Scalable PGAS Metadata Management on Extreme Scale Systems
Found in: 2013 13th IEEE/ACM International Symposium on Cluster, Cloud and Grid Computing (CCGrid)
By Daniel Chavarria-Miranda,Khushbu Agarwal,T.P. Straatsma
Issue Date:May 2013
pp. 103-111
Programming models intended to run on exascale systems have a number of challenges to overcome, specially the sheer size of the system as measured by the number of concurrent software entities created and managed by the underlying runtime. It is clear from...
 
Implementing High Performance Remote Method Invocation in CCA
Found in: Cluster Computing, IEEE International Conference on
By Jian Yin,Khushbu Agarwal,Manoj Krishnan,Daniel ChavarrĂ­a-Miranda,Ian Gorton,Tom Epperly
Issue Date:September 2011
pp. 547-551
We report our effort in engineering a high performance remote method invocation (RMI) mechanism for the Common Component Architecture (CCA). This mechanism provides a highly efficient and easy-to-use mechanism for distributed computing in CCA, enabling CCA...
 
Scalable Communication Trace Compression
Found in: Cluster Computing and the Grid, IEEE International Symposium on
By Sriram Krishnamoorthy, Khushbu Agarwal
Issue Date:May 2010
pp. 408-417
Characterizing the communication behavior of parallel programs through tracing can help understand an application’s characteristics, model its performance, and predict behavior on future systems. However, lossless communication traces can get prohibitively...
 
REVEAL: An Extensible Reduced Order Model Builder for Simulation and Modeling
Found in: Computing in Science & Engineering
By Khushbu Agarwal,Poorva Sharma,Jinliang Ma,Chaomei Lo,Ian Gorton,Yan Liu
Issue Date:April 2013
pp. 1
Many science domains need to build computationally efficient and accurate representations of high fidelity, computationally expensive simulations known as reduced order models. This paper presents the design and implementation of a novel reduced-order mode...
 
Design and implementation of "many parallel task" hybrid subsurface model
Found in: Proceedings of the 2011 ACM international workshop on Many task computing on grids and supercomputers (MTAGS '11)
By Jared M. Chase, Karen L. Schuchardt, Todd O. Elsethagen, Bruce J. Palmer, Khushbu Agarwal, Timothy D. Schiebe
Issue Date:November 2011
pp. 25-32
Continuum scale models have been used to study subsurface flow, transport, and reactions for many years. Recently, pore scale models, which operate at scales of individual soil grains, have been developed to more accurately model pore scale phenomena, such...
