LSU CCT Receives Top Paper Award by HPDC

A research paper whose co-authors include LSU's Gabrielle Allen, Werner Benger, Andrew Merzky, and Ed Seidel has been named by the International ACM Symposium on High-Performance Parallel and Distributed Computing (HPDC) as one of the top 20 papers in the past 20 years of publications.  Gabrielle Allen is associate professor of LSU's Department of Computer Science and Center for Computation & Technology (CCT), Werner Benger and Andre Merzky are research scientists at the LSU CCT; and Ed Seidel is professor of the LSU Department of Physics & Astronomy and former director of the LSU CCT.

HPDC is the premier computer science conference for presenting new research related to high-performance parallel and distributed systems used in both science and industry.  Since its inception, HPDC has been at the center of new discoveries in systems such as clusters, grids, clouds, and parallel and multicore computers.

Published in 2000, "The Cactus Code: A Problem Solving Environment for the Grid" explained how the intensive computing requirements of physics applications using the Cactus Code encourage the use of distributed and metacomputing, described the development and experiments which were performed with Cactus, and detailed how its design made it an ideal application test bed for Grid computing.

Originating in the academic research community, Cactus has been developed and used over many years by a large, international collaboration of physicists and computational scientists.  Specifically, Cactus is an open-source problem-solving environment designed for scientists and engineers.  Its modular structure facilitates parallel computation across different architectures and collaborative code development among different groups. 

The Cactus group at CCT continue to innovate in software that advances both physics and computer science, and in particular lead the development of the Einstein Toolkit to provide a cutting edge toolkit for relativistic astrophysics which has been adopted by some 60 groups around the world. 

The papers were nominated by members of the HPDC community at large, and a special committee narrowed the list to the best 20.  A special edition issue containing the 20 papers will be distributed at the HPDC's 2012 meeting, to be held this summer in the Netherlands. 

G. Allen, W. Benger, T. Goodale, H.C. Hege, G. Lanfermann, A. Merzky, T. Radke, E. Seidel, and J. Shalf, The cactus code: “A Problem Solving Environment for the Grid,” High-Performance Distributed Computing, 2000. Proceedings. The Ninth International Symposium on, IEEE, 2000, pp. 253–260.

Pats on the Back:

  • Peter Diener, et al., were published in Physical Review Letters, one of the world's most prestigious publications in physics, providing weekly coverage on major advances in physics and cross disciplinary developments.
    • Peter Diener, Ian Vega, Barry Wardell and Steven Detweiler, Phys. Rev. Lett. 108, 191102 (2012), "Self-Consistent Orbital Evolution of a Particle around a Schwarzschild Black Hole"
    • The URL to access the paper is: http://link.aps.org/doi/10.1103/PhysRevLett.108.191102
    • In the article they perform, for the first time, an orbital evolution of a scalar charge around a non-rotating black hole taking into account the interaction of the scalar charge with it's own field in a self-consistent way.
  • Susanne Brenner was one of the invited one-hour speakers at the 2012 John H. Barrett Memorial Lectures at the University of Tennessee at Knoxville, May 9-11.  The topic for this year's lectures was "Recent Developments in Discontinuous Galerkin Finite Element Methods for Partial Differential Equations".
  • One of the main projects connected to the Cactus group at CCT, the Einstein Toolkit, just published it's main overview paper in Classical and Quantum Gravity: "The Einstein Toolkit: a community computational infrastructure for relativistic astrophysics." The paper is accessible via http://iopscience.iop.org/0264-9381/29/11/115001/ and was a major effort from scientists at six institutions worldwide. A quite unique feature in this field of science is that all information used for examples and simulations within the publication is freely available. This includes the complete source code and the exact parameters used.  Every simulation can be repeated by an interested reader, which was in fact done by one of the referees.
  • Congrats to the following CCT students graduating this semester:
    • Graduate Students:  Raj Nagaraju Palavarapu
    • Undergraduate Students:  Philip LeBlanc
  • Congrats to Adam and Katie Yates on the birth of their daughter Natalie Joy Yates, 1:13 AM, May 15, 2012!
