Parallelization of a Monte Carlo Simulation for a Space Cosmic Particles Detector

摘要

Work in progress in the design of a parallel simulation of a multipurpose cosmic rays detector is presented. The detector is part of an experiment whose main goal is to study the spectrum and composition of charged cosmic rays with unprecedent sensibility. A sequential version of the simulator based on Monte Carlo method is currently available, but it is ineffective for the study of large samples of moderately high charged particles. Parallelism seems to be the most suitable approach to increase its performance. Driven by different reasons we have decided to take the sequential code as a starting point instead of producing a parallel version from scratch. In this work we present the preliminaxy computational results that we have obtained for our first prototype of the parallel MPI master-slave simulator on a PC cluster platform.
