Programming: Many-core Implementation of Numerical 3D Isotropic Acoustic Wave Equation and Analysis of its Performance Portability

Sign up or log in to save this to your schedule and see who's attending!

I discuss how to tune code in a way that a single source file will perform well across many-core architectures such as Xeon Phi and multi-core architectures such as Xeon. I focus on a common Oil&Gas kernel: the 3D isotropic acoustic wave equation. I give performance results for this kernel across multiple architectures and give strategies on how that performance may be achieved from a single source file. I also discuss an alternative propagation model: first-order forms of the wave equation with PML boundary conditions.
