Abstract: In this paper, we have implemented and evaluated the performance of local predecimation with range index communication parallelization strategy for fractal image compression on a beowulf cluster of workstations. The strategy effectively balances the load among workstations. We have evaluated the execution time of LPRI, varying the number of workstations and user-specified root mean square error. We have also reported the measured speedup and worker idle time of LPRI parallelization.
Keywords: Load balancing, task partitioning, parallelization, fractal image compression.
