Pixar Eclipses Sun with Linux/Intel
lieutenant writes "Pixar Animation Studios is replacing servers from Sun in its render farm with eight new blade servers from Rackspace. In all, the blade system contains 1,024 Intel 2.8GHz Xeon processors, and it runs the open-source Linux operating system. Pixar has ported its Renderman software to run on Linux." I'd love to see their electric bill ;)
If you have a task that can be easily partitioned off (oh like each individual frame would be an easy break for this) you can send each task to a different machine allowing you to parellelize the task.
This is a poor mans version of NUMA (Non Uniform Memory Access) created and popularized by Sequent (now a division of IBM) where rather than have a single pool of addressable memory, you have multiple pools of memory, some with very fast access, some with slower.
What I am wondering is what do they do for the cluster cross connect. In large scale cluster environments, this tends to be a significant bottleneck. In large scale clusters you start seeing things like HIPPI, VIA, and soon to be Infiniband... wonder what this is stocked up with
I have mod points and I am not afraid to use them
As far as I know Rackspace is a managed hosting company. Rackable Systems makes servers - Yahoo and Google both use them. Anyone know if the article has it wrong, and Pixar is actually using Rackable machines?
They have half-depth 1U boxes. That's right, two servers in 1U, back to back.
Includes space between the two for cabling and cooling.
They specialize in delivering easy to manage (physically) racks of highly commoditized systems.
(I work with them in a reseller relationship)
Imagine a 71U rack(minus 1U for a switch), with 142 boxes, all dual proc. 248 procs in a rack!
Man, I wish they'd put the right link in there.
Striving to achieve a lower state of conciousness
I recently attended a talk by Google's chief engineer. They have approximately 15,000 x86 machines running Linux at seven data centers in the United States.
Weird failures occur so often, such as disks returning garbage without the controller informing the OS, that Google does a checksum on _every_ data structure in their user-level software. He also talked about how Linux is good enough for them, but it doesn't perform well with respects to I/O under heavy load. He says they like Linux because they have the source-code and that they minimize excessive I/O loads on their machines. Nobody asked why they don't use FreeBSD but I suspect its because Linux has better hardware support and Google builds their own machines with numerous different components based on the latest technology.
Sorry Guys... This article looks to be a bit off base!
/. I though you guys did better about checking this kind of thing out! Just because it's on c-net doesn't mean it's accurate. Well kudos to who ever really got this job.

I work for Rackspace Managed Hosting. The company the link "Rackspace" references in the C-Net article. This kind of cluster is not consistent with our business. We are most focused on web-centric managed hosting vrs colocation. A rendering cluster is something that, from my experience, we've never done. Also We don't carry Blade servers. C-Mon
