PATUS for Convenient High-Performance Stencils: Evaluation in Earthquake Simulations
SESSION: Autotuning and Search-Based Optimization
EVENT TYPE: Papers
TIME: 11:30AM - 12:00PM
SESSION CHAIR: Francois Bodin
AUTHOR(S):Matthias Christen, Olaf Schenk, Yifeng Cui
Patus is a code generation and auto-tuning framework for the class of stencil computations targeted at modern multi- and many-core processors. The goals of the framework are productivity, portability, and achieving a high performance on the target platform. Its stencil specification DSL allows the programmer to express the computation in a concise way independently of hardware architecture-specific details. Thus, it increases the programmer productivity by disburdening her or him of low level programming model issues. We illustrate the impact of the stencil code generation in seismic applications. The challenges in computational seismology are to harness these stencil-code generation techniques for wave propagation problems, for which weak and strong scaling are important. We evaluate the performance showing two examples: (1) focusing on a scalable discretization of the wave equation, and (2) testing complex simulation types of the AWP-ODC code to enable petascale 3D earthquake calculations and aims on aggressive parallel efficiency.
