Keroyokan is OpenSource distributed rendering engine that works on Blender, the name of keroyokan is taken from javanese language that mean working together without any rasial issue. Keroyokan has release their first version with codename "kuniran" which tested and running well on both Linux and windows as node or master.

A render farm is a computer cluster built to render computer-generated imagery (CGI), typically for film and television visual effects, using off-line batch processing. This is different from a render wall, which is a networked, tiled display used for real-time rendering. The rendering of images is a highly parallelizable activity, as each frame usually can be calculated independently of the others, with the main communication between processors being the upload of the initial source material, such as models and textures, and the download of the finished images.
