Students prepare for Sc10 competition

October 21, 2010—Next month a real-time, 46-hour non-stop competition will consume students from around the world.

The event, the 2010 Student Cluster Competition, is set to take place during an international conference on high performance computing, networking, storage and analysis, to be held Nov. 13-19 in New Orleans, Louisiana.

SC10

The competition will feature eight teams of undergraduate students building, tuning and racing high-performance computing (HPC) clusters of their own design on the conference's showfloor. The teams will race against each other and the clock to run the greatest number of applications. An added catch is that teams will be required to run workloads on the same power needed to run only three coffeemakers. Now in its fourth year, the Student Cluster Competition serves to showcase young computing talent and foster HPC education development.

“By showcasing some of the best young talent in HPC at SC10, the cluster challenge is a win for students, the institutions they represent, sponsors and cluster computing itself,” said Tiki Suarez?Brown, co?chair of this year’s competition, “The competition also demonstrates that cluster computing is making HPC more accessible to smaller companies, businesses and educational institutions.”

In the lead-up to the big day, the competing teams are currently perfecting designs and preparing to build cutting?edge clusters from commercially-available components. After the starting gun at SC10, teams will compete to achieve the best HPC benchmark performance and maximum throughput of accurate applications runs, all while remaining at or below their 26 amp energy budget.

Participating students range from National Tsing Hua University (Hsinchu, Taiwan), Nizhni Novgorod State University (Nizhni Novgorod, Russia), Florida A&M University, University of Colorado, Purdue University, and more.

Last year, a team from Stony Brook University, New York, won the SC09 Student Cluster Competition, sponsored by AMD, Dell and Mellanox Technologies.

The Student Cluster Competition (SCC) is organized collaboratively by the SC10 Technical and Communities Programs to foster HPC education development by providing an intense hands-on experience to high school and undergraduate students throughout the year. The SCC is only partially funded by the SC conference. 

Also of interest to students, SC10 will host a student job fair.

SC10 will be held in the Ernest N. Morial Convention Center, New Orleans, Louisiana, November 13?19, 2010. For more information, see http://sc10.supercomputing.org/.

NSF Calls for Proposals to Get More Women in Faculty Positions

August 11, 2010 —Barbara LiskovGot any ideas for how to get more women teaching science, technology, engineering, and math (STEM) at the collegiate level? The National Science Foundation is looking for some help.  

The NSF this week announced a call for proposals to attract and advance more female faculty members in the STEM fields. The program is called ADVANCE: Increasing the Participation and Advancement of Women in Academic Science and Engineering Careers. 

According to the NSF, the goal of the program "is to develop systemic approaches to increase the representation and advancement of women in academic STEM careers, thereby contributing to the development of a more diverse science and engineering workforce.  ADVANCE focuses on ensuring that women faculty with earned STEM degrees consider academia as a viable and attractive career option." However, the NSF is specifically not looking for ways to increase the number of female PhD candidates. Rather, the focus is on what comes after that phase. Additionally, proposals that address issues of attracting more women from underrepresented backgrounds  and increasing international collaboration will be favored.

The deadline to submit a letter of intent is October 4, 2010, and the deadline for full proposals is November 8, 2010. The program will continue in 2011 as well, with new submission dates of October 3, 2011, and November 7, 2011. 

To participate or learn more in about women in computing specifically, visit ACM-W, the Association for Computing Machinery's special group for celebrating, informing, and supporting women in computing. The image shown is Barbara Liskov, the 2008 ACM A.M. Turing Award winner, one of several women of distinction in computing highlighted on ACM's site. 


Human computation in Archaeology

July 11, 2010 — It's not uncommon to ask for public assistance in finding missing persons; however, it's not everyday that the public is asked to assist in finding an 800-year old missing tomb. The lost tomb of Genghis Khan is believed to be located in the Valley of the Khans, Mongolia, but the size of this sacred region, as well as local traditions prohibiting its disturbance, call for unconventional search methods.

Dr. Albert Lin of UC San Diego and his team apply non-invasive search methods to identify archaeological sites without disturbing them. Their approach includes detailed analysis of high-resolution satellite imagery, or in other words, combing through thousands of square miles of satellite images in search of clues to the tomb's location. This is clearly more than any single individual or team could ever handle. Surprisingly, it's also more than a computer can handle, as computers currently lack the visual perception required to find telltale anomalies in the photos.

That's where you, with your amazing human visual perception, can help out. National Geographic has recently released a Human Computation website, where volunteers can look through photos and tag suspicious locations. These tags will help guide the explorations of an expedition to Mongolia led by Dr. Lin over the month of July.

Programming 'Boot Camp' Offers Basic Training

By Marina Krakovsky (ACM News and CACM.acm.org)

June 15, 2010 — John Stamey 's breakthrough came during a moment of frustration. Several years ago, the Coastal Carolina University computer science professor was teaching second-semester students who, to his amazement, still couldn't so much as write a loop. So he ditched his syllabus and started from scratch. "I said, 'We're just going to do a boot camp. You have two weeks to write these 100 programs.'"

The drill-sergeant strategy worked: by term's end, Stamey says, "the level of programming went from nowhere to everywhere."

Since then he's taken the approach to the greenest recruits: CS majors taking his department's most elementary programming class, which uses Python to ease students into the key components of structured programming: statements in sequence, loops, and IF statements. Despite these modest learning goals, only 76 percent had typically finished with a C or better — but in the first boot camp, the pass rate jumped to 95 percent, with most students earning an A or B.

In contrast to the old curriculum, which assigned three to four programs per semester, the new course has each student write 370 very short programs. A typical program from midway through the boot camp prints the multiples of 10 from 200 to 400, one per line, or asks the user to input two numbers and print their sum and product. "It may get repetitive, but I'll tell you what: you'll learn," Stamey says.

The idea of teaching through hundreds of short programs isn't new. Northeastern University CS professor Matthias Felleisen , an ACM Fellow and winner of the 2009 Karl V. Karlstrom Outstanding Educator Award , has been doing it for about 18 years and popularized it in "The Little Schemer" (MIT Press, 1995). But the approach was a revelation for Stamey, who was excited enough by the results to present them at a conference and publish his own book, "Computer Science Boot Camp" (John W. Stamey, Jr., 2009).

Not everyone's impressed. Shriram Krishnamurthi , a computer scientist at Brown University who also teaches programming to middle-school and high-school students, questions the emphasis on particular programming constructs instead of more generalizable skills. "The student has not been given a way to do programming — they've learned the constructs of one programming language," he says. "What happens when the students go on from this to other courses?"

Some hit a wall. Stamey later found that although performance in the second-semester course did improve after students had taken the first-semester boot camp (compared to students who'd followed the old curriculum), the difference was less dramatic than in the first boot camp—a result Stamey attributes in part to the second-semester switch from C++ to C, which he says is a tougher language. But he remains confident the boot camp is good for his students, many of whom are drawn to Coastal Carolina for its low tuition and nearness to Myrtle Beach. "For students who don't have the best math skills when they come in, I think for some of them it helps." 

Mathematicians Solve 140-Year-Old Boltzmann Equation

University of Pennsylvania

May 18, 2010—Two University of Pennsylvania mathematicians have found solutions to a 140-year-old, 7-dimensional equation that were not known to exist for more than a century despite its widespread use in modeling the behavior of gases.The study, part historical journey but mostly mathematical proof, was conducted by Philip T. Gressman and Robert M. Strain of Penn's Department of Mathematics, Philadelphia, PA.

The solution of the Boltzmann equation problem was published in the Proceedings of the National Academy of Sciences. Solutions of this equation, beyond current computational capabilities, describe the location of gas molecules probabilistically and predict the likelihood that a molecule will reside at any particular location and have a particular momentum at any given time in the future.

During the late 1860s and 1870s, physicists James Clerk Maxwell and Ludwig Boltzmann developed this equation to predict how gaseous material distributes itself in space and how it responds to changes in things like temperature, pressure or velocity. The equation maintains a significant place in history because it modeled gaseous behavior well, and the predictions it led to were backed up by experimentation.

Despite its notable leap of faith—the assumption that gases are made of molecules, a theory yet to achieve public acceptance at the time—it was fully adopted. It provided important predictions, the most fundamental and intuitively natural of which was that gases naturally settle to an equilibrium state when they are not subject to any sort of external influence. One of the most important physical insights of the equation is that even when a gas appears to be macroscopically at rest, there is a frenzy of molecular activity in the form of collisions. While these collisions cannot be observed, they account for gas temperature.

The study was funded by the U.S. National Science Foundation.
