This is the second installment of the SC15 Awards recap.  To read the first article, click here.

SC15 Posters Chair, Manish Parashar, addresses the SC15 attendees during the Best Poster and ACM Student Research Competition Awards presentation in Austin, Texas.

This article will recap the following from the SC15 Awards Ceremony:

• Best Posters
• The IEEE TCSC Award for Excellence in Scalable Computing for Early Career Researchers
• Scientific Visualization and Data Analytics Showcase
• George Michael Memorial HPC Fellowship
• ACM Student Research Competition
• ACM Gordon Bell Prize

SC Posters encourage collaboration and conversations.

The first awards segment to highlight is the robust posters competition, which includes the ACM Student Research Competition.  Research posters showcase some of the most cutting-edge research in high performance computing (HPC), storage, networking and data analytics.

Posters are always a great area for positive discourse.

This year, SC received 254 detailed submissions that went through a rigorous review process. In the end, 114 posters were accepted and seven finalists were selected for the Best Poster Award.

As part of its research poster activities, SC15 also hosted the ACM Student Research Competition. It enables undergraduate and graduate students to experience the research world, share results and exchange ideas. They also have a chance to rub shoulders with academic and industry leaders and gain an understanding of the applications of their research.

The Student Research Competition encourages research excellence.

This year, SC received 64 submissions that went through a rigorous review process. In the end, 25 Student Research Competition posters were accepted. The Student Research Competition includes travel support for all SC15 participating students as well as cash awards to the finalists. This award is co-sponsored by Microsoft Research.

The first place winners will move on to the Student Research Competition grand finals next year. According to SC15 Posters Chair, Manish Parashar, "The poster session is a very important activity where the poster authors and audiences enjoy face-to-face discussion on their technologies for a broader audience and great exposure for their work."

SC15 Awards Recap: Part 1

Once again, the SC Awards Ceremony was an entertaining event and one of the many highlights of conference week. This year, the SC15 Award Co-Chairs were Padma Raghavan and Franck Cappello who helped open the SC15 Awards Ceremony

According to Cappello, “The awards are very important for the SC conference series. They celebrate the best and the brightest of High Performance Computing [HPC].  The selection of the finalists and winners follow a very strict and codified process, involving many members of the program committee.”

SC15 Award Co-Chairs were Padma Raghavan and Franck Cappello.

He continued, “Awards are not just plaques or certificates. They define excellence. They set the bar for the years to come. They are a very powerful inspiration for young and senior researchers.”

Raghavan added that even being an award finalist at SC15 is already an achievement in itself. Following is a brief summary of some of the SC15 award winners.

SC15 Student Cluster Competition
The Student Cluster Competition is comprised of two awards: the first for the Highest LINPACK and the 2nd for the Overall Winner. These awards showcase student expertise in a friendly yet spirited competition.   It’s a non-stop, real-time, 48-hour challenge where students race to assemble a small cluster at SC15 to demonstrate the greatest sustained performance across a series of applications.

The students partner with vendors to design and build a cutting-edge cluster from commercially available components, not to exceed a 3120-watt power limit and work with application experts to tune and run the competition codes.  The Student Cluster competition is supported by Allinea and Schlumberger.

The first Student Cluster Competition award - Highest LINPACK Benchmark - went to Team TUMuch Phun, Technische Universität from München, Germany.

Australian Teens Pick Up Supercomputing Knowledge, Souvenirs on Trip to SC15

The Australian group visits the U.S. Department of Energy booth at SC15.

Eight students from three specialized science schools in eastern Australia spent a week at the SC15 conference in Austin, Texas, with the goal of bringing home more than the usual conference swag -- they came looking for information that will help them with computing projects at their schools and experiences that will spur their classmates’ interest in high performance computing.

The students were selected from the Queensland Academy of Science, Mathematics and Technology (QASMT), and the Faith Lutheran College, both in Brisbane, and the John Monash Science School in Melbourne. The students, all but one are in their 10th school year, were part of a program created several years ago by Prof. David Abramson of the University of Queensland.

“A big highlight for me was a panel presentation on post-Moore’s Law looking at digital, quantum and neuromorphic computing from the perspectives of different scientists,” said Dylan Sanusi-Goh of the John Monash Science School (JMSS). “I also went to a Microsoft talk on quantum programming and then they walked me through how to do it. Here you get to do something you couldn’t do otherwise.”

Paro Mitchell of JMSS said she was interested in how computers are getting much faster, but also wanted to know what will happen after Moore’s Law no longer applies, and the doubling of computing power per processor every 18 months which has driven the industry for decades comes to an end. “Supercomputers are such a great technology and I wanted to know what we are using it for.”

One area of research benefiting from supercomputing -- the merging of black holes, their interactions and the gravitational waves that are generated caught the imagination of Olivia MacKenzie of the Queensland Academy.

Jess Woolley of JMSS said that although she hasn’t done any programming, she was learning a lot as the week progressed. At a visit to the nearby Texas Advanced Computing Center, she was excited to see an actual supercomputer and “how big and how loud they are, and see what’s inside of them.”

And learning about a wide range of science disciplines, possibilities and tools was one of the goals of the trip, said teacher Robyn Simpson of QASMT.

Linda McIver, a teacher at JMSS, said the students were selected partly for what they would bring back to get their schools excited about computing.

And the student have clear projects at their home institutions. At each of the three schools, they are installing sensors to measure different conditions in the buildings to make them both more efficient and more comfortable.

Jack Stubbs of the Queensland Academy said his group is rolling out eight sensors to help detect when and where the lights, air conditioning and heating should be on or off, “so we can be more eco-friendly.”

Sanusi-Goh said his group is installing sensors to measure light, sound, temperature and humidity in their school to improve future classroom design. His school consists of one building with three levels, and often the lower one is too cold while the top floor is too warm.

Woolley added that her group is interested in developing a system to better regulate classroom temperatures, which are set to 23 degrees Celsius, but the current system doesn’t take into account the effects of room occupancy.

Travis Jacob, the lone 11th year student in the group, and schoolmate Harrison Cook are using a few sensors to measure carbon dioxide levels to see how they rise and fall during the day at the Faith Lutheran College. They want to see if CO2 levels can be used to indicate room occupancy.

Teacher Stephen Blair of  Faith Lutheran College said the projects help show the students the value to solid data when making their cases about classroom conditions to school administrators and pointing out ways to improve their environments.

The students received travel support from Monash University, the University of Queensland, their schools and they have corporate sponsorship from SGI and ScaleMP.

On Evolving Network Security for a Research and Enterprise Network

SC15 security technology racks with help from Dell,
Gigamon, Reservoir Labs, Splunk, and Verisign.

With more than 12,000 researchers, students, professionals, and vendors attending the conference on high performance computing, networking, storage and analysis conference, better known as SC, SC’s internet, SCinet, has to be at the forefront of network security research and implementations to stay ahead of the game on viruses, trojans, denial of service and other forms of compromise.

As the backbone of data communications for SC, SCinet supports high-bandwidth demos, HPC workshops, classrooms, and thousands of conference attendees accessing the network at any given point. With network traffic from the exhibit floor, wireless and external network traffic, there are many opportunities for the network to be compromised. SCinet’s Network Security team works to develop novel strategies to protect the integrity of the network.

“The Network Security team has transitioned from using signatures to detect single instances of malicious activity in the network to performing behavioral analytics, which track the overall patterns of security threats,” says Jeff Boote, Technical Staff at Sandia National Laboratories and co-lead for the SCinet Network Security team. “We started using these security algorithms to detect malicious hosts on the network about 2-3 years ago to be more proactive and evolve with the security trends.”

One reason for major changes in the current security strategy is the dramatic increase in network traffic at the conference. Carrie Gates, Chief Security Scientist at Dell Research and Co-lead for the Network Security team, estimates that the amount of traffic that they monitor is two to three orders of magnitude greater than the monitored traffic three years ago.

“We went from 2 10-gigabit taps (20-gigabit aggregate) in 2011, to 31 taps with 580-gigabit aggregate in 2015. With an expected 5000 simultaneous hosts on the Wi-Fi alone, on an open network that is only up for one to two weeks, the Network Security team must find novel ways to prevent malicious activity on the network,” says Gates.

Working with vendors and partners, the SCinet team integrates the technologies to monitor for harmful network traffic, detect and prevent compromised systems, and mitigate the effects of compromised systems.

Over the last three years, SCinet has used Gigamon to help monitor and secure its network operation centers and Internet access gateway. Gigamon acts as a type of mirror, allowing the Network Security team to peer into network traffic and observe a copy of the activity going through the gateway.  This traffic is being analyzed by technologies such as the Dell Firewall Sandwich, which provides high-speed deep packet inspection for malicious security events.

SCinet also serves as a research testbed for the network security.

“Back in 2000, the intrusion detection system, Bro, was being developed by Berkeley Lab and ICSI. SCinet was used as a place to test their technology on a network that is both production and research oriented,” says Gates. “It’s a balance here. SCinet provides the protection grade security of a full production network, while at same time working with technology experts who want to test new features. We’re able to provide both on SCinet. We provide production level network security while allowing for research innovation.”

One SCinet partner, Reservoir Labs, began as a SCinet Sandbox (now called Network Research Exhibition) project and is now an integral part of security architecture. Reservoir uses Bro technology under the covers to both log and analyze activity on the network.  Like Bro, Reservoir used SCinet to test the high-speed analysis features of their product while also providing production-level stability and results.

While SCinet has done behavior-based analysis of security data within a research context for more than a decade, these techniques are becoming ever more popular in day-to-day network operations. To fulfill that role in 2015, SCinet is using Splunk to aggregate the security events from Gigamon, Reservoir, and Dell SonicWALL, along with intelligence data from Verisign’s iDefense, to look for suspicious behaviors in network traffic.

This year, SCinet has over $5,000,000 in vendor loaned technology for network security.

The SC15 SCinet Network Operating Center brining in 1.62 Terabits per second
of network bandwidth.

We want to thank all the vendors and researchers over the years for engaging with SCinet and allowing us to explore the boundaries of security technologies. We look forward to seeing you at SC16!
