In this paper, we discuss the porting strategy and the achieved performance of Petrobras production code that implements Kirchhoff prestack time and depth seismic migration algorithms on a cluster of 64 GPUs and 256 CPU cores. The time migration of a

We discuss the performance of Petrobras production Kirchhoff prestack seismic migration on a cluster of 64 GPUs and 256 CPU cores. Porting and optimization of the application hot spot (98.2% of a single CPU core execution time) to a single GPU reduce

This paper describes performance results obtained by porting production seismic imaging software to a set of novel processor architectures, with particular emphasis on a cluster of GPUs. Introduction Seismic processing algorithms are constantly evolv

We describe the computational characteristics of the Kirchhoff prestack seismic migration currently used in daily production runs at Petrobras and its port to novel architectures. Fully developed in house, this portable and fault tolerant application

We describe a method to perform two-pass 3-D Kirchho prestack time migration whose com- putation time is nearly the square-root of that required for the one-pass algorithm. To better understand the conditions and restrictions associated with the appl

Este trabalho visa avaliar a viabilidade do uso de paralelismo no processamento sísmico. Para isto foi escolhida uma aplicação representativa (migração sísmica), resolvida por um algoritmo comumente empregado em produção (migração w-x). Sua
