Exascale Computing [Guest Editorial]
Found in: Computing in Science & Engineering
By Steven Gottlieb,Thomas Sterling
Issue Date:November 2013
pp. 12-15
The guest editors discuss some recent advances in exascale computing, as well as remaining issues.
Anecdotes on Leadership Computing
Found in: Computing in Science & Engineering
By Steven Gottlieb
Issue Date:September 2014
pp. 4-6
Here, Steven Gottlieb recounts the origin of the term leadership computing, and shares stories from his computing experiences predating the introduction of the term. No names have been changed to protect the innocent, but several have been omitted to prote...
Becoming a Computational Scientist
Found in: Computing in Science & Engineering
By Steven Gottlieb
Issue Date:January 2014
pp. 4-5
Each computational scientist has a unique path that led him or her to this dynamic field. Here, Steven Gottlieb weaves his own tale, encouraging others to share their stories of how they became computational scientists, to create awareness and encourage ot...
The Fat-Link Computation on Large GPU Clusters for Lattice QCD
Found in: 2012 Symposium on Application Accelerators in High Performance Computing (SAAHPC)
By Guochun Shi,Ronald Babich,Michael A. Clark,B'lint Joo,Steven Gottlieb,Volodymyr Kindratenko
Issue Date:July 2012
pp. 1-10
Graphics Processing Units (GPU) are becoming increasingly popular in high performance computing due to their high performance, high power efficiency and low cost. In this paper, we present results of an effort to implement the fatlink computation -- an imp...
Performance Modeling and Comparative Analysis of the MILC Lattice QCD Application su3_rmd
Found in: Cluster Computing and the Grid, IEEE International Symposium on
By Greg Bauer,Steven Gottlieb,Torsten Hoefler
Issue Date:May 2012
pp. 652-659
Application performance modeling is an essential part of application and system development as HPC moves into the petascale and prepares for the exascale. However, performance modeling of parallel systems is a difficult task due to natural variations in me...
Design of MILC Lattice QCD Application for GPU Clusters
Found in: Parallel and Distributed Processing Symposium, International
By Guochun Shi,Steven Gottlieb,Aaron Torok,Volodymyr Kindratenko
Issue Date:May 2011
pp. 363-371
We present an implementation of the improved staggered quark action lattice QCD computation designed for execution on a GPU cluster. The parallelization strategy is based on dividing the space-time lattice along the time dimension and distributing the sub-...
Advancing the Cause of Computation in the Physics Curriculum
Found in: Computing in Science and Engineering
By Rubin Landau, Steven Gottlieb
Issue Date:March 2010
pp. 6-7
<p>Incorporating computational science into physics education is crucial for the future of both students and the field itself.</p>
Guest Editor's Introduction: Special-Purpose Computing
Found in: Computing in Science and Engineering
By Steven Gottlieb
Issue Date:January 2006
pp. 15-17
My awareness of special-purpose computing goes back quite a long time. In the early 1980s, my former grad-school housemate and (still) good friend Doug Toussaint worked with Bob Pearson and John Richardson on a special-purpose computer to study the Ising m...
