IPDPS 2010 KEYNOTE TALKS

Due to flight cancellations, Kunle Olukotun and Peter Sanders, two of our scheduled keynote speakers, were not able to reach Atlanta. However, two distinguished speakers, Srinivas Aluru and Arnold Rosenberg, will address the IPDPS community in their place, along with our third keynote speaker, Burton Smith. Please look for Kunle and Peter at a future IPDPS!

Wednesday morning keynote talk

• Srinivas Aluru, Iowa State University
• Title:
  The new era in genomics: Opportunities and challenges for high performance computing
• Abstract: For nearly three decades, the Sanger method of reading one DNA sequence at a time served as the mainstay of genomics research. The advent of high-throughput short read DNA sequencing technology is enabling revolutionary advances in life sciences by providing an inexpensive way to sample genomes at high coverage. This is causing a paradigm shift in individual genome sequencing, sequencing unknown genomes and metagenomes, and generating transcript expression profiles. The rate of data generation is handily outpacing Moore's law, with tenfold increase per year. This talk will outline the computational challenges in exploiting high-throughput sequencing technology, and the role of parallel methods as we transition to this new era.
• Brief Biography: Srinivas Aluru is the Mehl Professor of Computer Engineering at Iowa State University, and the Bajaj Chair Professor of Computer Science and Engineering at Indian Institute of Technology Bombay. Earlier, he served as Chair of Iowa State's Bioinformatics and Computational Biology program, and held faculty positions at New Mexico State University and Syracuse University. Aluru conducts research in high performance computing, bioinformatics and systems biology, combinatorial scientific computing, and applied algorithms. He pioneered the development of parallel methods in computational biology, and contributed to the sequencing and analysis of the maize genome. He is a Fellow of the IEEE, and is a recipient of the NSF Career award, IBM faculty award, and Swarnajayanti fellowship from the Government of India.

Thursday morning keynote talk

  IC-Scheduling Theory: A New Scheduling Paradigm for Task-Hungry Platforms
• Abstract: Technological and economic developments have created/enabled a variety of task-hungry computing platforms. Notable among these are "massively multi-core" computing systems and a modality of Internet-based computing (IC) within which the owner of a large, typically compute-intensive, computation enlists remote clients to "collaborate" in performing the computation. Let us talk only about IC, for definiteness. When one's computation comprises only independent tasks, the temporal unpredictability of IC-communication is over the Internet; computing is by clients who arrive unpredictably and are typically not dedicated to the computation-is at worst an annoying source of slowdown. But, when the computation's tasks have interdependencies that prioritize their execution, temporal unpredictability can confute attempts to benefit from "parallel" execution of tasks and can even cause a computation to stall for lack of unallocated eligible tasks. In a series of papers, we have proposed a new scheduling paradigm that aims to respond to the new challenges of IC. Faced with the impossibility (due to temporal unpredictability) of scheduling to accommodate "critical paths" in a computation, we seek to schedule in a way that always renders as many tasks as possible eligible for allocation to clients. This goal: (a) maximizes the utilization of available clients and (b) minimizes the likelihood of a computation's stalling. We have formalized this scheduling problem and, under idealized assumptions, have developed the beginnings of an algorithmic theory for scheduling complex computations for IC. We describe the concepts underlying the new theory and the algorithms that emerge from them, illustrated via several familiar computations and computational paradigms. We describe simulation experiments whose results suggest that the theory's schedules have a measurable benign effect on "real" Internet-based computing.
• Brief Biography: Arnold L. Rosenberg holds the rank of Research Professor in the ECE Department at Colorado State University (with a secondary appointment in Computer Science) and of Distinguished University Professor Emeritus in the Computer Science Department at the University of Massachusetts Amherst. Prior to joining UMass, Rosenberg was a Professor of Computer Science at Duke University from 1981 to 1986, and a Research Staff Member at the IBM Watson Research Center from 1965 to 1981. He has held visiting positions at Yale University and the University of Toronto. He was a Lady Davis Visiting Professor at the Technion (Israel Institute of Technology) in 1994, and a Fulbright Senior Research Scholar at the University of Paris-South in 2000. Rosenberg's research focuses on developing algorithmic models and techniques to exploit the new modalities of "collaborative computing" (wherein multiple computers cooperate to solve a computational problem) that result from emerging technologies, especially Internet-based computing. Rosenberg is the author or coauthor of more than 170 technical papers on these and other topics in theoretical computer science and discrete mathematics. He is the coauthor of the research book "Graph Separators, with Applications" and the author of the textbook "The Pillars of Computation Theory: State, Encoding, Nondeterminism"; additionally, he has served as coeditor of several books. Dr. Rosenberg is a Fellow of the ACM, a Fellow of the IEEE, and a Golden Core member of the IEEE Computer Society. Rosenberg received an A.B. in mathematics at Harvard College and an A.M. and Ph.D. in applied mathematics at Harvard University.

Message from IPDPS 2010 General Chair (chair@ipdps.org)

To authors and attendees of IPDPS 2010 papers who are affected by the volcanic eruption in Iceland, we regret the untimely interruption of air travel between Europe and the US, but hope that some of you will have the opportunity to travel in time to participate in your scheduled session or workshop.

I encourage those unable to attend to find someone who might present for you. On your own, you are welcome to make such arrangements, including furnishing slides to your substitute presenter or at least arranging for someone to attend your session to represent you and report on your behalf.

• For authors with papers in workshops, you should contact your workshop organizers to make any arrangement for participating remotely or having someone present for you.
• For PhD Forum participants, since your poster also cannot travel, we will arrange to post your 4-page paper.
• For authors of regular conference papers, you should contact me at chair@ipdps.org and in your email specify your session and paper and whether you have arranged for someone to attend in your place.

We will post regular updates to help facilitate alternative ways of participating. As a first step, we have posted the program book pdf (best read two-up) which gives the full program for all papers and speakers who are part of IPDPS 2010. This may be a useful tool along with the posted abstracts for all papers in identifying someone to present for you. Stay tuned.
