Link of the week - Kung Fu Panda digs grids


Using grid computing, digital artists working on Kung Fu Panda are performing 75,000 to 100,000 batch-processing jobs each night, each ranging from a few minutes per frame to 15 hours per frame, depending on the rendering complexity of the digital frame sequence.

Grid computing isn't always about saving the world. It can be about creating a new world, in this case, the world of the Kung Fu Panda, a new animation feature by Dream Works to be released in June.

Creating animation films like Kung Fu Panda typically requires around 25 million render hours from start to finish. The Dream Works computer farm comprises a 4000-processor Linux cluster, but when their digital artists are all simultaneously pinging the compute cluster to retrieve digital frame data, the system's input-output comes under a lot of strain.

Enter grid computing, in the form of Ibrix parallel file server software. DreamWorks added Ibrix to its animation system about six months ago, aiming to accelerate their high-resolution lighting and rendering applications by up to five times.

Ed Leonard, DreamWorks chief technology officer, said that he expects the grid technology to become a fixture for all future DreamWorks Animation films. The studio releases at least two films every year and is generally developing 10 different animation features at a time.

Scenes that once took two hours to create are now completed in seconds, Leonard said. "That's pretty remarkable, and we're scratching the surface on where we are going with this," he said.
