Power distribution management system software deployment

Abstract

Due to the parallel features of hardware devices multi-threading became a trend in applications that require intensive computations. However, it is not always the best [1]. In this ongoing work an overview of real-life Power Distribution Management System (PDMS) is given and its performance in single-threaded and multi-threaded environment is tested. PDMS implements parallelism through sub-division of networks based on their natural features. Each sub-network is run in parallel on separate processor cores using a single thread processing, and with such setup it outperforms the multi-threaded BLAS by the factor of 20. With multi-threading implemented, the performance dreadfully goes down, and processing time increases. Reasons for this are the structure of power distribution network matrices (indefinite and very sparse) and synchronization overhead involved in multi-thread operations.
