A Checkpoint of research on the implementation of geophysical stencils on multicore platforms
Fabrice Dupros, C. Hillairet · 2019
Summary He production of reliable three-dimensional images of the subsurface remains a major challenge in the oil and gas industry and strongly relies on the efficient exploitation of supercomputers. However, as each vendor is working on next-generation technologies, the landscape of architectures that may be available leads to increasing concerns regarding real applicative performance. Whatever the design of these systems will be (heterogeneity, high core counts or depth of the memory hierarchy), it is admitted that co-design approaches will play a major role to ensure that oil and gas applications will be in best position to adopt the next breakthroughs. In this paper, after a review of recent contributions for the optimization of geophysical stencils, we discuss key feature from Arm hardware that may influence standard implementations.
