Big Mac Benchmark Drops to 7.4 TFlops

coolmacdude writes "Well it seems that the early estimates were a bit overzealous. According to preliminary test results (in postscript format) on the full range of CPUs at Virginia Tech, the Rmax score on Linpack comes in at around 7.4 TFlops. This puts it at number four on the Top 500 List. It also represents an efficiency of about 44 percent, down from the previous result of 80 achieved on a subset of the computers. Perhaps in light of this, apparantly VT is now planning to devote an additional two months to improve the stability and efficiency of the system before any research can begin. While these numbers will no doubt come as a disappointment for Mac zealots who wanted to blow away all the Intel machines, it should still be noted that this is the best price/performance ratio ever achieved on a supercomputer. In addition, the project was successful at meeting VT's goal of developing an inexpensive top 5 machine. The results have also been posted at Ars Technica's openforum."

snazzy new G5 logo too!

Way to go /. -- updated the logo from G4 to G5 just in time.

the REAL reason to build a top-5 supercomputer

[Anonymous Coward]

What they're not telling you is that the real reason they are building a supercomputer is because the only copy of the router passwords is GPG-encrypted, and they lost the key.

Big mac cluster..

[jandrese]

That's nothing, last time I benchmarked my Big Mac Cluster (100 Big Macs) it came to almost 57.6 megacalories. Those Apples will never be able to match that!

1 Cal (uppercase C) is the amount of heat required to raise the temperature of 1g of water 1 degree celsius

which brings up a totally off topic question.... a can of coke is 350 ml. it contains 300 calories.

now, let's say i drink this coke. it is really cold - say 4 degrees. my body temperature is a nice, mamallish 37 degrees. by drinking this coke i am warming up 350 g of what is essentially water from the temperature of the can to that of my body - a difference of 33 degress.

33c * 350ml = 11550 calories.

since the coke is only 300ish calories in the first place...

why don't i lose weight drinking ice cold coke?

I find your ideas intriguing and would like to subscribe to your newsletter.

Does anyone else have trouble reconciling...

"best price performance" and "Apple" in their minds?

Catch Phrase

[humpTdance]

Best Price/Performance ratio = promotional video with the phrase:

"Virginia Tech: Home of the Poor Man's Supercomputer and Michael Vick."

Big Mac? How does that compare with a WOPR?

Re:A supercomputer by Any Other Name....

[BostonPilot]

Nah, the real defintions is:

Super computers cost more than 5 million dollars

Mainframes cost more than 1 million dollars

Mini-Super computers cost more than 1/4 million dollars

Everything else is by definition a Plain Jane (TM) computer

btw, I've worked on all 4 kinds ;-)

Thats nothing

[madpierre]

I installed a button on the front of my cluster
to manually clock the CPU's.

So far i've managed ONE whole flop.

My record is for the slowest supercomputer
on the planet.

Build a computer that uses all CMOS static registers.

Attach a hall-effect sensor to a hamster wheel to drive the clock.

Go out and buy a hamster.
