Aspen - A Domain Specific Language for Performance Modeling
SESSION: Performance Modeling
EVENT TYPE: Papers
TIME: 11:30AM - 12:00PM
SESSION CHAIR: Dimitris Nikolopoulos
AUTHOR(S):Kyle L. Spafford, Jeffrey S. Vetter
We present a new approach to analytical performance modeling using Aspen, a domain specific language. Aspen (Abstract Scalable Performance Engineering Notation) fills an important gap in existing performance modeling techniques and is designed to enable rapid exploration of new algorithms and architectures. It includes a formal specification of an application’s performance behavior and an abstract machine model. We provide an overview of Aspen’s features and demonstrate how it can be used to express a performance model for a three dimensional Fast Fourier Transform. We then demonstrate the composability and modularity of Aspen by importing and reusing the FFT model in a molecular dynamics model. We have also created a number of tools that allow scientists to balance application and system factors quickly and accurately.
