Abstract

The supercomputers built with processors based on CBEA architecture are relatively new and there are fewer applications optimized for this type of system. In this article, we propose to use computing resources provided by a CBEA-based cluster by parallelization and optimization of an algorithm for classification of a large dataset. In order to analyze the proposed methods of parallelization, the algorithm is executed on a CBEA-based cluster, which contains 96 PowerXCell 8i processors (with theoretical peak performance of 9.83TFlops). We analyze the execution time on a processor and on all 96 processors, with and without utilization of the SPE cores.
