Patus for convenient high-performance stencils: Evaluation in earthquake simulations
Found in: 2012 SC - International Conference for High Performance Computing, Networking, Storage and Analysis
By Matthias Christen,Olaf Schenk,Yifeng Cui
Issue Date:November 2012
pp. 1-10
PATUS is a code generation and auto-tuning framework for stencil computations targeting modern multi and many-core processors. The goals of the framework are productivity and portability for achieving high performance on the target platform. Its stencil sp...
Accelerating a 3D Finite-Difference Earthquake Simulation with a C-to-CUDA Translator
Found in: Computing in Science & Engineering
By Didem Unat,Jun Zhou,Yifeng Cui,Scott B. Baden,Xing Cai
Issue Date:May 2012
pp. 48-59
GPUs provide impressive computing power, but GPU programming can be challenging. Here, an experience in porting real-world earthquake code to Nvidia GPUs is described. Specifically, an annotation-based programming model, called Mint, and its accompanying s...
Workflow-Based High Performance Data Transfer and Ingestion to Support Petascale Simulations on TeraGrid
Found in: Computational Sciences and Optimization, International Joint Conference on
By Jun Zhou, Yifeng Cui, Sashka Davis, Clark C. Guest, Philip Maechling
Issue Date:May 2010
pp. 343-347
In this paper we report on high performance data transfer and ingestion design carried out in a scientific workflow project to support Southern California Earthquake Center (SCEC) petascale simulations on TeraGrid (TG), which is conducive to utilize the gr...
Visual Insights into High-Resolution Earthquake Simulations
Found in: IEEE Computer Graphics and Applications
By Amit Chourasia, Steve Cutchin, Yifeng Cui, Reagan W. Moore, Kim Olsen, Steven M. Day, J. Bernard Minster, Philip Maechling, Thomas H. Jordan
Issue Date:September 2007
pp. 28-34
This study focuses on the visualization of a series of large earthquake simulations, collectively called TeraShake. The simulation series aims to assess the impact of Southern San Andreas Fault earthquake scenarios on Southern California. The authors discu...
Scalable Earthquake Simulation on Petascale Supercomputers
Found in: SC Conference
