WETA’s Processing Power for AVATAR

Information Management has some new information to add to yesterday’s data about the power of Weta, including details of the cooling, queue management, and frame render times involved in Avatar.

The queueing system is a Pixar product called Alfred, which creates a hierarchical job structure or tree of multiple tasks that have to run in a certain order. In any single job, there might be thousands of interdependent tasks. As soon as CPUs on the render wall are freed up, new tasks are fired at idle processors.

At the peak of AVATAR, Wilkie was wrangling more than 10,000 jobs and an estimated 1.3 to 1.4 million tasks per day. Each frame of the 24 frame-per-second movie saw multiple iterations of back and forth between directors and artists and took multiple hours to render.
