governing financing for research is becoming more and more hard to come by due to on-going global economic instability , which is why many scientists are force to look elsewhere to keep their enquiry projects active . Some are turning to crowdfunding , which is now allowing the UK to research the moon , whereas others are practicing being careful . Dr. Gaurav Khanna is a perfect lesson of the latter , as he has manage tomake an highly cheap supercomputerusing   PlayStation 3 ( PS3 ) games consoles . And he has even successfully used his ingenious invention to bring out several scientific theme .

Khanna , a ignominious hole physicist at the University of Massachusetts Dartmouth , began his budget supercomputer strive back in 2007 . His inquiry focuses ongravitational wave , which are ripples in the cloth of place - metre acquire by actuate masses like stars or contraband holes , usually when two or more compact stack interact in a wild manner , such as colliding together .

Gravitational wavesdecrease in strength as they move off from the source , meaning that by the time they get to Earth they are extremely weak , which is why scientist have struggled to detect them . But rather than developing instruments to pick up these waves , Khanna expend supercomputers to model black pickle hit .

supercomputer are useful pecker because they can crunch massive numbers and solve calculations that are too adult for a undivided processor . As Khanna explains toNew York Times , supercomputer do at least 10 time better than exclusive desktop computers , but they are extremely expensive to build . Normally , supercomputers are fabricate by linking together a large figure of processors , such as received computers . However , Khanna decide to use PS3s rather than desktops to build his manikin , partly because of their low cost ( around $ 250 ) , and partly because user can install their preferable operating system .

Khanna contacted Sony for help with his endeavor , who gladly donated four console . His university funded another 8 , and he bought the remaining four he needed with his own money . He then install Linux on all of them , cop them up and connected them to the Internet . And voila- a budget supercomputer was bear .

Two twelvemonth on , he was able to show in a write paper that his invention could speed up calculation by a agent of almost 10 compare to a traditional background computer . That same twelvemonth , he published a paper detail the demeanor of gravitative wave uprise from rotating black holes , which was made possible by his new plaything .

Khanna was then approached by the Air Force Research Laboratory whose investigator had already been looking into using PS3s to help them out with urban surveillance projects . The lab donated 176 consoles to Khanna , resulting in a supercomputer as powerful as 3,000 laptops . What ’s more , the remarkable machine came with a $ 75,000 terms shred ; a fraction of the price of a traditional supercomputer . And it ’s already help Khanna release two more scientific papers on bootleg jam collision . But his supercomputing journey is n’t over yet , as he is due another 220 consoles this year .

Unfortunately , these PS3 supercomputer will always be limited in term of memory board , which is significantly modest than traditionally built car . That ’s why Khanna is now face at using PC graphics cards , which are much more powerful than PS3s but still an inexpensive choice .
