ABSTRACT
Wavelets transform, especially discrete wavelets transform (DWT) is an important tool for many applications. This paper describes one parallel implementation of simplest wavelet transform, namely Haar transform. A theoretical and experimental analysis of this parallel implementation in a cluster environment is also described. Implementation is based on hypercube architecture and for experimental results, a simple cluster computer (with Red Hat Enterprise 4 and OSCAR 4.2 in computer network with 8 PCs) is used. The programming language used here is C++ with LAM MPI 2 paradigm. The results show the impact of computation and communication on the parallel implementation and its comparison with one process implementation which time is O(n).
