Approximate Systems (Dagstuhl Seminar 21302)

Authors: Eva Darulova, Babak Falsafi, Andreas Gerstlauer, and Phillip Stanley-Marbell

Published in: Dagstuhl Reports, Volume 11, Issue 6 (2021)

Abstract
This report summarizes the presentations and discussion sessions at the Dagstuhl Seminar 21302 "Approximate Systems" that took place during July 25 - 30, 2021. Due to COVID, the seminar was held in a hybrid fashion, with around 1/3 of the attendees on-site and the remaining ones online. The seminar discussed advances and open challenges in applying approximate computing techniques across the stack and across different application domains, and we hope that this report can provide a useful resource also for other researchers.

07041 Working Group – Towards Interfaces for Integrated Performance and Power Analysis and Simulation

Authors: Chris Bleakley, Tom Clerckx, Harald Devos, Matthias Grumer, Alex Janek, Ulrich Kremer, Christian W. Probst, Phillip Stanley-Marbell, Christian Steger, Vasanth Venkatachalam, and Manuel Wendt

Published in: Dagstuhl Seminar Proceedings, Volume 7041, Power-aware Computing Systems (2007)

Abstract
In the design and optimization of power-aware computing systems, it is often desired to estimate power consumption at various levels of abstraction, e.g., at the transistor, gate, RTL, behavioral or transaction levels. Tools for power estimation at these different levels of abstraction require specialized expertise, e.g., understanding of device physics for circuit-level power estimation, and as such are necessarily developed by different research communities. In the optimization of complete platforms however, it is desired to be able to obtain aggregate power and performance estimates for the different components of a system, and this requires the ability to model the system at a mixture of levels of abstraction. One approach to enabling such cross-abstraction modeling, is to define a mechanism for interchange of data between tools at different layers of abstraction, for both static analysis and simulation-based studies. This document presents preliminary discussions on the requirements of such an interface.

The Sunflower Tool Suite --- Hardware and Software Research Platforms for Energy-Constrained and Failure-Prone Systems

Authors: Phillip Stanley-Marbell

Published in: Dagstuhl Seminar Proceedings, Volume 7041, Power-aware Computing Systems (2007)

Abstract
Research in any field requires tools that enable modeling system characteristics of interest. Such tools, whether analytic, simulative, or hardware-based, must enable the accurate evaluation of relevant aspects of a system that may influence its perceived utility. In computing systems research, software tools (notably, simulators) provide low-cost, flexible, and low turn-around time facilities for investigations, but abstract away many hardware details, often resulting in a loss in accuracy of modeling. Hardware implementations provide the ultimate proofs of concept, but require hardware design expertise, are usually expensive and inflexible, and are not always designed to expose all possible system parameters to researchers. They are also rarely the subject of active evolution over time as research platforms in their own right, as software tools are. The Sunflower tool suite is a suite of hardware platforms and simulation tools, intended to address these concerns. It comprises a full-system (embedded microarchitecture, networking, power, battery, device failure and analog signal modeling) simulator, a miniature energy-scavenging hardware platform, and a handheld computing device (under development). The suite is intended to provide a set of complementary platforms for research in micro- and system-architectures for embedded systems, with emphases on energy-efficiency, fault-tolerance, and ecological impact of deployed hardware.
