Transmeta Meets Blades
The Griller writes "Gordon Bell, one of the creators of VAX, and Linus Torvalds were at the launch of a new supercomputing platform at the Los Alamos National Laboratory. Based on Crusoe processors from Transmeta and running a version of linux, it is aimed at being cheaper than conventional supercomputers by requiring no cooling and lower maintenance.
" Basically, it's blade clustering, using Beowulf.
Oh well, here's a list of mirrors...
I've got to wonder why they are using Crusoes. It's a good chip for the application, don't get me wrong... but the last I heard the main advantage it has over StrongARM is x86 compatibility, which shouldn't be an issue here.
=-=-=-=-=-=-=-=-=-=-=-=-=-=-
Friends don't let friends enable ecmascript.
Imagine if these weren't clustered...
Given that you don't need to actively cool these chips, I think what would be even cooler(N.P.I.) is a cube of chips stuck together and interwoven with some sort of vascularized heat-sink. A meaty cluster of 100 chips you can hold in your hand, and plug into a big cube-shaped socket on your supercomputing motherboard. Now *that* would be New for Nerds.
Websurfing done right! StumbleUpon
It all comes down to "power consumption, size, reliability and ease of administration", apparently.
And the marketing people at RLX Technologies should be shot for not having a press release up for this, as it's all based on their product...
The only trick would be getting the things to work properly in a headless configuration -- Apple won't ship them without a graphics card, but I'm relatively certain that you could get a LinuxPPC installation to work even without the card installed.
Wow, so it is true... Linus is a robot.

Why limit yourself to the x86 instruction set when the transmeta processor just needs a new instruction set decoder to emulate pretty much ANY processor? It seems like while they'll be able to use lots of existing software out there, they could get even more performance, efficiency, or maybe just easier programming by using whatever instruction set makes sense for the project.
It's all in the pre-processing with the crusoe, x86 is just there for slideways compatibility and doesn't need to be a limiting factor. When you're using a custom computer, whether it's one or a thousand crusoe processors, wouldn't it make sense to try for some compiler efficiency based on the actual hardware instead of the 8086 legacy?
Using this site as an example to estimate power usage, we get:
240 computer blades in Green Destiny x 6,480 hours uptime (9 months) = 1,555,200 computer hours of uptime
Assuming the only thing changed on the blade is the CPU -- and North Bridge chipset, since the Crusoe includes
a North Bridge on die and the P-III does not -- at full blast the Crusoe consumes about 1.75W of power and the
P-III + NB consumes between 4.5 - 8 W, depending on chip model. However, the 4.5W number is an approximation
from the 0.13 micron ULV P-IIIM chip running in "Battery Saving" mode, or SpeedStepped down to 300 MHz. Running
at full 700 MHz tilt, with NB, we are still talking 5.75W of power consumed.
1,555,200 * 0.0175Kw * 0.10 (dollar per KwH power cost) = $2,721.60 electricity cost/year (Crusoe)
1,555,200 * 0.0575Kw * 0.10 (dollar per KwH power cost) = $8,942.40 electricity cost/year (Intel)
A saving of approx. $6,200/year in direct electric costs.
However, the big savings comes from the heat dissipation of the units. While the newer LV/ULV P-IIIs do not require
active cooling, they still run quite a bit warmer than the Crusoe units. As a result, you don't stick a rack
full of them in a room that isn't temperature controlled. The difference in the air conditioning bill can
easily reach tens of thousands of dollars.
In business, there are two types of money/budgets. One-time grants and acquisition budgets are large chunks of
cash. Recurring expense and operations budgets are smaller. Being able to get a large chunk of cash to BUY a
cluster/supercomputer is one thing. Being able to go back year-after-year and get the funds to keep it running
is another project altogether. $15,000 - $20,000/year for electricity used in running/cooling computers is a
LOT of money to some people. This doesn't include construction or maintenance costs on a custom facility/room.
As far as reduced administration costs go, many conventional supercomputers required chilled water and other
special considerations for operation. People with experience managing things like Sun E15000s and Cray T3Es
are few and far between. They are the last of the "high priesthood" of computer administrators and cost a LOT
of money to employ.
A blade server, on the other hand, is a bunch of x86 computers running Linux -- nothing a couple of grad students
can't learn the ins-and-outs of over a term. Maintenance contracts, spare parts, etc. are also TONS cheaper for
the blade/cluster solution as opposed to high-end SGIs, Suns, Fujitsu and Cray super-computers.
Another site with a bit of good supporting information is

Learning HOW to think is more important than learning WHAT to think.
could someone explain how a microprocessor is administered?
In a large cluster, the question is not whether a processor has failed, but how many have failed. Such clusters generally make it possible to swap out a failed processor while the program is running. Chips that last longer will reduce the dependency on expensive technicians to keep coming in and swapping in new boards.

> Feng also proposed that a new technique is needed for measuring the performance of supercomputers. Instead of looking primarily at how many calculations a system can run in a given amount of time, researchers should also consider factors such as downtime, size, price and maintenance requirements, he said.
Following Feng's lead, the whole supercomputing industry has reacted to this new paradigm shift. Industry leader Cray has ceased development of its upcoming SV2 and has designed a system based on the reliable commodore 64. Explained lead scientist Joel Grey, "We managed to get a C64 computer out of the dump, and bought 1,000 surplus 'Barney' solar calculators off of ebay for $30".
The new system, dubbed the SV64, is not quite as fast as the SV2, but exceeds at new metrics: Converted to run on solar power, and having spent the last 15 years in an uncooled closet continously generating the "experiencing technical dificulties" logo for a local community access TV station, the new computer shatters existing power and reliability records. "With an expected retail price of less than $1M USD, we expect this computer to eclipse [Japanese rival] NEC's lead and become the platform that will be used to perform most of the world's weather, biological, and nuclear simulations well into the next decade", said Grey.
Wall Street analysts pointed out the the system has never needed maintence, nor suffered downtime, nor needed the services of an UNIX system administrater, and as a result, the total cost of ownership should remain low. Shares of component manufacturer Commodore rose 10 points to 10 1/64 in heavy trading today.
