Abstract
The MPPM numerical method parallelization by utilizing the OpenMP environment is reported in this paper. The objective of this work is to reduce the MPPM method computation time by exploiting the otherwise idle processors and overall improve the efficiency of the method. The code solving the Rayleigh-Taylor instability model was originally written using Fortran77 and is considerably slow and was rewritten in C language then parallelized using OpenMP directives. The highest obtained speedup value resulting from OpenMP parallelization is found to be 2.3 which is achieved through utilizing 6 threads out of the available 12 threads. The work presents the possible performance improvement and the importance of addressing the sequential nature of the code in order to further enhance its efficiency. � 2006-2017 Asian Research Publishing Network (ARPN).
