SC15 Awards Ceremony Recap: Part Two

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.

        The Overall Student Cluster Competition winner was determined based on a combined score for correctly completed workload, benchmark performance, demonstrated understanding of architecture and performance through profiling and analysis, and interviews. This year’s winner was Team Diablo from Tsinghua University in China.

        Technical Papers Program
        Jeffrey S. Vetter, SC15 Technical Program Chair, presents interesting data from this year’s submissions during the SC15 awards ceremony in Austin, Texas.

        The Technical Papers Program is one of SC’s most valued components.  Each year SC receives submissions of original research that introduce new ideas to the field and stimulate future trends in HPC.  As in previous years, it was a tough competition, with 361 paper submissions covering a wide range of research interests and topics.

        The committee met for two days in June to review the Papers. At the conclusion of the meeting, the committee had accepted 78 papers, which is a 22 percent acceptance rate.  Of the 78 papers, nine have been selected as finalists for the Best Paper and Best Student Paper awards.

        Please note,  all technical papers are available at the ACM Digital Library and can be accessed by clicking here.

        Best Student Paper

        "Parallel Distributed Memory Construction of Suffix and Longest Common Prefix Arrays” by Patrick Flick and Srinivas Aluru was selected as the SC15 best student paper.

        Patrick Flick’s and Srinivas Aluru’s winning paper proposes a novel algorithm for the suffix array problem. The performance results are very impressive and demonstrate a hundred fold improvement over existing methods. The algorithm itself has a potential broad impact on the field of genomics.

        The three other finalists were:
        • Adaptive and Transparent Cache Bypassing for GPUs - with Ang Li from Eindhoven University of Technology as the lead author.
        • A Case for Application-Oblivious Energy - Efficient MPI Runtime- with Akshay Venkatesh - Ohio State University as the lead author.
        • GraphReduce: Processing Large-Scale Graphs on Accelerator - Based Systems - with Dipanjan Sengupta - Georgia Institute of Technology as the lead author

        Best Overall Paper
        The SC15 Best Paper, ”ScaAnalyzer — A Tool to Identify Memory Scalability Bottlenecks in Parallel Programs” by Xu Liu and Bo Wu.

        Xu Liu’s and Bo Wu’s winning paper proposes methods and tools that isolate the causes of memory bottlenecks in both hardware and software in advanced computing systems. The committee felt the fundamental contributions address the memory wall problem and could have wide applicability in software development at Exascale.

        The Best Paper authors (with certificates from left) Bo Wu and Xu Liu receive their awards from members of the SC15 Awards Committee who are (from left) Padma Raghavan, Eva Deelman and José Moreira, co-chairs of the SC15 Technical Papers Committee, and Franck Cappello.
