Performance analysis of acoustic seismic wave modeling on GPUs with OpenMP
Abstract
O software Mamute implementa uma solução numérica para a equação da onda, problema com alto custo computacional na sísmica. Este algoritmo rodava originalmente apenas em CPU com multithreading, e sua adaptação em GPU via OpenMP será comentada neste trabalho. Ademais, comparou-se as performances dos compiladores GCC e Clang, com este último sendo sempre superior em GPU.References
