Rent A Bit Of Weta Digital

Posted by timothy on from the route-bits-through-mordor dept.

An anonymous reader writes linking to this story at stuff.co.nz, excerpting: "Five hundred powerful computers used by Weta Digital to help create the special effects for the Lord of the Rings may be put up for hire.... The pizza-box sized IBM blade servers each incorporate dual 2.8 gigahertz Intel Xeon processors and 6 [gigabytes?] of memory." Update: 03/22 07:08 GMT by S : The linked story says 6 megabytes of memory, we don't believe 'em.

    the real killer is that there's quite a few industries that can't rent time on their cluster because the gigabit interconnect ( IBM blade chassis have a switch module internal to each chassis, and I don't think you can get any HSLL - high-speed, low-latency - network interconnect modules ( Myrinet, SCI, Quadrics, etc. ) for them ) has too high of a latency for their applications.

    Bandwidth-wise they should be fine, as each chassis has at least four ports that could be trunked to a top-level switch w/ a beefy backplane ( I could tell you the # of ports per chassis if I was at work, as I've been messing w/ some of their blades lately ), giving a peak per-chassis bw of > 400 MB/sec.

    Of course, I'm wondering how Weta got around it themselves, as I would think that rendering digital video is fairly heavy on inter-node communication. This would still be aswesome for web-servers or problems that are "embarassingly parallel".

      Rendering digital video is about as parallel as compute loads get. Generally each frame can be an independent computation. For most ray-tracing algorithms, computing each pixel of each frame is fully parallelizable too.

      The global AI things they did to have 10,000 troops all interacting together is obviously not quite so independent, but I'm willing to be the bulk of the compute load goes into creating pictures of those interactions, not the interactions themselves.
