CHINA’S LATEST SUPERCOMPUTER VICTORY

China’s Milky Way 2 supercomputer was recently declared the fastest supercomputer in the world by industry scorekeeper Top500, the latest move in the increasingly international race for high performance computing supremacy. Late last month, CI Senior Fellow Rick Stevens appeared on Science Friday, alongside Top 500 editor Horst Simon, to talk about why that competition matters, and what the global push for faster computation will do for medicine, engineering and other sciences.

“These top supercomputers are like time machines,” Stevens said. “They give us access to a capability that won’t be broadly available for five to ten years. So whoever has the time machine is able to do experiments, able to see into the future deeper and more clearly than those that don’t have such machines.”

The same time machine metaphor was also picked up by the University of Chicago’s profile of Mira, our local Top500 competitor, which was bumped down to #5 by the Milky Way 2’s top ranking. But there’s no shame in fifth-best, when fifth-best can run 10 quadrillion calculations per second — the equivalent computing power of 58 million iPads. CI Senior Fellow Gregory Voth is quoted about how access to such a world-class resource helps both today and tomorrow’s scientists.

“Having access to a computing resource like Mira provides excellent opportunities and experience for educating up-and-coming young scientists as it forces them to think about how to properly utilize such a grand resource very early in their careers,” Voth says. “This gives them a unique perspective on how to solve challenging scientific problems and puts them in an excellent position to utilize computing hardware being imagined now for tomorrow.”

WHY DATA SCIENCE MUST BE OPEN SCIENCE AND MORE FROM DSSG

The Data Science for Social Good fellowship has reached the halfway point, and the website is starting to fill up with interesting content about the projects. Some fellows have already produced tools for the community to use, such as Paul Meinshausen’s interactive tree map of the City of Chicago’s Data Portal. Instead of a cold, no-frills list of the datasets available for download by the public, Meinshausen’ s map uses color and shape to guide users quickly to the data they are seeking and make rapid comparisons about the size of the dataset. The visualization was popular enough that programmers in Boston and San Francisco quickly applied his code to their own city’s data portals, while another built a common map for every city that uses Socrata software to share its data.

Brett-Harris-WebFROM CITY HALL TO HYDE PARK

In its early days, the Urban Center for Computation and Data formed a valuable partnership with the data team installed by Mayor Rahm Emanuel within Chicago’s city government. Leading the city’s efforts to free up data internally and externally was Chief Data and Information Officer Brett Goldstein, an alumnus of the UChicago computer science program and the restaurant reservation startup company OpenTable. Goldstein’s team and UrbanCCD worked together on the SmartData platform proposal that was chosen for a $1 million grant in the Bloomberg Mayors Challenge earlier this year, and Goldstein was the keynote speaker at the first workshop of the Urban Sciences Research Coordination Workshop in February.

So we are very excited about the news that Goldstein will soon be joining the University of Chicago as the inaugural Fellow in Urban Science at the Harris School of Public Policy. Goldstein will continue to work with UrbanCCD researchers on the SmartData platform and other projects, while also helping with the launch of a masters degree in computation and public policy and the Urban Technology Innovators’ Conference, a new initiative organized by Chicago Harris and the City of Chicago that seeks to create a peer-learning network for municipal technology innovators.

“Chicago Harris demonstrates a commitment to rigorous interdisciplinary scholarship, with strong partnerships with the Department of Computer Science and the Computation Institute, and a desire to advance the field of data science, especially so it can be leveraged it for public service,” Goldstein said. “I am excited about the opportunity to continue working to meld urban science and data analytics and work with this impressive community of faculty and staff.”

WE CAME, WE SAW, WE CERNED

We were thrilled to spend Friday morning with the folks at TEDxCERN via webcast, enjoying fascinating talks by CI director Ian Foster and several other amazing scientists and educators. Foster’s talk focused on “The Discovery Cloud,” the idea that many complex and time-consuming research tasks can be moved to cloud-based tools, freeing up scientists to accelerate the pace of discovery. We’ll post the video when it’s up, but for now, enjoy this great animation produced for the conference by TED-Ed explaining grid computing, cloud computing and big data.

OTHER NEWS IN COMPUTATIONAL SCIENCE

Speaking of CERN, ISGTW ran a lengthy profile of the computing grid that powers the particle physics research on their Large Hadron Collider. In the three years since the LHC started running, it has produced 70 petabytes of data, which is subsequently distributed around the world to over 150 sites for coordinated and parallel analysis. As Wired wrote back in 2004, the LHC grid was built on Globus Toolkit, created by Ian Foster and Carl Kesselman, “the Lewis and Clark of grid computing.”

Some of the science-as-a-service ideas Foster discussed in his TEDxCERN talk were brought up a week earlier by Renee DiResta in O’Reilly Radar. Companies that provide 3D microscopic scanning, data platforms for computational biology or drug discovery and even connections with freelance scientists are featured.

Computation is eating science, and that’s a good thing…but funding agencies and researchers need to change or be digested, writes Will Schroeder at Kitware.

TEDxCERN_headerWHEN TED MEETS CERN

We’re happy to announce that Computation Institute director Ian Foster will be speaking at the first-ever TEDxCERN conference, to be held May 3rd at the particle physics laboratory in Geneva, Switzerland. The theme of the conference is “Multiplying Dimensions,” and Foster will speak in the second session on the topic of “Big Process for Big Data.” Other speakers include geneticist George Church, chemist Lee Cronin and philosopher John Searle. A webcast of the conference (hosted by Nobel Laureate George Smoot) will run on the TEDxCERN website, but the CI will also host a viewing party at the University of Chicago. Stay tuned for details, and enjoy the TEDxCERN animation on the origin of the universe — one of five animations (including one on big data) that will premiere at the event.

THE ILLINOIS SUPERCOMPUTER NEIGHBORHOOD GROWS

On Thursday, the National Center for Supercomputing Applications at the University of Illinois celebrated the full launch of Blue Waters, their new one-petaflop supercomputer. As part of the ceremony, Governor Pat Quinn declared “Blue Waters Supercomputer Day,” and Senator Dick Durbin saluted the machine and other supercomputers as “the gateway to next-generation research.” The start of 24/7 research was also a proud day for Computation Institute scientists such as Michael Wilde and Daniel Katz, who were involved in getting Blue Waters up and running. Wilde spoke about the supercomputer at the CI’s Petascale Day event last October.

Meanwhile, a couple hundred miles north of Blue Waters, Argonne’s new 10-petaflop supercomputer Mira nears the start of its own full production period later this year. This week, the laboratory released a new timelapse video of the machine’s construction, which you can watch below. But science isn’t waiting for Mira to reach full strength, as demonstrated by this new project on the combustion and detonation of hydrogen-oxygen mixtures — a potential alternative source of fuel.

THE GRAND MOTHER OF CLOUD

In recent years, cloud computing has crossed over from inside baseball IT chatter to the general public. As CI fellow Rob Gardner recently charted, web searches for the term began climbing in 2009 and still vastly out-pace searches for similar buzzwordy topics such as “big data” and “virtualization.” Now that consumers are comfortable with storing files and running programs in the cloud, it’s time for the pioneers of that technology to take their victory laps. One recent round-up of cloud computing mavericks at Forbes tagged CI fellow Kate Keahey as “the grand mother of cloud,” recognizing her early work on infrastructure-as-a-service (Iaas) platforms. Her current project, Nimbus, is dedicated to providing cloud-based infrastructure for scientific laboratories.

OTHER NEWS IN COMPUTATIONAL SCIENCE

A lot of what we know about science may be wrong, but finding those flaws could lead to better discovery in the future. That’s how this article on Txchnologist framed the new Metaknowledge Network led by CI fellow James Evans. “We’re building on decades of this deep work on science and trying to connect it to this computational moment…to get a quantitative understanding of why we have the knowledge we have,” Evans told reporter Rebecca Ruiz.

The open release of data by the city of Chicago hasn’t just improved our understanding of how the city works, but also how we see it. These beautiful visualizations created with the Edifice software (one of the projects at the Open City collaborative) make the neighborhoods of Chicago look like a genomic SNP chip…or an elaborate Lite Brite project.

Many Chicago homes would benefit from improvements that improve energy efficiency, saving them a huge portion of their monthly utility bills. But many residents are unaware of the option or unwilling to bear the up-front expenses needed to retrofit homes to reduce energy usage. According to WBEZ, two University of Chicago students have founded a new startup called Effortless Energy that uses data-mining techniques to both locate and assist these opportunities for conservation and savings.

The “traveling salesman problem” of finding the most efficient route between 20 different cities has long frustrated mathematicians. So English scientists created “programmable goo” to find the shortest route in similar fashion to studies that have used slime mold as navigators. You can read the paper, “Computation of the Traveling Salesman Problem by a Shrinking Blob” at arXiv.

topfinalists_inpage_newWin0312SMARTDATA PLATFORM GETS BLOOMBERG NOD

A few weeks ago, we urged readers to vote in the Bloomberg Mayors Challenge for the City of Chicago’s entry, a collaboration with the Urban Center for Computation and Data called the SmartData Platform. This week, the project received good news as it was chosen for a $1 million grant from Bloomberg Philanthropies to launch the project, one of five proposals to receive funding from the original pool of 305 applications. The SmartData platform will put city datasets — like those that can found on the city’s data portal — to work in making the city run more effectively and efficiently, and the UrbanCCD will help provide the computational expertise and tools to extract the maximum potential from the data. The new open-source platform is considered the next iteration of the WindyGrid system currently used internally by the city, which was discussed by Chicago’s Chief Data Officer Brett Goldstein at the recent Urban Sciences Research Coordination Network workshop.

Chicago and the other Bloomberg winners were covered by the New York Times, the Chicago Sun-Times, Crain’s Chicago Business, NBC Chicago, ABC Chicago, The Atlantic Cities,

THE PRESIDENT COMES TO ARGONNE

The security at Argonne National Laboratory will be even tighter than usual today as President Barack Obama visits to deliver a speech on the subjects of energy and climate change. The Presidential visit comes just months after the announcement of the Argonne “Battery Hub,” a $155 million project that’s part of the national Joint Center for Energy Storage Research. But President Obama’s speech will also come at a time where national laboratories such as Argonne face budget cuts due to the federal sequestration.  If you want to see what the President says about these pressing topics, tune into White House Live at 1:30 p.m. Central time.

OTHER NEWS IN COMPUTATIONAL SCIENCE

Next month will feature a lot of exciting CI-affiliated events. On April 3rd, Senior Fellow Gregory Voth will deliver a lunchtime talk in downtown Chicago on “Molecular Modeling: A Window to the Biochemical World” (register here). The 2013 edition of the GlobusWorld meeting runs from April 16-18 at Argonne, and registration for the conference and hotel rooms is currently open. Finally, the Computation Institute will host the inaugural Day of the Beagle symposium on April 23rd, celebrating the groundbreaking biology and medicine research performed on the Beagle supercomputer in its first year of operation.

The first supercomputer in the country of Jordan was built with somewhat unusual components: the processors from Playstation 3 video game consoles. As the article discusses, it follows a US Air Force supercomputer in using video game parts for high-performance computing.

Two visions of the future of computing received attention in recent weeks. A special issue of Science put the spotlight on quantum computing and recent experiments that move it closer to real-world application, and a feature on the new Nova Next website speculated on how synthetic biology could someday create computers made up of biological components.

“The Internet of Things” is catching on as a tech/computing buzzword, and in this video for the business news site Quartz, Robert Mawrey of ioBridge uses a fresh cup of coffee to explain why might soon want our appliances to send and receive tweets.

r-BLOOMBERG4-large570A CITY PROJECT BATTLE ROYALE

As the keynote speaker at the Urban Sciences Research Coordination Network kickoff last Friday, the City of Chicago’s Brett Goldstein presented a blizzard of exciting city projects at various states of development. One slightly-under-wraps project Goldstein touched upon was the SmartData platform, an ambitious plan to craft a new tool for decision-making and city services out of the abundant raw material of city data. In collaboration with the Computation Institute and the Urban Center for Computation and Data, the city’s Innovation and Technology team hopes to create a tool that will analyze the city’s many large datasets in real time to help the city respond to challenges more quickly and efficiently, while providing frequently updated, useful information to its citizens.

Wednesday, that exciting new effort was announced as a finalist in the Bloomberg Philanthropies Mayors Challenge, a competition among ideas proposed by cities across the United States. As part of the judging, the public is invited to vote for their favorite project among the 20 finalists at the Huffington Post. We’re biased of course, but to help make the case for Chicago’s project, you can read more about the SmartData platform here, or watch a video about the concept featuring Mayor Rahm Emanuel below.
