Pipeline Implementation of Cellular Automata for Structural Design on Message-Passing Multiprocessors
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2003), TR-03-28
The inherent structure of cellular automata is trivially parallelizable and can directly benefit from massively parallel machines in computationally intensive problems. This paper presents both synchronous and pipeline ...
Parameter Estimation for a Mathematical Model of the Cell Cycle in Frog Eggs
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2002-08-01), TR-02-18
Parameter values for a kinetic model of teh nuclear replication-division cycle in frog eggs are estimated by fitting solutions of the kinetic equations (nonlinear ordinary differential equations) to a suite of experimental ...
Optimization and Blending of Composite Laminates Using Guide based Genetic Algorithms
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2003), TR-03-11
Composite panel structure optimization is commonly decomposed into panel optimization subproblems, with specified local loads, resulting in manufacturing incompatibilities between adjacent panel designs. A new method ...
Multidisciplinary Design Optimization with Quasiseparable Subsystems
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2002), TR-02-09
Numerous hierarchical and nonhierarchical decomposition strategies for the optimization of large scale systems, comprised of interacting subsystems, have been proposed. With a few exceptions, all of these strategies have ...
Identifying Native Applications with High Assurance
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2011), TR-11-20
The work described in this paper investigates the problem of identifying and deterring stealthy malicious processes on a host. We point out the lack of strong application iden- tication in main stream operating systems. ...
From Cluster to Grid: A Case Study in Scaling-Up a Molecular Electronics Simulation Code
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2002-11-01), TR-02-27
This paper describes an ongoing project whose goal is to significantly improve the performance and applicability of a molecular electronics simulation code. The specific goals are to (1) increase computational performance ...
Parallel Load Balancing Strategies for Ensembles of Stochastic Biochemical Simulations
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2010-12-01), TR-10-17
The evolution of biochemical systems where some chemical species are present with only a small number of molecules, is strongly influenced by discrete and stochastic effects that cannot be accurately captured by continuous ...
A Pluggable Framework for Lightweight Task Offloading in Parallel and Distributed Computing
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2008), TR-08-27
Multicore processors have quickly become ubiquitous in supercomputing, cluster computing, datacenter computing, and even personal computing. Software advances, however, continue to lag behind. In the past, software designers ...
Taming Multi-core Parallelism with Concurrent Mixin Layers
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2008), TR-08-22
The recent shift in computer system design to multi-core technology requires that the developer leverage explicit parallel programming techniques in order to utilize available performance. Nevertheless, developing the ...
A fully Distributed Parallel Global Search Algorithm
(Department of Computer Science, Virginia Polytechnic Institute & State University, 2000), TR-00-06
The n-dimensional direct search algorithm DIRECT of Jones,Perttunen, and Stuckman has attracted recent attention from the multidisciplinary design optimization community. Since DIRECT only requires function values (or ...
