A New Era in HPC
HPCwire
A recent presentation at the 2014 Computational Science Graduate Fellowship HPC workshop by the Lawrence Livermore National Laboratory's Rob Neely suggested high-performance computing (HPC) is poised for significant advancement. He examined the history of HPC and also identified emerging trends. Neely cited such key HPC concepts as scalability, shared versus distributed memory, Amdahl's law, Dennard scaling, data locality, burst buffers and I/O, heterogeneous computing, and co-design. He noted three significant computing eras, including mainframes, vector era, and distributed memory era (MPP). Neely also pointed out an emergent computing era that has thus far been difficult to classify. He furthermore discussed such dominant programming models as MPI and OpenMP along with the newer PGAS and task-based approaches. "There is no one defining feature of this new era like there has been in the past," Neely said. To read further, please visit http://www.hpcwire.com/2014/09/17/new-era-hpc/.
USGS Software Visualizes Evacuation Scenarios
Government Computer News
The recent upsurge in natural disasters suggests it is more likely there will be a need to evacuate people in a disaster zone at some point in the future. Researchers working with the U.S. Geological Survey have been developing software to assist pedestrian evacuation from disaster zones. The Web-based Pedestrian Evacuation Analyst app has been installed in Esri's ArGIS desktop advanced version to help determine the exposure to risk by evacuees and visualize evacuation scenarios from sudden-onset hazards, such as tsunamis. "By automating and managing the modeling process, the software allows researchers to concentrate efforts on providing crucial and timely information on community vulnerability to sudden-onset hazards," say researchers Jeanne Jones, Peter Ng, and Nathan Wood. The software can calculate the travel time to safety from any location in a study area, determine the population in the evacuation zone, and automate the processing of evacuation procedures.

Upcoming Workshops, Conferences and Webinars
"The Changing Nature of Invention in Computer Science" (webinar)
September 30, 2014 – 12:00pm ET
Presented by the 2013 ACM Fellow Dennis Shasha:
What drives inventions in computing? Necessity seems to play only a minor role. Anger at the way things are is much more powerful, because it leads to easier ways to work (the invention of new computer languages). A general dissatisfaction with the practical or theoretical structure of the world can open up whole new approaches to problems (complexity theory and cryptography). Finally, a genuine collaboration between people and machines can lead to an entirely new kind of engineering for devices that will travel to far-off planets or to hostile environments. The talk will discuss the work of several inventors in computing and engineering, their inventions, and how they came up with them and how they plan to come up with more in the future. The ensuing discussion will address the fundamental nature of invention in a world partly populated by intelligent machines.

Research News From Around the World
TACC Takes a Deep Dive into Plasma
Studying the intricacies and mysteries of the sun is physicist Wendell Horton life's work. A widely known authority on plasma physics, his study of the high temperature gases on the sun, or plasma, consistently leads him around the world to work on a diverse range of projects that have great impact. Fusion energy is one such key scientific issue that Horton is investigating and one that has intrigued researchers for decades. "Fusion energy involves the same thermonuclear reactions that take place on the sun," Horton said. "Fusing two isotopes of hydrogen to create helium releases a tremendous amount of energy — 10 times greater than that of nuclear fission."

PSC Breaking Out of the Digital Graveyard
Blacklight Used to Extract Meaning from Cursive Script, Allowing Scanned Documents to be Searched
In 1973, a fire broke out at the St. Louis National Personnel Records Center, destroying 16 to 18 million military service records from 1912 to 1964. If these records had been digitized they’d have been safe, but not necessarily any more accessible. Scanned PDF images, the low-cost, high-speed method for digitizing images, can be duplicated and stored in many places. But you can’t find anything in them, except by a human being searching through the handwritten text by eye. And the 1940 U.S. Census, for example, consists of 3.6 million PDF images. Commercial services like Ancestry.com employ thousands of human workers who manually extract the meaning of a small, profitable subset of these images so they can be searched by computer, says Kenton McHenry of the National Center for Supercomputing Applications (NCSA), To read further, please visit http://psc.edu/index.php/88-biannual-report-and-science-book/biannual-report/937-breaking-out-of-the-digital-document-graveyard.

Researchers who invested in the Farber cluster were granted access on Tuesday, Sept. 16. “Farber has been configured to be very similar to the Mills cluster,” said Jeffrey Frey, IT Network and Systems Services. “Researchers with experience on Mills should find Farber to be a familiar environment.” To read further, please visit http://www.hpcwire.com/off-the-wire/university-delaware-deploys-second-hpc-cluster/.
The Past, Present and Future of Engineering Simulation
InsideHPC
In this special guest feature from Scientific Computing World, Bill Clark, executive vice president of CD-adapco, considers the successes of computer-aided engineering through the “three ages of CFD. Computational Fluid Dynamics (CFD) is about solving difficult engineering problems, using expensive software, enormous computing resources, and highly trained engineers. If the problems weren’t difficult, then it is doubtful that anyone would devote so much time and money to solving them. From the perspective of a modern engineer, it would be easy to assume that this desire to apply simulation technology to complex problems is a recent concern; that only today are we able to contemplate solving tough industrial problems, armed with a complex array of multi-physics simulation tools. This is a misconception. To read further, please visit http://insidehpc.com/2014/09/past-present-future-engineering-simulation/.
Mapping Big Data
SDSU News
Researchers at San Diego State University (SDSU) are applying geographic mapping principals to large sets of unstructured data in hopes of gaining insights into the relationships between them. The mapping techniques being developed at SDSU's Center for Information Convergence and Strategy (CICS) focus on large sets of data that are in mutually unintelligible formats. The data can include everything from journal articles to blog posts, and CICS' mapping is meant to make the parallels and connections between them readily and quickly apparent. An example is a map the researchers made by feeding about 2 million medical journal articles into their algorithm. To read further please visit http://go.sdsu.edu/sdsu_newscenter/news.aspx?s=75173.
Engineers Develop Algorithms That Allow You to Switch Out and Recharge Battery Modules in Electric Cars
UCSD News
University of California, San Diego (UCSD) researchers working on the Modular Battery Exchange and Active Management (M-BEAM) project are developing a method to swap out and recharge small units in electric car batteries, known as modules. "This idea may seem straightforward, but there were some tough technical challenges that we had to solve to make this system robust and practical," says Lou Shrinkle, one of the M-BEAM project's sponsors. The researchers say the technology can make energy storage more configurable, promote safety, simplify maintenance, and eventually eliminate the use of fossil fuels for these applications. An effective battery module-swapping technique also could be applied to mobile and decentralized electrical energy storage systems. The researchers will test the technology on a cross-country trip with a car powered by the removable, rechargeable M-BEAM battery modules.

New Global STEM Alliance Launched
FierceCIO
The New York Academy of Sciences has announced its new Global STEM Alliance, as well as releasing a new white paper outlining what it calls the global "STEM paradox." According to the academy, what is often thought of as a shortage of graduates in the science, technology, engineering, and mathematics (STEM) fields is actually a shortage of so-called "work-ready" graduates. This, along with a brain drain from developing nations and a lack of women in STEM fields, constitute the major STEM challenges around the globe. The academy plans to address these issues through its new STEM Alliance, which it will launch at the United Nations. The Alliance will have the goal of mentoring 1 million aspiring STEM leaders in over 100 countries by 2020.

Boosting Hispanic Share of Tech Workforce Could Be Key to Closing STEM Gap
NextGov.com
The Obama administration has set a goal of increasing student exposure to opportunities in the science, technology, engineering, and math (STEM) fields by 50 percent and the number of STEM college graduates by 1 million in the next decade. Cecilia Munoz, director of the White House's Domestic Policy Council, says encouraging greater Hispanic participation in STEM fields is a crucial part of that goal. Hispanics accounted for 15 percent of the U.S. labor force in 2011, but only 7 percent of the STEM workforce. In addition, 17 percent of the U.S. population is Hispanic, but only 10 percent of STEM bachelor degrees are earned by Hispanics. Munoz says the government sees this as "room for growth," and is trying to tap that potential with investments in higher-education programs that encourage Hispanics to pursue STEM careers. One such program is at the Georgia Institute of Technology, which boasts one of the highest rates of Hispanic STEM graduates in the country.

Failing Students Saved by Stress-Detecting App
New Scientist
Dartmouth College professor Andrew Campbell and colleagues recently conducted a 10-week experiment with 48 students to see if data gathered from their smartphones could be used to gauge their states of mind, and their likelihood to excel or struggle academically. The researchers developed the StudentLife app to track readings from smartphone sensors in such areas as physical activity levels, sleep patterns, frequency and duration of conversations, and global-positioning system location. Students who excelled interacted frequently with other people and have longer conversations, while depressed students were less social with others and exhibited excessive or disrupted sleep patterns.

STEM Springboard: New STEM Grads Get ahead
New college graduates with degrees in STEM fields have bucked a national trend. While too many of their peers graduate with heavy debt and scant job prospects, new graduates with degrees in STEM face a much brighter future. Not only are they more likely to land jobs, the jobs they land require higher skills, and they pay more. Change the Equation’s analysis of Census Bureau data reveals stark differences in jobless rates between STEM and non-STEM graduates Recent STEM graduates are also less likely to be under-employed. Those with bachelor’s degrees are much more likely to work in jobs that actually require a bachelor’s degree: To read further, please visit http://changetheequation.org/stem-springboard#overlay-context.
The Lighter Side
'Cloaking' Device Uses Ordinary Lenses to Hide Objects Across Range of Angles
Physics.org
Inspired perhaps by Harry Potter's invisibility cloak, scientists have recently developed several ways—some simple and some involving new technologies—to hide objects from view. The latest effort, developed at the University of Rochester, not only overcomes some of the limitations of previous devices, but it uses inexpensive, readily available materials in a novel configuration. There've been many high tech approaches to cloaking and the basic idea behind these is to take light and have it pass around something as if it isn't there, often using high-tech or exotic materials," said John Howell, a professor of physics at the University of Rochester. Forgoing the specialized components, Howell and graduate student Joseph Choi developed a combination of four standard lenses that keeps the object hidden as the viewer moves up to several degrees away from the optimal viewing position.

Teaching Computers the Nuances of Human Conversation
University of California Santa Cruz News
University of California, Santa Cruz professor Marilyn Walker says natural-language processing has become very good at recognizing human speech, but it still struggles to understand its subtle, yet crucial, nuances. In particular, it cannot yet pick up on the ways that word choice and sentence construction reveal a speaker's personality and the social relationships between people. Walker says developing software that can do that would be a major step along the road to creating companion robots and other naturalistic technology. One of the projects being worked on by Walker and her colleagues analyzes thousands of conversations from online debate forums.
