Drooling Over VA Tech's 1100-Node G5 Cluster

Mr. Slurpee writes "Virginia Tech's 1100-node dual 2 GHz Apple G5 Terascale Cluster is getting racked up and ready to roar.

Hm.

What I really would like to know is how they install and configure all those machines. Their method of doing that will be very useful for even the (relatively) smaller networks that don't necessarily have to be clusters.

For example, I've yet to figure out a way to effectively get a computer lab with 30 eMacs installed and configured the same way. DHCP/Netboot is slow because we only have 100mbit switches. Split CD images are slow, and Jaguar doesn't yet have free software that does that yet (besides the dd of course). I'm not sure how to keep them all updated either.

I really hope they describe how they maintain the operating system on them.

- It's pretty clear to me that Apple didn't divert anything. If you look at the numbers, the VT order accounts for about 1% of all Dual G5 orders. That's hardly enough to cause the delays that people are seeing in their ship dates. Notice the slide states Apple offered an "early september" ship date, but Apple initially promised customers a mid-late August date. Given when those talks between VT and Apple were likely taking place, that means that Apple had intended to fill other orders first, and had a special allotment for the VT order.

- I don't know a whole lot about a blade center, but there doesn't seem to be a place to plug in the high-speed interconnects. Also, it runs on Intel chips that run hotter and do less work than the G5, especially when AltiVec gets involved, which is usually why you build a computer this size; vector processing. I'm also guessing the required configuration needed resale value to students at the end of life for the project/system.

- That's absoloutly true. When you need technical details about Linux you have to dig. When you have a question about OS X's guts, I'd guess you call Apple and have a conference call with all the coders (at least at this level of purchase/prestige). Could you imagine trying to get Linus, and all the other code writers for Linux and the supporting libraries and utilites on the phone at once?
