Gephi is a cross-platform application, as it is developed in Java. It was successfully tested on many different architecture, OS and graphical configuration. Gephi requires Java version 6 and later, get it here.
Minimum hardware requirements
500 MHz CPU + 128 MB RAM + OpenGL 1.2
There is no absolute minimum. This is a practical minimum. Performance is a function of graph size.
(nodes + edges)
Note that Gephi has been successfully tested on Netbooks, running on Intel® Atom.
Gephi uses an OpenGL 3D engine to speed up graph visualization. However a compatible graphic card is required. If your graphic card is older than 5 years, or if your laptop doesn’t have a dedicated graphic card, you may have to upgrade your hardware to run Gephi.
If you’re running on Linux, get latest vendor graphical drivers to ensure OpenGL hardware acceleration.
JavaThe current stable version of Gephi will only run with Java 6 or 7 (i.e. not Java 8) on both Windows and Linux. On Mac OS, it works with Java 6 only. See the installation instructions.
Mac OS X
Java 1.6 is unfortunately only available on 64-bit Intel Macs. The community is waiting for a full 1.6 support.
For Macs that can have Java 6, see how to enable it: Install Java 6 on Mac OS X Leopard
Note that Soylatte/OpenJDK isn’t supported.
