Own a Piece of An Apple-Based Supercomputer
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."
I wish there was some kind of engraving on the aluminium casing stating something like "Virginia Tech, Supercomputer node #758 - 2003" Then they could definitively sell it at a Premium. I mean I can get this kind of computer off ebay for more or less the smae price. I need some kind of souvenir that it's from Virginia. How about sending it through the IPOD engraving shop?
Artificial intelligence is no match for natural stupidity
As someone else noted, if they were engraved or etched or something that would make them special.
This is an educational and research establishment, not a commercial enterprise.
/.) that Virginia Tech would have sold the units to students, freshmen, whatever, at a knock down rate. Or even used a ton of them within the university itself.
You'd have thought (as some students were hinting here at
Yet more profiteering from a supposedly educational institution.
VT isn't the one selling these systems... Apple is. VT is tossing them back at Apple for shiny new Xserves. Apparently being the 3rd fastest computer in the world isn't good enough anymore.

I was a bit confused by the decision to include Firewire in this machine. I know it is an apple kind of penchant, but surely a server won't need firewire.
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.
on the contrary. My 4 years experience with clusters show that after the first two months of burn-in where many components fail, you aftewards have a higher MTBF than with PCs used "normall", because in the Beowulf case the AC power is regulated, the machine is almost never switched on and off (major cause of damage because at startup every component consumes power at the same time, voltage drops, and damage occurs), temperature is kept constant, the machine is kept in a safe room where nobody ventures more often than once a week because of the cold and the noise, therefore there is no dust in the machines or grease on the contacts.
Google passes Turing test : see my journal
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.
Life is short: void the warranty.
oo..damn.. it was!
Why oh why do companies use mail in rebates?
so they can stick low price tags in big numbers on the shelf. That's gotten me a few times - you see, "Oh, an X for only $19.95!" so you take it up to the counter, and the cashier rings you up for $39.95 - often by then the consumer is already psychologically committed and just pays it. It's a common tactic, rebates are just one methode of exploiting consumer naivety. Bottom line is, it generates more sales.
try { do() || do_not(); } catch (JediException err) { yoda(err); }
The G5 was the clear winner out of all the chips on the market, and Apple was the clear winner of the platforms considered, and they considered *ALL* of them worth considering.
The success of the venture simply proves the superiority of keeping an open mind and not bringing tired old pre-conceptions (Apple's slow, Apple sux, etc.) to your work.
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.
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 all 0s and 1s. Or it's not.
Virginia Tech wanted Xserves in the first place. Apple didn't reveal them until January. Look at the benefits. 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.
No VT needed the PR probably more then Apple now they get grant money out the wazoo
Please don't begrudge us this. Virginia's state legislature has cut over 28% from our 2002 level of funding, while just recently passing laws which effectively cap tuition hikes at about 5% per year. My tuition has gone from $1500/semester (2001 in state) to almost $2200/semester (2004 in state).
And please don't respond with "blah blah, if they used the money more effectively". We're up against the wall here. About 5 professors in my department (History) out of 25 or so have been laid off, or sent on research sabbatical so that they don't have to be paid. We've fired over 1/2 of the maintenance staff, and people on campus no longer have trash cans in their dorm hallways - they have to take their trash outside to a dumpster. The snow trucks in Blacksburg have far less salt than they had last year to clear the roads (I only think of this as I sit here at Netmar and watch today's 3 inches of snow fall). I now this isn't grave hardship, but seriously, we've cut about everything we can.
The supercompuer gives us both grants and positive PR. Students see that, despite the state of the economy, we're trying to push to the top of research institutes. We're trying to push ourselves above 67th (or whatever) on that college engineering school ratings, trying to compete with our neighbor down interstate 64, who, for no discernable reason, has an engineering program with the inflated ranking of ~ 15th. And yes, we get grants from the government and money from private industry in exchange for timesharing on the bigmac.
Just let this one go. We need the money, the BigMac has not only made us money, but has raised awareness of the university. It's a good thing.

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.
Why is it that the proponents of "one nation under God" are so eager to get rid of "liberty and justice for all"?
Just called, no need to call.. they're all gone.. shucks.
