Expected Values For Cache Miss Rates For A Single Trace (Technical Summary), Russell W. Quong Jul 1993

Expected Values For Cache Miss Rates For A Single Trace (Technical Summary), Russell W. Quong

Department of Electrical and Computer Engineering Technical Reports

The standard trace-driven cache simulation evaluates the miss rate of cache C on an address trace T for program P running on input data I with object-code address map M for P. We note that the measured miss rate depends significantly on the address mapping M set arbitrarily by the compiler and linker. In this paper, we remove the effect of the address-mapping on the miss rate by analyzing a symbolic trace T of basic blocks. By assuming each basic block has an equal probability of ending up anywhere in the cache,'we determine the average miss rate over all possible …


A Tutorial On Lisp Object-Oriented Programming For Blackboard Computation (Solving The Radar Tracking Problem) , P. R. Kersten, A. C. Kak Jul 1993

A Tutorial On Lisp Object-Oriented Programming For Blackboard Computation (Solving The Radar Tracking Problem) , P. R. Kersten, A. C. Kak

Department of Electrical and Computer Engineering Technical Reports

This exposition is a tutorial on how object-oriented programming (OOP) in Lisp can be used for programming a blackboard. Since we have used Common Lisp and the Common Lisp Object System (CLOS), the exposition demonstrates how object classes and the primary, before, and after methods associated with the classes can be used for this purpose. The reader should note that the different approaches to object-oriented programming share considerable similarity and, therefore, the exposition should be helpful to even those who may not wish to use CLOS. We have used the radar tracking problem as a 'medium' for explaining the concepts …

Pns Modules For The Synthesis Of Parallel Self-Organizing Hierarchical Neural Networks, Faramarz Valafar, Okan K. Ersoy Jun 1993

Pns Modules For The Synthesis Of Parallel Self-Organizing Hierarchical Neural Networks, Faramarz Valafar, Okan K. Ersoy

Department of Electrical and Computer Engineering Technical Reports

The PNS module is discussed as the building block for the synthesis of parallel, selforganizing, hierarchical, neural networks (PSHNN). The PNS consists of a prerejector (P-unit), a neural network (N-unit) and a statistical analysis unit (S-unit). The last two units together are also referred to as the NS unit. The P- and NS-units are fractile in nature, meaning that each such unit may itself consist of a number of parallel PNS modules. Through a mechanism of statistical acceptance or rejection of input vectors for classification, the sample space is divided into a number of subspaces. The input vectors belonging to …

A Neural Network Approach To Stationary Target Discrimination, Douglas J. Munro, Okan K. Ersoy May 1993

A Neural Network Approach To Stationary Target Discrimination, Douglas J. Munro, Okan K. Ersoy

Department of Electrical and Computer Engineering Technical Reports

The problem which motivated this research was that of stationary target identification (STI) with millimeter wave seekers in a heavy clutter environment. While investigating the use of neural networks to perform target discrimination phase for ST1 problem, we began to search for a method to reduce the computational overhead associated with training a neural network to recognize low probability events. Our search yielded the development of a likelihood ratio weighting function (LRWF), which is very similar to the weighting function used in importance sampling techniques employed in the simulation of digital communication systems. By incorporating the LRWF into the backpropagation …

Computing Multiple Quadratic Forms For A Minimum Variance Distortionless Response Adaptive Beamformer Using Parallelism: Analyses And Experiments, Mu-Cheng Wang, Wayne G. Nation, James B. Armstrong, Howard Jay Siegel, Shin-Dug Kim, Mark A. Nichols, Michael Gherrity

Department of Electrical and Computer Engineering Technical Reports

Data-parallel implementations of the computationally intensive task of solving multiple quadratic forms (MQFs) have been examined. Coupled and uncoupled parallel methods are investigated, where coupling relates to the degree of interaction among the processors. Also, the impact of partitioning a large MQF problem into smaller non-interacting subtasks is studied. Trade-offs among the implementations for various data-size/machine-size ratios are categorized in terms of complex arithmetic operation counts, communication overhead, and memory storage requirements. Furthermore, the impact on performance of the mode of parallelism used is considered, specifically, SIMD versus MIMD versus SIMD/MIMD mixed-mode. From the complexity analyses, it is shown that …

On A Quantitative Model Of Dynamic System Reconfiguration Due To A Fault, Gene Saghi, Howard Jay Siegel, Jose A. B. Fortes Apr 1993

On A Quantitative Model Of Dynamic System Reconfiguration Due To A Fault, Gene Saghi, Howard Jay Siegel, Jose A. B. Fortes

Department of Electrical and Computer Engineering Technical Reports

The use of dynamic reconfiguration has been proposed to tolerate faults in large-scale partitionable parallel processing systems. If a processor develops a permanent fault during the execution of a task on a submachine A, three recovery options are migration of the task to another submachine, task migration to a subdivision of A, and redistribution of the task among the fault-free processors in A. Quantitative models of these reconfiguration schemes are developed to consider what information is needed to make a choice among these methods for a practical implementation. It is pointed out that in certain situations collecting precise values for …

A Parallel Implementation Of Backpropagation Neural Network On Maspar Mp-1, Faramarz Valafar, Okan K. Ersoy Mar 1993

A Parallel Implementation Of Backpropagation Neural Network On Maspar Mp-1, Faramarz Valafar, Okan K. Ersoy

Department of Electrical and Computer Engineering Technical Reports

One of the major issues in using artificial neural networks is reducing the training and the testing times. Parallel processing is the most efficient approach for this purpose. In this paper, we explore the parallel implementation of the backpropagation algorithm with and without hidden layers [4][5] on MasPar MP-I. This implementation is based on the SIMD architecture, and uses a backpropagation model which is more exact theoretically than the serial backpropagation model. This results in a smoother convergence to the solution. Most importantly, the processing time is reduced both theoretically and experimentally by the order of 3000, due to architectural …
