FFTX for Micromechanical Stress-Strain Analysis

Porting scientific simulations to heterogeneous platforms requires complex algorithmic and optimization strategies to overcome memory and communication bottlenecks. Such operations are inexpressible using traditional libraries (e.g., FFTW for spectral methods) and difficult to optimize by hand for various hardware platforms. In this work, we use our GPU-adapted stress-strain analysis method to show how FFTX, a new API that extends FFTW, can be used to express our algorithm without worrying about code optimization, which is handled by a back-end code generator.
