Challenges of WCET Analysis in COTS Multi-core due to Different Levels of Abstraction

The continuous demand of producing low cost multi-core hardware for safety critical hard real time applications has driven attempts of using Commercial Off The Shelf (COTS) components. Prior to the industrial deployment, Worst Case Execution Time (WCET) of these applications must be estimated on underlying hardware. However, even simple COTS components exhibit unpredictability at very low level...

Fault-Tolerant Execution on COTS Multi-core Processors with Hardware Transactional Memory Support

The demand for fault-tolerant execution on high performance computer systems increases due to higher fault rates resulting from smaller structure sizes. As an alternative to hardware-based lockstep solutions, software-based fault-tolerance mechanisms can increase the reliability of multi-core commercial-of-the-shelf (COTS) CPUs while being cheaper and more flexible. This paper proposes a softwa...

Deterministic Measurement of Reliability and Performance Using Explicit Colored Petri Net in Business Process Execution Language and Eflow

Today there are many techniques for web service compositions. Evaluation of quality parameters has great impact on evaluation of final product. BPEL is one of those techniques that several researches have been done on its evaluation. However, there are few researches on evaluation of QoS in eflow. This research tries to evaluate performance and reliability of eflow and BPEL through mapping them...

Predictable SoC architecture based on COTS multi-core

With the increasing complexity of real-time embedded applications and the availability of Commercial-Off-TheShelf (COTS) multi-cores, time-predictable execution on these platforms has become a necessity. However, there are several challenges to achieving this predictability, primarily arising due to hardware resources shared between the cores (memory controllers, caches and shared interconnect)...

Hardware error detection using AN-Codes

Due to the continuously decreasing feature sizes and the increasing complexity of integrated circuits, commercial off-the-shelf (COTS) hardware is becoming less and less reliable. However, dedicated reliable hardware is expensive and usually slower than commodity hardware. Thus, economic pressure will most likely result in the usage of unreliable COTS hardware in safety-critical systems. The us...
