Scientists Build A Supercomputer From PlayStations To Study Black Holes
Scientists Build A Supercomputer From PlayStations To Study Black Holes
Government funding for research is becoming increasingly difficult to come by due to ongoing global economic instability, which is why many scientists are forced to look elsewhere to keep their research projects alive. Some are turning to crowdfunding, which is now allowing the UK to explore the moon, whereas others are practicing being thrifty. Dr. Gaurav Khanna is a perfect example of the latter, as he has managed to make an extremely cheap supercomputer using PlayStation 3 (PS3) games consoles. And he has even successfully used his ingenious invention to publish several scientific papers.
Khanna, a black hole physicist at the University of Massachusetts Dartmouth, began his budget supercomputer endeavor back in 2007. His research focuses on gravitational waves, which are ripples in the fabric of space-time produced by moving masses like stars or black holes, usually when two or more compact masses interact in a violent manner, such as colliding together.
Gravitational waves decrease in strength as they move away from the source, meaning that by the time they reach Earth they are extremely weak, which is why scientists have struggled to detect them. But rather than developing instruments to pick up these waves, Khanna uses supercomputers to simulate black hole collisions.
Supercomputers are useful tools because they can crunch massive numbers and solve calculations that are too big for a single processor. As Khanna explains to New York Times, supercomputers perform at least 10 times better than single desktop computers, but they are extremely expensive to build. Normally, supercomputers are constructed by linking together a large number of processors, such as standard computers. However, Khanna decided to use PS3s rather than desktops to build his model, partly because of their low cost (around $250), and partly because users can install their preferred operating system.
Khanna contacted Sony for help with his endeavour, who gladly donated four consoles. His university funded another 8, and he bought the remaining four he needed with his own money. He then installed Linux on all of them, hooked them up and connected them to the Internet. And voila- a budget supercomputer was born.
Two years on, he was able to show in a published paper that his invention could speed up calculations by a factor of almost 10 compared to a traditional desktop computer. That same year, he published a paper detailing the behavior of gravitational waves arising from rotating black holes, which was made possible by his new toy.
Khanna was then approached by the Air Force Research Laboratory whose researchers 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 price tag; a fraction of the cost of a traditional supercomputer. And it’s already helped Khanna publish two more scientific papers on black hole collisions. But his supercomputing journey isn’t over yet, as he is due another 220 consoles this year.
Unfortunately, these PS3 supercomputers will always be limited in terms of memory, which is significantly smaller than traditionally built machines. That’s why Khanna is now looking at using PC graphics cards, which are much more powerful than PS3s but still an inexpensive option.

BREAKING: AT&T buys DirecTV for nearly $50 billion
BREAKING: AT&T buys DirecTV for nearly $50 billion
AT&T agreed Sunday to buy DirecTV for about $48.5 billion in yet another mammoth deal in the pay-TV space this year that would immediately boost the telecom giant's customer base at a time of confounding industry challenges.
The merger, which both boards approved Sunday, is the latest evidence of TV-industry consolidation, one born of telecommunications companies' desire to amass customers and control content and delivery. With streaming and wireless technology upending the industry, cable and satellite service providers are rushing to add product options while boosting revenue per customer to please shareholders.
In the deal, AT&T would pay DirecTV shareholders $95 per share. Including DirecTV's debt, the total transaction's value is about $67.1 billion.
"Customers will be able to get wireless, voice, data, TV and home security from the same company nationwide," says Roger Entner, an analyst at Recon Analytics. "It allows them to grow the share of consumers' spending on telecom."
DirecTV shareholders will get $28.50 per share in cash and $66.50 per share worth in AT&T stock. In the stock portion of the deal, they will receive 1.905 AT&T shares if AT&T stock price is below $34.90 at closing or 1.724 AT&T shares if its stock price is above $38.58. If AT&T's stock price at closing is between $34.90 and $38.58, DirecTV shareholders will receive between 1.724 and 1.905 shares of AT&T stock, equal to $66.50 in value.
In anticipation of the deal -- their talks were first leaked on April 30 -- DirecTV shares have risen 12%.
"This is a unique opportunity that will redefine the video entertainment industry and create a company able to offer new bundles and deliver content to consumers across multiple screens," said Randall Stephenson, AT&T's chairman and CEO, in a statement Sunday.
AT&T offers pay-TV service through its U-Verse brand, but its market reach is limited. The acquisition broadens AT&T's footprint nationally and creates a pay-TV giant that can offer video through both fiber-optics lines and satellites. It would also give AT&T more flexibility in bundling services by leveraging its wireless networks and satellite-delivered TV-Internet service.
If approved by regulators, DirecTV will operate as an AT&T subsidiary and continue to be based in its current headquarters in El Segundo, Calif.
ANALYSIS: Why AT&T wants to buy DirecTV
AT&T U-Verse's TV service has about 5.7 million customers in 22 states. DirecTV, with about 20 million customers nationwide, is the second-largest pay-TV provider -- behind Comcast -- and the largest satellite TV company in the U.S. DirecTV also has 18 million customers in Latin America and offers AT&T an immediate access to that fast-growing market.
Their negotiation follows a deal struck earlier this year by Comcast to buy Time Warner Cable for about $45 billion, a transaction that would merge the nation's two largest cable companies.
With consumer groups loudly opposing media industry consolidation, AT&T and DirecTV could face difficult regulatory roadblocks. Unlike Comcast's deal, AT&T's acquisition of DirecTV eliminates a competitor in AT&T U-Verse's markets.
"The industry needs more competition, not more mergers," said John Bergmayer, an attorney at consumer technology advocacy group Public Knowledge. "The burden is on AT&T and DirecTV to show otherwise."
AT&T makes "commitments"
Sensing heavy scrutiny from federal regulators for its merger approval, AT&T and DirecTV listed several "commitments" that will be carried out after the deal closes. They include:
*Broadband expansion. AT&T's broadband service will be expanded to 15 million residential and commercial buildings mostly in rural areas where it's not currently present, it says. It'll use a combination of technologies, including building out fiber optic lines directly to your house or using a direct radio link to deliver Internet in the "last mile," between your home and the local exchange. This project is scheduled to be completed within four years after the merger close.
*Speed guaranty. For three years after the deal closing, AT&T will guarantee broadband Internet speeds of at least 6 megabits per seconds, "where feasible," for customers who only want an Internet service.
*DirecTV continuance. For "at least three years" after closing, DirecTV's TV service will be available on a stand-alone basis at current prices that are the same for all customers.
*Net neutrality. The combined company would also abide by net neutrality rules established in 2010 -- that ISPs can't discriminate against various types of legal content -- but tossed out earlier this year. The Federal Communications Commission is currently in the process of recasting the rules.
Need to grow sales-per-customer
The deal boosts AT&T's customer total, but its desire to grow revenue per customer -- a key industry metric -- also may have pushed the company's management to move quickly.
By folding satellite-TV service into its broad telecom portfolio -- wireless, phone and fiber-optic broadband and TV -- AT&T will be in an ideal position to create varied bundled packages to sell more options at its 2,300 retail stores and thousands of dealers and agents. It can sell wireless contracts with land-line broadband Internet, and package them with TV programming and other ancillary services, such as home security.
For customers in its non-U-Verse markets, it can offer its existing services along with satellite TV. Eventually, the company may also introduce Internet packages delivered on its fastest wireless networks if it can work out lower pricing levels and address issues surrounding monthly cap limits.
Currently, AT&T customers who have U-verse triple-play service, which includes land-line phone, broadband Internet and cable TV, spend about $170 each month (not including wireless service). With its satellite TV revenue alone, DirecTV generated $102.18 per user in 2013, up 5.4% from 2012.
On the content front, a combined company would also have more bargaining leverage in talks with content providers for retransmission and licensing fees. "You hope you can squeeze out some, if not lower rates, some slower-growing rates," says SNL Kagan analyst Ian Olgeirson.
Another possible result: a stronger TV-everywhere package -- combining wireless, satellite and fiber-optic networks -- could emerge from the merger, a plus for DirecTV. Its satellite TV competitor Dish Network sits on a sizable amount of wireless spectrum that could be used for broadcast.
With AT&T's deal removing yet another competitor in the TV and Internet businesses, net neutrality proponents' howls of protest will continue for months. It's widely known that DirecTV's satellite-delivered Internet is slow compared to cable companies, but it still has millions of customers.
The increased concentration of power among the few who provide braodband Internet would give AT&T more leverage if -- as the FCC has preliminarily proposed -- ISPs are ultimately allowed to charge for "fast lanes" of the Internet for content providers that are willing to pay for them.
Though the size of the deal is comparable to the $45 billion Comcast-Time Warner Cable deal, the competitive issues surrounding the two mergers are different. Comcast has deal to buy another provider of pay-TV and Internet service in Time Warner Cable, but the transaction would not eliminate a competitor in their markets.
"This is not Comcast-Time Warner Cable round two," says Amanda Wait, an attorney at Hunton & Williams and a former antitrust attorney at the Federal Trade Commission.
