Implementação paralela em um ambiente de múltiplas GPUs de um modelo 3D do sistema imune inato

Abstract

The development of computer systems that simulate the behavior of tissues or even whole organs is an extremely complex task. One of the many obstacles related to the development of such systems is the huge computational resources needed to execute the simulations. For this reason, the use of strategies and methods that employ parallel computing are essential. This work focuses on the spatial-temporal simulation of some human innate immune system (HIS) cells and molecules in a three-dimensional section of tissue. Aiming to reduce the time required to perform the simulation, multiple graphics processing units (GPUs) were used in a cluster environment. Despite of high communication cost imposed by the use of multiple GPUs, the approaches and techniques used in this work to implement parallel versions of the simulator proved to be very effective in their purpose of reducing the simulation time.
