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 ...
Implementation of multiple-corrections and presolve enhancement in the interior-point linear programming code LIPSOL
(1999)
Multiple correction was introduced by Gondzio (5) to accelerate the convergence of iterates generated by primal-dual interior-point algorithms for linear programming. In this work, we implement the multiple correction ...
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 ...
A new approach to slant stack processing: An X-window (OSF/motif) project
(1992)
A new definition for slant stack and inversion has been formulated. The different p ranges with different frequencies in the forward slant stack provide accurate reconstruction of the original data. The computing time is ...
DMO on irregularly spaced seismic data (dip moveout)
(1993)
Irregularly spaced seismic data have uneven distribution of trace midpoint density on the half-offset (h) versus common-midpoint (y) space. The deviation from uniformity disrupts the cancellation and reinforcement processes ...
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 techniques for n-body simulation on distributed memory architectures
(1999)
High Performance Fortran (HPF) provides a high-level model for expressing parallel programs. However, the efficiency of HPF as an implementation vehicle for irregular applications is still largely unproven. While recent ...
Interprocedural array side effect analysis
(1994)
In the absence of better information worst case assumptions must be made for the side effects of calls on arrays. Interprocedural array side effect analysis computes the side effects of calls on array variables. The results ...
