Summary
The TeamPlay project aims to develop new, formally-motivated, techniques  that will allow execution time, energy usage, security, and other  important non-functional properties of parallel software to be treated  effectively, and as first-class citizens. We will build this into a  toolbox for developing highly parallel software for low-energy systems,  as required by the internet of things, cyber-physical systems etc. The  TeamPlay approach will allow programs to reflect directly on their own  time, energy consumption, security, etc., as well as enabling the  developer to reason about both the functional and the non-functional  properties of their software at the source code level.
Our success  will ensure significant progress on a pressing problem of major  industrial importance: how to effectively manage energy consumption for  parallel systems while maintaining the right balance with other  important software metrics, including time, security etc. The project  brings together leading industrial and academic experts in parallelism, energy modeling/transparency, worst-case execution time  analysis, non-functional property analysis, compilation, security, and  task coordination. Results will be evaluated using industrial use cases  taken from the computer vision, satellites, flying drones, medical and  cybersecurity domains.

Abstract: Modern embedded hard real-time systems feature multiple tasks running on multiple processing cores. Schedulability analysis of such systems is usually performed on an abstract system level with each task being represented as a black box with fixed timing properties. If timing constraints are violated, optimizing the system on a code-level in order to achieve schedulability is a tedious task. To tackle this issue, we propose an extension to the WCET-Aware C Compiler framework WCC. We integrated an optimization framework based on Integer-Linear Programming into the WCC which is able to optimize a multi-core system with multiple tasks running on each core with regards to its schedulability. We evaluate the framework by providing two approaches on a schedulability aware static Scratchpad Memory (SPM) allocation: One based on Integer-Linear Programming (ILP) and one based on a genetic algorithm.
