Virginia Tech Upgrade: PowerMac G5 to Xserve G5

An anonymous reader writes "Virginia Tech officially announced that they will be migrating their G5 Supercomputer from PowerMac G5s to Xserves. According to the article, the Xserve G5s will reduce power consumption, heat production and decrease the system size by a factor of three. The pricing of the upgrade is still being determined, and according to Srinidhi Varadarajan, they are working on getting "very good homes" for the PowerMac G5s which will be replaced."

      Still, unless Apple gave a substantial incentive, it seem extravagant to purchase 1100 G5s and the tower accommodating racks to house them, only to upgrade them a few months later.

      Also, a savvy Slashdot reader, leaked the plans some time before the upgrade was officially announced.

    When it was first rumored that VT might replace its G5 boxes with Xserves, a friend of mine shared the idea that the pulled machines should be resold to the public, with some indication that they had been part of the cluster, perhaps a plaque or laser engraving noting that they had been included in the VT supercomputer. I bet those things would be bid up sky-high on eBay!

    While providing no real speed improvement this should actually speed up the cluster by a factor two - The XServe G5s have error correcting RAM in which should stop them having to run jobs twice just to be sure of getting the right result. They may even get a slight speed boost from having a 1.1Ghz bus rather than a 1Ghz one.

      ECC checking only adds a single clock cycle on reads and imposes no additional delays on writes since the ECC generation executes in parallel with other tasks. This delay only matters for the first cycle of a transaction; adding to the overall first access latency. The rest of the data transfers are pipelined so no additional delays are incurred. For well designed memory controllers(SDRAM,DDR) FAL is ~13+ base bus clocks for poorly designed ones ~17+ base bus clocks. 4-8% percent degredation in overall system performance is not likely(perhaps a single test can show this).

    It may seem like a waste to upgrade a system only four months old, but the reduced power consumption will save some dollars in the long term. By ditching the towers, they also save a boatload of space...

    Absolutely an impressive school. 10 years ago, they were a joke. Now they built a national reputation via their football team, so people have heard of them, and projects like this put them on the map. When I looked at schools, they never entered the equation. If I was looking at engineering schools today, I'm sure that I would end up applying there.

    This is a school with great self promotion and is going to go places. Unlike places like MIT, they don't sit on their Laurels, they are exploding.

    I expect that in 20 years, they'll be considered one of the elite engineering schools. Kinda neat to have your college degree appreciate in value because the school gets better. I can't imagine that you don't get a decent engineering education at any engineering focused school, and this research project is a brilliant PR stunt.

    What I never understood is why someone like IBM didn't come along and cluster 10,000 dual P4 nodes together for fun to get on the top spot. I'm sure they have the inventory to write that off.

    That would be ASCI White, which is currently #8 on the top 500. It's an 8192-cpu Power3 machine, and they didn't do it just for fun. It was #1 on the top 500 in Nov 2000.

    Also, #10 on the top 500 is a 1920-node IBM Xeon 2.4Ghz cluster, but why should IBM use Intel processors when they make their own?

    ...how loud the Xserves are compared to the G5's? I can't imagine the decibels in a room full of them. One thing they don't mention in the article, and possibly another reason to upgrade to the Xserves, is the use of the Server Manager software. This software doesn't work on the PowerMac G5's because it doesn't have the sensors built in that the Xserves do. Not being that keen on cluster arrangements, I wonder if they have another product in place now that does the same thing with the PowerMacs?

    Correct me if I am wrong, but I thought that Steve Job's himself had already said this in his Macworld Keynote. An excerpt from someone's notes:

    Jobs talks about the G5 processor and Virginia Tech SuperComputer, who wanted "the first" 1,100 dual-2GHz Power Mac G5s. ("We pissed off a few people" getting them the first ones.") Cost them only $5.2 million and sending ripples through Supercomputer world. Jobs shows Virginia Tech Supercomputer video. It uses Infiniband networking; it took less than 3 weeks to assemble. Now in the top 3 Supercomputers. First academic machine to break the 10 teraflop barrier. The entire system runs on Mac OS X. Jobs says he expects to see a few more [Supercomputers] popping up hear and there

    So VT is probably going to be THE FIRST to recieve G5 Xserve's.

    Space is finite, so reducing your space needs by 2/3rds and reducing your expensive air-conditioning budget by some amount is actually a huge argument in favor of upgrading. The Xserves are cheaper cycle for cycle than the Power Mac G5s, too.

    The other issue: with 2/3rds of your space free, you can wait for faster G5s to appear and slot those in with very small amounts of disruption. Or a grant comes through for a $1,000,000 for more computers -- boom, you're done. No lengthy process of finding more space, spending more to build out a/c, etc.
