Own a Piece of An Apple-Based Supercomputer 296

Posted by simoniker from the tremendously-historical dept.
Graff writes "Now that Apple has come out with the Xserve G5, Virginia Tech has been swapping out parts of their 'System X' supercomputer for the more compact 1U Xserves. MacMall is selling some of those System X component G5 systems with an approximate $200 savings and an extra 512 megs of RAM over a normal G5. You can read more about it at MacCentral."

Smaller case, less heat generated, less power consumed, error corecting code memory; all things which would be extemely useful in a supercomputer like this. From what I have read, the upgrade will use 25% less power and take up a third less space. If I were Tech, I would throw the current G5s back too.

                Well, from what I can see there is barely any difference between the memory controllers on the two systems. It looks like it was just a new revision of the same ASIC. Apple doesn't exactly provide many details on this, but it looks like the new memory/processor controller chip would be a drop-in replacement for the chip used on the original Powermac. Therefore it's possible (even likely) that they will use this new revision on the next revamp of the G5 line. In fact, they could well start slipping them into the current line-up without telling anyone about it.

                I don't anticipate that Apple will sell any desktop G5's with ECC memory installed at the factory, but if the memory controller supports ECC you could easily replace the factory memory with third-party ECC memory.

            You are 100% correct. In a big server farm, space, heat, and power consumption are major concerns. Assuming your figures are correct and the replacement hardware has similar specs to what they are replacing, they can improve the overall performance of the system by at least 25% at the same power consumption, not counting the additional power savings that would see from the lower heat load. Less heat also translated directly into longer life.

            I'll admit that a 6-month replacement cycle is pretty short, but it actually makes sense because they're avoiding the worst of the depreciation. I'm not up on used Mac prices, but x86 server hardware depreciates around 50% per year (refurbished 2 year old x86 servers routinely sell for around 20% - 30% of their original price; refurbished 3 year old gear sells for well under 10% of it's original price. You can get a maxed out Quad processor P-III server for well under $5000 which cost $50K when new.

            That said, I don't think that this is a good deal. $200 savings on a $3000 box is only a 6.7% discount for 6 month old hardware; a 20% - 25% discount would be more in line with current market.

            • I think Mac hardware depreciates more slowly than PC stuff; there's not quite the same desperate impetus to have the very latest hardware, probably because people tend to buy Macs to do work rather than play games.

              In my experience the price of Macs depreciates far less with time than your standard x86 boxen.

              First of all, buying a new Mac is generally expensive.

              Secondly, Apple's computers are generally made with solid, high-quality components and last a long time.

              I just sold a single-processor G4/450Mhz Sawtooth for $400 the other day: that's a 4 year old machine that cost about $2000 new, yet can still be sold at %20 of original price.

      • I'm going to have to disagree with you concerning the amount of wear and tear.

        Most computers fail either in the first month or so of use or after many years of good use. In the first case it's usually a bad component that slipped by quality control. In the latter it is simply the ravages of time. Longer quality control "burn-in" times would eliminate many of those first month failures, but the vendor really doesn't have the time/space for long burn-ins.

        Now, the Number One way to shorten the life of your computer is to turn it on and off frequently. The computer heats up when you run it and cools when it's off. The expansion and contraction of components associated with these temperature changes stresses every solder joint on every component -- and may even stress the chip-level components themselves. To lengthen the life of your hardware (at the cost of extra electricity), leave your system on unless you aren't going to be using it for a significant length of time (i.e.: don't power cycle more than once a day).

        These G5's have been on for approximately six months straight in a very well-controlled temperature environment. This is a burn-in that virtually guarantees that there were no manufacturing defects. However, since they weren't power-cycling on a regular basis, it was actually a VERY low-stress environment.

      I'm fairly sure Virginia Tech wanted the 1u cases all along (makes more sense). However, they needed the cluster up in time to make the Top 100 list. Being on that list brings in _lots_ of research money. So yes, they did need them.

    • Gee, thanks for doing this after delaying my order for 6 weeks back when the G5s were originally supposed to be shipping to the rest of us.

      Six weeks? VT neeeded 1100 machines. Apple shipped 220 000 G5s the first quarter. 0.5% of all machines went to VT. That ammounts to appoximately half a day of delivery delays.
      • Apple redirected G5s that were originially scheduled to fulfull pre-orders to VT, resulting in (at least) 1100 people, who'd placed preorders and been promised a ship date, being out of a G5 and having to wait till a second ship (which may very well have been 6 weeks, I dunno).

        It grates on people being told that they're less important than a PR move.

    • They wanted to place highly in the top 500. The top 500 runs in "sweeps," meaning they have to be up and running on the DATE when the results are calculated. I don't know how often the sweeps are run -- ever 6 months or year or so.

      So they most certainly WERE in a hurry. Now they can swap them out for more space-efficient Xserve G5's (and maybe gain some more speed with the extra space).

      I believe that the Apple recommended restore procedure for an XServe involves booking from a copy of the OS installed on your iPod (which connects via FireWire).

      You're more likely to back up onto tape.

      There's no reason why you can't plug the tape drive in over FireWire. FireWire is basically a serial variant SCSI (okay, I'm oversimplifying a bit here) and with speeds of up to 800Mb/s it's fast enough for most things. You probably wouldn't want to connect your RAID array via FireWire, but for backups it's plenty fast enough. Many tape drives only let you write at Oh, and by the way the G5 units they are selling are intended as workstations not as servers (hence the digital audio out and the Radeon 9600 Pro, neither of which is really required for a server).

      Actually there are lots of reasons to include firewire on a server.

      - You can hang a firewire mass storage device off of it to backup (tape, disk, etc), boot from (recovery, etc), add extra storage in a pinch, etc.

      - You can create various types of clusters using firewire. One product is the sancube.

      - It's cheaper to design in a feature that may not be used in one incarnation of a product, but may be usable in others. Case in point your comment about Audigy sound cards on high end Intel servers, those very same motherboards are probably used in both servers and high end workstations, no point in having two different motherboards just to save a few pennies off of a $500+ mobo.

      First of all, how is this profiteering? They are trading in their G5s to upgrade their cluster, Virginia Tech is not selling the "old" ones, MACMALL IS! Virginia Tech is simply trading them in. So you would rather have Virginia Tech eat all the money that they spent to purchase the original lot of 1,100 instead of making them look much better to potential customers who want to purchase the use of their cluster, by leveraging the money they have already spent? It is in business to make a profit, like it or not, it is not their primary main objective (Chinpokomon!) but it can not be ignored, either. I respect your opinion that some of the G5s should have been kept around for use in labs, by students, etc. Then again, we don't know if VT traded ALL of their G5s, they just might have kept some for the uses that you and I laid out. I suppose this just shows, on a grand scale, the high resale value of Apples!

    Apple's online store is charging $2399 for refurbed dual G5s, and the student store's price for a new dual G5 is $2699, $100 less than the MacMall refurbs from Tech. You can even take $26 more off for getting rid of the internal mode, which the supercomputer refurbs don't have either.

    Even if you add the extra 512 megs of RAM from Apple's site (where prices aren't the best), these Va Tech refurbs are only $100 less than what a student would spend on the same box new. Not to mention these 2 GHz duallies are rated as "Buy only if you need it - Approaching the end of a cycle" on the Macrumors buyers' guide page [macrumors.com].

    So not a deal at all if you're a student (though I have to think students at Va Tech could get the inside track on the boxes -- anyone know?) and not a great price for a refurb if you're Joe Schmoe. And not a box with great longevity, relatively speaking, either, if Macrumors has the lifecycle pegged.

    Wait for a processor speed bump unless you're dying to own a little bit of celebrity.

      It's not like the machines are going to stop working or anything. It's just that the rumor mill has Apple about to roll out speed-bumped G5's.

      I say this is a sweet time to pick up a dual 2 Ghz G5. Given the speed increases the rumor sites have been talking about (like 200-400 Mhz more) the new systems are not going to be that much faster than the current ones so the lower price is a win for someone lo

    • Interesting page. I'd say that your guess is probably right. I think Jobs did promise 3GHz G5s sometime mid to late 2004. For all we know, Big Blue is stockpiling some 2.5GHz rated chips right now.

    Looking at the specs of those machines, it seems that there is a Radeon 9600 in every G5. Now I know that OS X takes advantage of 3D hardware, but as a server, this is almost a wasted expense, especially considering the number of servers that they bought.

    What would be spiffy if there was a way that they could do SOME of the math on the GPUs. I never saw a product that could do that, but it would be rather fast. No?

    • Ok, everyone keeps calling these servers and wondering why they've got firewire and a nice video card. Apple sells XServe's if you want a pure server. Typically, these machines would be used by some media professional (layout, design, audio, movies, animation) for which these things make complete sense. These aren't XServe's, these are PowerMacs and as such should be loaded to the gill.

      VT didn't buy XServe's to start because there was no G5 version. Now that there is, they are, which over the long run

    • There actually IS a way to do math on GPUs, take a look at what these people are doing [gpgpu.org]. I don't know if there is any software yet that will run on Macs and OS X, I think most of it is targeting PCs running Linux, but at least in theory you can do some some pretty high performance math on GPUs.

      Of course, there are some downsides to this. First off, it only works on the latest and greatest generation of GPUs that are programable (the Radeon 9600 should qualify here). Second, GPUs only support single-prec

    There is a lot in these machines that a clustered supercomputer setup REALLY doesn't need. One article i read about this said the VT designer wanted to buy the chips right from IBM initially. It came down to the PowerMac G5 being the ONLY way to get those chips at the time. I guess when he made his pitch to Apple they either would not say when they expected to ship Xserves, or they were worried about looming supercomputers. i also read elsewhere that in the next year or so there are a few other massive machines that will be coming online and it's possible they would fill up the top 5. it came down to timing where a $7 Million setup could land in the top 5 machines up against machines costing 20 times as much.

    anyway if you look at the specs you can see all the silly stuff.... that cluster does not need 1100 Superdrives, or 1100 Radeon 9600 cards..... let alone size and whatnot... i'm sure it was done because the Xserves were just too far off and it was the only machine out there with the G5/970 chip for sale to anyone.

    look at the specs:


    The systems sold by MacMall are listed as 2.0GHz Power Mac G5s equipped with 1GB DDR SDRAM (2 512MB memory cards); equipped with 160GB ATA drives, a SuperDrive, ATI Radeon 9600 Pro graphics processor, Gigabit Ethernet, 3 USB 2.0 ports, 2 USB 1.1 ports, 2 FireWire 400 ports and 1 FireWire 800 port, along with an AirPort Extreme card slot and no modem -- in other words, a stock Power Mac G5 Dual 2GHz system with a memory upgrade from 512MB to 1GB


    it does seem the pulled the fibre cards out... they are optional in Xserves... maybe they just swapped those? i don't know if they are the same in both machines normally.

    • Umm.... the G5's that were being built for normal use had what VT needed. To order specially built G5's would have pushed back delivery while either special ones were built or the supposedly superfluous parts were removed from G5's rolling off the normal assembly line; either option would have also increased costs and reduce eventual value.

      Even if the new XServes weren't ready for another year, it's obvious that eventually these computers would be broken up and replaced. If they are full-functioning G
