Scalable parallel I/O alternatives for massively parallel partitioned solver systems
Found in: Parallel and Distributed Processing Workshops and PhD Forum, 2011 IEEE International Symposium on
By Jing Fu, Ning Liu,Onkar Sahni,Kenneth E. Jansen,Mark S. Shephard,Christopher D. Carothers
Issue Date:April 2010
pp. 1-8
With the development of high-performance computing, I/O issues have become the bottleneck for many massively parallel applications. This paper investigates scalable parallel I/O alternatives for massively parallel partitioned solver systems. Typically such...
 
Bringing HPC to Engineering Innovation
Found in: Computing in Science & Engineering
By Mark S. Shephard,Cameron Smith,John E. Kolb
Issue Date:January 2013
pp. 16-25
Although there's a widespread belief that the effective application of high-performance computing will dramatically increase industrial innovation, progress in this area has been slow and limited because of a combination of technical and economic impedimen...
 
Scalable implicit finite element solver for massively parallel processing with demonstration to 160K cores
Found in: SC Conference
By Onkar Sahni, Min Zhou, Mark S. Shephard, Kenneth E. Jansen
Issue Date:November 2009
pp. 1-12
Implicit methods for partial differential equations using unstructured meshes allow for an efficient solution strategy for many real-world problems (e.g., simulation-based virtual surgical planning). Scalable solvers employing these methods not only enable...
 
A Language-Independent API for Unstructured Mesh Access and Manipulation
Found in: High Performance Computing Systems and Applications, Annual International Symposium on
By Carl Ollivier-Gooch, Lori Freitag Diachin, Mark S. Shephard, Timothy Tautges
Issue Date:May 2007
pp. 22
Software for numerical solution of partial differential equations requires accessing, manipulating, and often modifying information about the geometry of the computational domain, the mesh used for the simulation, and discrete data stored on that mesh. Typ...
 
An Interoperable, Data-Structure-Neutral Component for Mesh Query and Manipulation
Found in: ACM Transactions on Mathematical Software (TOMS)
By Carl Ollivier-Gooch, Jason Kraftcheck, Lori Diachin, Mark Miller, Mark S. Shephard, Timothy Tautges, Vitus Leung, Xiaojuan Luo
Issue Date:September 2010
pp. 1-28
Much of the effort required to create a new simulation code goes into developing infrastructure for mesh data manipulation, adaptive refinement, design optimization, and so forth. This infrastructure is an obvious target for code reuse, except that impleme...

Subdomain communication to increase scalability in large-scale scientific applications
Found in: Proceedings of the 23rd international conference on Supercomputing (ICS '09)
By Aleksandr Ovcharenko, Christopher D. Carothers, Kenneth E. Jansen, Mark S. Shephard, Onkar Sahni
Issue Date:June 2009
pp. 1-1
This paper introduces a general-purpose communication package built on top of MPI which is aimed at improving inter-processor communications for parallel computations characterized by large numbers of messages. The current library provides a utility for su...
