Supercomputing made simple

New software helps tap unlimited power of idle PCs


(Popular Science) -- Millions of science enthusiasts currently loan their unused PC power via the Web to researchers who need it in the hunt for medical cures and scientific eurekas.

Millions more will likely follow suit later this summer when Berkeley scientist David Anderson debuts an easier and cheaper way to write distributed computing software. (Volunteers simply download a screensaver and the software does the rest.)

Anderson, creator of the world's first and most popular distributed computing program, SETI@home, inspired 4 million folks to help his team analyze radio signals for signs of extraterrestrial intelligence.

About a dozen other research projects now rely on distributed computing programs for supercomputing power, but until now, the software has been expensive and time-consuming to create.

Anderson's free open-source software should change that.

"The more projects that start using distributed computing the more people will be interested in lending their computers for research," says Anderson. In the meantime, here are four ways to put your idle PC to good use.

Screensaver mission

Screensaver missionThe Great Internet Mersenne Prime Search (GIMPS) Searches for ever-larger, world-record-setting Mersenne prime numbers.

PC's in use: 130,000

Avg. power on tap*: 9 teraflops

The payoff so far: GIMPS has discovered five Mersenne primes in six years, including one with more than 4 million digits. A PC would need 25,000 years to do that!

Screensaver mission

SETI@home Searches for signals from extraterrestrial civilizations. Suspicious units are flagged and scrutinized.

PC's in use: 4,350,000

Avg. power on tap*: 56.2 teraflops

The payoff so far: Idle computers have analyzed more than 5 billion possible ET signals. So far, 166 have warranted a closer look, though none have panned out.

Screensaver mission

The Smallpox Research Grid Searches for drugs that fight the smallpox virus. Each PC analyzes sets of 110 potential drug candidates.

PC's in use: 2,000,000

Avg. power on tap*: 180 teraflops

The payoff so far: Since February the grid has screened 35 million potential drug candidates, a chore that would take a single CPU 7,000 years to complete.

Screensaver mission

Climateprediction.net Set to launch this summer, the screensaver will help predict significant changes in Earth's climate.

PC's in use: Launching 2003: Hopes to lure one million users

Avg. power on tap*: Unknown

The payoff so far: The project recruited 15,000 users in the two-week testing phase. Download the real thing this summer. * A teraflop equals a trillion calculations per second. The world's largest supercomputer operates at 35.9 teraflops. The average PC manages approximately 0.0001 teraflops.

On the run for D.B.!

kloppen die waardes wel voor Seti en UD Grid?
seti: 4.350.000 pc's en 56.2 teraflops
ud: 2.000.000 pc's en 180 teraflops

Verwijderd

Dan zouden die UD computers gemiddeld een stuk moderner zijn... lijkt me niet waarschijnlijk bij dergelijk grote aantallen.

Koffie? Hmmm, ja, lekkerrr

Het kan natuurlijk ook zijn dat het ene DC project efficienter met de CPU resources omgaat als een ander. Seti staat er bijvoorbeeld om bekend dat het nogal gevoelig is voor de bandbreedte van de FSB...

seti loopt ook al erg lang en als je dan alle pc's die het ooit gedraait hebben opteld kun je er best op uit komen. ik heb het zelfs nog op 486 zien draaien in the good old days. Die dingen doen toch een flopje of wat minder dan de huidige kanonnen.

BTW dat laatste project lijkt me buitengewoon iteressant. Zo kunnen we zien wanneer we van koeien in zeekoeien veranderen :P
