalytics.
• Download the source code from this repository.
• Execute mvn clean package in the root directory (See details in Software Build).
• Extract the distribution from graphalytics-{graphalytics-version}-openg-{platform-version}.tar.gz.

The following dependencies are required for this platform driver:

• GraphBIG (make sure to checkout the graphalytics branch)

Download GraphBIG and unpack into any directory. Modify platform.openg.home in config/platform.properties to point to this directory or set the environment variable OPENG_HOME to this directory.

OpenG-specific benchmark configuration

Edit config/platform.properties to change the following settings:

• platform.openg.home: Directory where OpenG has been installed.
• platform.openg.intermediate-dir: Directory where intermediate conversion files are stored. During the benchmark, graphs are converted from Graphalytics format to OpenG csv format.
• platform.openg.num-worker-threads: Number of threads to use when running OpenG.

Running the benchmark

To execute a Graphalytics benchmark on OpenG (using this driver), follow the steps in the Graphalytics tutorial on Running Benchmark.
