Astrophysicist Replaces Supercomputer with 8 PS3


Recommended Posts



"Suffering from its exorbitant price point and a dearth of titles, Sony's PlayStation 3 isn't exactly the most popular gaming platform on the block. But while the console flounders in the commercial space, the PS3 may be finding a new calling in the realm of science and research.


Right now, a cluster of eight interlinked PS3s is busy solving a celestial mystery involving gravitational waves and what happens when a super-massive black hole, about a million times the mass of our own sun, swallows up a star.


As the architect of this research, Dr. Gaurav Khanna is employing his so-called "gravity grid" of PS3s to help measure these theoretical gravity waves -- ripples in space-time that travel at the speed of light -- that Einstein's Theory of Relativity predicted would emerge when such an event takes place.

Good find on Dr. Khanna.


Check out his other papers on ArXiv.org.


Here's a good one regarding the slow limit collission of two spinning black holes. It was published during the middle of Titor's explanation of how his gadget worked (January, 2001):




The conclusions don't bode well for Titor's Gadget because his paper comtemplates events similar to Titor's two spinning holes that are in close proximity. In addition to Hawking Radiation, about 1% of the mass of the holes is released as gravitational wave energy as the event horizons intersect.


Remember that 1 gram of mass is equivalent to ~22 kt TNT, which happens to be the approximate yield of the Hiroshima device.


Based on Ttor's statement that his gadget (the box, components and tow black holes) weighed in at 500 lbs (~225 kg) we estimate that his black holes had a mass on the order of 100 kg each. If the two holes collided as Titor described them (their horizons intervwined as it were) the yield would be on the order of 2 kg, 2000 times greater than a simple Hiroshima device. That's a 44 megaton maximum yield without regards to any Hawking Radiation. It also doesn't bode well for his Wiggle VGL gadget. Two kilograms of gravitational energy released locally might "confuse" his gravity lock somewhat.

Pretty impressive they can use stock PS3's without having to perform some kind of illegal hack like "other" devices. PS3's are the first consumer tflop pc's I think so that makes them pretty historic IMO. go open source! Two of his rigs could probably take a spot on the top 500 list of fastest supercomputers.
