Implementação da computação massivamente paralela na simulação Monte Carlo em transporte de radiação ionizante

Abstract

The code used is PENELOPE (Penetration and ENErgy LOss of Positrons and Electrons), which is a computer code based on MMC, created with the objective of assisting in the simulations of transport systems of neutral and charged particles using deterministic and stochastic methods. Among the problems that this area faces today, one of the main ones is the waiting time until the end of the simulation, which in certain cases can last days, thus making it impossible for the researcher to use his personal computer to carry out the simulations, and also the difficulty of configuring a text file that requires specific tabs for the simulation to occur. The Penelope Parallelization Software (SOPPE) is a solution based on the use of massively parallel architecture with the use of the GPU (Graphics Processing Units), which resulted in incredible speed gains of up to 145 times. The configuration of these simulations was also improved due to the development of a user-friendly interface, specifically designed for this purpose. The simulations were carried out using only the researcher's personal computer, together with a video card for parallelization, contributing significantly to the advancement of studies in this area.
