Performance of multicomputers using high-speed communication links
(1993)
This thesis presents the results of a simulation study of the performance of a message-passing multicomputer using high-speed point-to-point communication links. The multicomputer system consists of IBM RS/6000 machines ...
The acquisition, signal processing and analysis of epicardial surface electrograms from rabbit heart
(1989)
The activation sequence on the epicardial surface of the in vivo rabbit ventricle has been recorded and analyzed under conditions of normal sinus rhythm and controlled hemodynamic load. Data for the analysis was gathered ...
Performance prediction of packet switched multistage interconnection networks in an execution-driven environment
(1990)
This thesis studies the performance of multistage interconnection networks (MINs) using execution-driven simulation. The networks were studied with varying network configurations, numbers of inputs and outputs of the network ...
Optimal control of a class of real-time computational systems
(1991)
In many computational systems, tasks comprising numerical or symbolic data arrive at a processor periodically. Processing of the $i\sp{th}$ task has to stop before processing of the ($i$ + 1)$\sp{th}$ task begins, causing ...
A software simulation testbed for CDMA wireless communication systems
(1999)
This thesis develops a software wireless communication testbed which simulates a Code Division Multiple Access (CDMA) link. CDMA is a popular technology in cellular systems due to its superior capacity and performance. The ...
Theory and applications of the shift-invariant, time-varying and undecimated wavelet transforms
(1995)
In this thesis, we generalize the classical discrete wavelet transform, and construct wavelet transforms that are shift-invariant, time-varying, undecimated, and signal dependent. The result is a set of powerful and efficient ...
Efficient simulation of simple instruction set array processors
(1990)
Simple instruction set array processors are groups of regularly connected processors with small instruction sets and local memories. The processors are augmented by built-in communication instructions. Because of the ...
Message passing versus distributed shared memory on networks of workstations
(1995)
We compared the message passing library Parallel Virtual Machine (PVM) with the distributed shared memory system TreadMarks, on networks of workstations. We presented the performance of nine applications, including Water ...
Competitive prefetching and buffer management for parallel I/O systems
(1997)
In this thesis we study prefetching and buffer management algorithms for parallel I/O systems. Two models of lookahead, global and local, which give limited information regarding future accesses are introduced. Two ...
ParaView: Performance debugging through visualization of shared data
(1994)
Performance debugging is the process of isolating and correcting performance problems in an otherwise correct parallel program. Problems not immediately visible to the parallel programmer often lead to poor application ...
