碩士 === 崑山科技大學 === 電機工程研究所 === 96 === In the last few years, because the computing efficiency of personal computers has been increasing and the computer network technology has progressed quickly, PC clusters are used in many fields and various kinds of management software are produced. We apply the parallel virtual machine to the discrete wavelet transform in this thesis. Two PCs are made into one PC cluster, and Linux is used for the operating system. Then we can get a high performance computation, and the discrete wavelet transform program is developed with C language at the cluster. The power signals are tested by the proposed method. In order to exhibit the efficiency of this study, we compare the running time of a single PC and a PC cluster. The test results reveal that the method can improve the time consuming of the discrete wavelet transform.
