Development of a parallel SAR processor on a Beowulf cluster
… distributed in memory over the nodes in the cluster. This was successfully achieved using a in-place method, thus saving valuable memory resources. Once the parallel processor was implemented some timing tests were performed, yielding a maximum speedup factor of 6.2 for an 8 slave processor …

Speedup of MCNP(X) parallel KCODE execution via communication algorithm development and Beowulf Cluster optimization
… The first approach is assembly of a low cost Beowulf Cluster for parallel computation. The first half describes the MIT Nuclear Engineering Department's Beowulf Cluster, Echelon, as a prototype. Echelon is a low cost, 30 CPIJ, disk-less Debian Linux Beowulf Cluster. A user's manual is …

A Descriptive Performance Model of Small, Low Cost, Diskless Beowulf Clusters
<p>Commodity supercomputing clusters known as Beowulf clusters, have become a low cost alternative to traditional supercomputers. Beowulf clusters combine inexpensive computers and specialized software to achieve supercomputing power. The processing nodes in a diskless Beowulf cluster do not have a …

Parallelization of ECG template-based abnormality detection
… in the data. The processing is done on a Linux Beowulf Cluster using the standardized Message Passing Interface (MPI) libraries. In the thesis, the results of four different parallel approaches are compared, and their performance is evaluated.

An R*-Tree Based Semi-Dynamic Clustering Method for the Efficient Processing of Spatial Join in a Shared-Nothing Parallel Database System
… the data set across several nodes of a cluster and executing queries across these nodes in parallel. This document discusses a new parallel algorithm that implements the spatial join in an efficient manner. This algorithm is compared to an existing parallel spatial-join algorithm, the …

Development of multifunctional software for evaluating the photonic properties of new dielectric composite geometries
… solutions to be obtained quickly using a beowulf cluster. An extension to the basic FDTD plane wave source was derived, allowing for the creation of angled, periodic, unidirectional plane waves on a square grid. 1D photonic crystal stacks were arranged in a square array and it was …

Threaded WARPED : An Optimistic Parallel Discrete Event Simulator for Cluster of Multi-Core Machines
… and many-core processors suitable for use in Beowulf clusters provides an opportunity for PDES execution on a platform containing both shared memory and distributed memory parallelism. This thesis explores the migration of an existing PDES simulation kernel called WARPED to a Beowulf Cluster …

Global Optimization of Transmitter Placement for Indoor Wireless Communication Systems
… ray tracing modeler running on a 200-node Beowulf cluster of Linux workstations, and surrogate functions for a WCDMA (wideband code division multiple access) simulator are also used to estimate the channel performance. Any component failure of this large computation would abort the entire …

Scalable parallel simulation of small-scale structures in cold dark matter
… (P³M) algorithm for distributed memory clusters. The llp3m-hc code uses a hybrid method for both computation and domain decomposition. Long-range forces are computed using a Fourier transform gravity solver on a regular mesh; the mesh is distributed across parallel processes using a …

Black Hole Accretion Systems
… performing numerical simulations on our group's Beowulf computer clusters, which I designed and constructed. For about $50,000, one can buy a private cluster of computers that will provide as much computing power as today's typical time-shared ""supercomputer."" I give an account of the …
