Drooling Over VA Tech's 1100-Node G5 Cluster

    Using full sized cases seems like a rather inefficient use of space to me. But I guess those cases are all fairly full - the heatsinks in those things are enormous. Wish PCs had heatsinks like that, then maybe mine wouldn't be so noisy.

    They've got 1100+...where's mine? I ordered a Dual 2.0 GHz G5 in July....still no sight. Supposed to ship on Tuesday....but online time will tell....

    I haven't actually tried it yet since I don't have access to enough Macs, but I imagine it's something you would start and let happen overnight... I mean, that's more or less how Apple does it in their own stores, wipe and restore overnight, I think. Or at least after the store closes and before the next opening day.

    If you had the choice of building a supercomputer for your school then would you use brand name inexpensive processor like AMD or expensive chips like G5's or Itaniums ?

    I really don't get what you can get out of a single fancy expensive processor when a couple of less expensive chips can do the job .

      Reliability.
      No one in their right mind would try to argue that one couldn't build a home-grown system for less. But with optical ports? FW 400 and 800? Gigabit ethernet? USB 2.0? And with said home-grown machines, when the NIC goes bad in one, or a memory slot goes bad in another, who do you call? The NIC or mainboard manufacturer? So you what, keep a list of all your machines, give 'em i.d. numbers or whatever, itemize the guts and who made what (mainboard, NIC, RAM, CPU, HDD, etc.) of each, and hope to make sense of it all when stuff starts to fail? Me, if I was in charge of it, it would make sense to me to farm it all out to one company, and then when something breaks there is one number that I have to call.
      Also, lets not forget that this is probably going to be used for research, and if it involves vectors, then AltiVec is the SIMD for you.

      Of course, being human, my opinion is suspect.

      With an Open Source program, you don't NEED to get to talk to the original programmer for any reason at all. All you need to do is hire your own programmer to go through the code, and understand it. Then when a question arises, you can simply refer to your local expert, or look through the code yourself to locate the problem.


      Hrm, this same logic should apply to medicine, cars, houses, and just about anything else that we as people have access to Original Source... yet notice how as a society and culture we tend to specialize and rely on experts?

      I would be that, due to economics and division of labor, it is more productive and cost effective for VT, and many other places, to rely on a third party (IE Apple or Red Hat) to support their OS, while they themselves support, say, their business/product/venture... in this case, VT's research, while Apple supports the hardware/software. Makes sense, doesn't it? Each party does what it does best, so that the end result is more spectacular than if VT decided to, I dunno, devote resources to replicate what Apple already knows. Or at least has the resources to know.

    That's because there is no such thing from Apple yet. Given the serious engineering that obviously went into the G5 case, I don't think we can assume that they can just drop a G5 into a current XServe and sell it.

    Plus, these guys were on a pretty strict deadline, the cluster has to be functional by November IIRC. So, they wouldn't have wanted to wait any longer than they did.

  9. Re:Small Schools by YouHaveSnail · · Score: 3, Insightful

    It doesn't take pull... it takes money. Small schools have other significant advantages.

    When you choose between going to a large, research-oriented school and going to a smaller school, you're essentially making a trade-off between resources and personal attention. Bigger schools have more and deeper resources, but it can be tough for undergrads to have much significant interaction with professors, particularly in the first year or two. Smaller schools may not offer the same variety of courses, or get huge research funding, or field a championship football team, but as an undergrad your chances of not just interacting with but really getting to know the faculty members (and not just the ones in your major department) are much better.

    Most schools are happy to collaborate with others, so if you've got an idea that you think is well suited to Virginia Tech's cluster, talk to your advisor about submitting a proposal to VT. If it really is a good idea, your advisor may help you refine it and ultimately turn it into a research project.

    I don't understand why people still continue to build large clusters with footprint style cases. We have a linux cluster here at Purdue built from standard off the shelf cases / components. It takes up so much space, it frequently gets mocked. Especially now, we've since built smaller clusters using Dell 1U rackmount servers that take up 1/10 the space with ten times more computing power. Bigger is not always better.

    Except VT isn't going to be running SPEC[int|fp]+[_rate]*2000, so optimizing against those benchmarks isn't sufficient.

    When all is said and done, it's been shown that for many vectorizable programs, Altivec still spanks SSE/SSE2/3d!Now, and anything else offered in the commodity market. Couple dual 2GHz G5s with Altivec and IBM's XLC autovectorizing compiler, and I think VT probably does have quite a powerful machine, more so than SPEC scores can quantify.
