PARALLELIZATION OF A SUBSURFACE MASS TRANSPORT NUMERICAL SIMULATION ON PC CLUSTER USING MPI

Abstract

Throughput of a personal computer (PC) cluster, which is a parallel processing system, is approaching a super computer level due to network speed and PC performance improvements. This study evaluated the availability of a PC cluster on a mass transport numerical simulation in subsurface. Method of Characteristic (MOC) was used as a numerical simulation method. The sequential program of MOC was parallelized using Message Passing Interface (MPI), which is a library specification for message-passing in a distributed memory system. The computing speed of eight node PC cluster was six times faster than that of sequential processing. These result in that the parallelization technique using MPI was effective in shortening of the subsurface mass transport simulation by MOC.
