As hardware components in computer systems have become more unreliable due to the technology scaling, hardware errors, resulting from soft errors (e.g., transient faults) and permanent errors (e.g., faults due to aging mechanisms etc.), have become unavoidable. It is, therefore, crucial for system designers to exploit effective hardware and software techniques to improve the dependability. This research proposal aims to achieve dependability improvement by adopting offline and online software techniques in case the underlying hardware components are unreliable. To bridge the gap between hardware and software techniques for achieving a high degree of reliability, the project will explore proper hardware reliability and software resilience modeling to guide system software and application software generation (through compiler) towards reliability improvement. The techniques are reliability-guided compilation, reliability-aware task scheduling and mapping/remapping, as well as dynamic software composition. Both offline and online techniques are required and will be explored in the project in order to find effective means of how to adapt them to each other.

This proposal makes contributions to the following columns of the SPP 1500:

• Dependable Embedded Software
• Operation, Observation and Adaptation

We will pursue the following objectives within this proposal:

Objective 1: Developing Reliability-Driven Compilation and System Software Techniques for Dependable Code Generation and Execution.
Objective 2: Developing an Adaptive Run-Time System for Dependable Code Executions.
Objective 3: Modeling Reliability and Resilience.

Both offline and online techniques are required and it is a main objective to find means of how to jointly design offline techniques and run-time adaptiveness. Tight integration of system software, compilation techniques, and adaptive run-time system is a key to enable a highly-dependable software system for embedded systems.

6. TSP: Thermal Safe Power
   Short Description: Thermal Safe Power (TSP) is a power budget concept that provides safe power constraint values as a function of the number of simultaneously operating cores in many-core systems. It avoids the performance losses caused by using a single and constant value as a power constraint. This software tool implements the algorithms to compute the TSP for the given multi-/many-core processor configuration and thermal constraints.
7. MatEx: Efficient Transient and Peak Temperature Computation for Compact Thermal Models
   Short Description: MatEx implements a method for computing the transient temperature peaks (resulting from resource management decisions changing the power consumption in a many-core system) in just a few milliseconds, which is suited for run-time usage. Moreover, MatEx can also be used to efficiently compute all transient temperatures for any given time resolution without accuracy losses.
