DrQueue is an Open Source render farm managing software. It distributes shell based tasks such as rendering images on a per frame basis. DrQueue works under Linux, FreeBSD, Irix, Mac OS X and Windows. It is distributed under GPL and is composed by three main tools: master, slave and drqman.

DrQueue is fully scriptable.

The master acts as a server, where all tasks are stored and where computers running slaves report their success or failure executing the tasks.

The slaves run on every node of the render farm. They inform about their load average and if it is below some level (determined by the user) they are considered available for rendering. Then they take the first task asigned by the master server.

drqman is the GUI used to control jobs and computers. You can reprioritize jobs, stop them, restart specific frames, change frames to be rendered and so. drqman uses gtk as widget library.

Right now DrQueue supports Maya, Mental Ray, Blender, BMRT, 3Delight and Pixie under the GUI. The other tools need a small shell script to be written.

DrQueue has been tested in production environments and has proved to be a stable alternative to other comercial products with the advantage of being licensed under GPL.
