2012 Proceedings of the 49th Annual Design Automation Conference on - DAC '12  
This paper discusses the Angstrom processor, which is designed to support a new Self-aware Computing (SEEC) model.  ...  In SEEC, applications explicitly state goals, while other systems components provide actions that the SEEC runtime system can use to meet those goals.  ...  Angstrom is a proposed 1000-core, massively manycore processor that supports self-aware computing by exposing a wide array of actions (in the form of different hardware configurations) and observations  ...

A generalized software framework for accurate and efficient management of performance goals

Henry Hoffmann, Martina Maggio, Marco D. Santambrogio, Alberto Leva, Anant Agarwal
2013 2013 Proceedings of the International Conference on Embedded Software (EMSOFT)  
In this paper, we propose PTRADE, a novel performance management framework that is general with respect to the components it manages.  ...  PTRADE's generality is demonstrated through the management of performance goals for a variety of benchmarks on two different Linux/x86 systems and a simulated 128-core system, each with different components  ...  PTRADE is an example of a self-aware computing system [17, 16] that understands high-level user goals and automatically adjusts behavior to meet those goals optimally.  ...
