Parallel Performance of Numerical Algorithms on Multi-core System Using OpenMP

The current microprocessors are concentrating on the multiprocessor or multi-core system architecture. The parallel algorithms are recently focusing on multi-core system to take full utilization of multiple processors available in the system. The design of parallel algorithm and performance measurement is the major issue on today's multi-core environment. Numerical problems arise in almost every branch of science which requires fast solution .System of linear equations has applications in fusion energy, structural engineering, ocean modeling and method of moment formulation. In this paper parallel algorithms for computing the solution of system of linear equations and approximate value of pi are presented. The parallel performance of numerical algorithms on multi-core system have been analyzed and presented. The experimental results reveal that the performances of parallel algorithms are better than sequential. We implemented the parallel algorithms using multithreading features of OpenMP.
