The effects of cache coherence on the performance of parallel PDE algorithms in multiprocessor systems
The advent of parallel processing systems has resulted in the potential for increased performance over traditional uniprocessor systems. However, while there has been significant advances in developing these systems, ...
Theory and applications of the shift-invariant, time-varying and undecimated wavelet transforms
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 VLSI architectures for matrix factorizations
The SVD (Singular Value Decomposition) is a critical matrix factorization in many real-time computations from an application domain which includes signal processing and robotics; and complex data matrices are encountered ...
Performance analysis of parallel I/O models for external mergesort
Since the I/O subsystem is the bottleneck in external mergesort, I/O parallelism can result in substantial performance improvements. Concurrency can be introduced by overlapping I/O requests at different disks, and the ...
