New York: Engineers, one of them of Indian-origin, have successfully developed a single-chip microprocessor that uses light for communications  – a landmark development that opens the door to ultrafast, low-power data crunching.

The researchers packed two processor cores with more than 70 million transistors and 850 photonic components onto a 3-by-6-millimetre chip.

They fabricated the microprocessor in a foundry that mass-produces vbhigh-performance computer chips, proving that their design can be easily and quickly scaled up for commercial production.

The new chip marks the next step in the evolution of fiber optic communication technology by integrating into a microprocessor the photonic interconnects, or inputs and outputs (I/O), needed to talk to other chips.

“This is a milestone. It’s the first processor that can use light to communicate with the external world,” said Vladimir Stojanovic, associate professor of electrical engineering and computer sciences at the University of California-Berkeley.

No other processor has the photonic I/O in the chip.

Stojanovic and fellow UC Berkeley professor Krste Asanovic teamed up with Rajeev Ram at the Massachusetts Institute of Technology and Milos Popovi at the University of Colorado, Boulder, to develop the new microprocessor.

“This is the first time we’ve put a system together at such scale, and have it actually do something useful, like run a programme,” added Asanovic.

The team found the chip had a bandwidth density of 300 gigabits per second per square millimeter, about 10 to 50 times greater than packaged electrical-only microprocessors currently on the market.

The photonic I/O on the chip is also energy-efficient.

The achievement opens the door to a new era of bandwidth-hungry applications.

One near-term application for this technology is to make data centres greener.

According to the US Natural Resources Defense Council, data centres consumed about 91 billion kilowatt-hours of electricity in 2013 – about two percent of the total electricity consumed in the US.

The paper was published in the journal Nature. (IANS), (image courtesy:kenstonlocal.org)

  • JY Pillay has been appointed as the acting President of Singapore
  • Pillay, also the Chairman of the Council of Presidential Advisers, is a veteran civil servant of Indian Origin
  • The Singapore polls take place on 23rd September

September 2, 2017: Indian-origin veteran civil servant JY Pillay on Friday took over as Singapore’s acting President until a new head of the state is elected later this month.

The temporary appointment of Pillay, Chairman of the Council of Presidential Advisers (CPA), follows the completion of President Tony Tan Keng Yam’s six-year term on Thursday, the Strait Times reported.

The nomination day for the Presidential election is September 13, followed by polling day on September 23.

According to the report, when the office of President is vacant, the first in line to exercise its powers is the CPA Chairman, followed by the Speaker of Parliament. This is the first time the office has fallen vacant since the elected presidency was introduced in 1991.

Pillay is no stranger to exercising the powers of the President. As CPA Chairman since 2005, he has been acting President each time the President goes on an overseas trip. He acted as President in May, when Tan made state visits to Europe.

He has served more than 60 such “stints”– the longest of which was 16 days in April and May of 2007 when then President SR Nathan visited Africa. (IANS)

  • He refused to defend US President Donald Trump’s economic agenda following the racial violence in Virginia
  • He said he will speak out against such abuse as long as he has a platform to do so

Washington, August 24, 2017: An Indian origin CEO says he was racially abused and was told to “go back” to India and also take along top Indian-American diplomat Nikki Haley after he refused to defend US President Donald Trump’s economic agenda following the racial violence in Virginia.

Ravin Gandhi, founder, and CEO of GMM Nonstick Coatings, a global supplier of coatings for cookware and bakeware, penned an op-ed for CNBC following the Charlottesville racial violence but in response was slammed and racially abused by readers, the Chicago Tribune reported.

 At least one woman was killed and dozens were injured in Charlottesville last week during clashes between white supremacists and counter-protestors at a rally. Trump, instead of blaming white supremacists, held both sides responsible for the violence and was criticised by both Democrats and Republicans for the response.

“I recently told the New York Times I was ‘rooting’ for certain aspects of Trump’s economic agenda,” Gandhi, 44, wrote in the article.

“After Charlottesville and its aftermath, I will not defend Trump even if the Dow hits 50,000, unemployment goes to 1 per cent, and GDP grows by 7 per cent… I will not in good conscience support a President who seems to hate Americans who don’t look like him.

“The fact that Trump equated hate groups with those protesting hate lit me up,” Gandhi said. “His moral leadership on this issue is reprehensible.”

US-born Gandhi, after his op-ed was published, received a voicemail from an alleged Trump supporter, who told him to “get your (expletive) garbage and go back to India”.

“You can take that other half-(expletive) Bangladesh creep with you, Nikki Haley,” the woman said in the message.

“She’s the one that started all this when she took down the Confederate flag. So don’t tell us that you gave him a chance. We don’t give an (expletive) who you gave a chance, OK? We’re going to start taking down Buddhist statues and see how you and Nikki Haley like that.”

The caller told Gandhi to “go clean up your own (expletive) country, it’s a filthy mess”.

He soon posted the voicemail on the social media and also shared the nastier emails he received, the report said.

“It was obvious that people thought my professional position somewhat protected me,” he said. “I wanted to show people that racism is blind to socioeconomics.

“Even though my race is a complete non-issue in my day-to-day life, the sad reality is there’s a group of racists in the USA that views me as a second-class citizen,” he said.

“I wanted my peers in the business community, the civic community, my friend community to see that this can happen to me. Because there’s this delusion that racism is dead because (Barack) Obama was elected (President),” Gandhi said.

He said while his sharing a “bigoted” voicemail may not make a big difference, he will speak out against such abuse as long as he has a platform to do so. (IANS)

  • The new research uses an algorithm that analyzes writing styles to identify authors and could be applied to online trafficking ads
  • A second algorithm can use time stamps to trace ad payments to accounts known as wallets at Bitcoin

A U.S. researcher Rebecca Portnoff says that she has developed automated ways to identify links between online sex trafficking ads and the digital currency Bitcoin, techniques that may help locate children being sold for sex.

Law enforcement and anti-trafficking groups could use the methods to investigate Backpage.com, an online classified advertising site where sex ads can be found, according to a statement by the University of California Berkeley, where the research was based.

About 1.5 million people in the United States are victims of human trafficking, mostly for sexual exploitation, according to anti-trafficking groups.

Most sex trafficking victims are children, and most are advertised or sold online, according to a U.S. Senate subcommittee report released this year.

Algorithms do the digging

The new research uses an algorithm that analyzes writing styles to identify authors and could be applied to online trafficking ads, Rebecca Portnoff, its lead author, said Thursday.

A second algorithm can use time stamps to trace ad payments to accounts, known as wallets, at Bitcoin, a web-based digital currency that allows money to move quickly and anonymously.

Comparing time stamps of ad purchases on Bitcoin and time stamps and information on Backpage ads could help identify who is paying for them, said Rebecca Portnoff, a UC Berkeley doctoral candidate in computer science who developed the techniques as part of her dissertation.

“Where previously you might have five different phone numbers that you had no idea were connected when you can see that they all came from the same wallets, that the same person paid for them, that’s a concrete sign that these five phone numbers are all related to each other,” Rebecca Portnoff said.

Rebecca Portnoff added, “I knew this was an issue that law enforcement was especially interested in.”

Boost for law enforcement

Having automated style and time stamp analyses to identify sex ads by authors and Bitcoin owners is significant, said Damon McCoy, a New York University Tandon School of Engineering assistant professor of computer science and engineering and a co-author of the research.

“Any technique that can surface commonalities between ads and potentially shed light on the owners is a big boost for those working to curb exploitation,” McCoy said in a statement.

The National Center for Missing and Exploited Children has said more than 70 percent of the reports it gets of trafficked children involve Backpage, based in Dallas, Texas.

Backpage did not respond to a request for comment.

The findings will be published by the Association for Computing Machinery’s Conference on Knowledge Discovery and Data Mining, UC Berkeley said.

It said the work was funded by the Amazon Web Services Cloud Credits for Research Program, the technology, and security firm Giant Oak, Google, the National Science Foundation and the U.S. Department of Education. (VOA)
