With single thread performance starting to plateau, HW architects have turned to chip level multiprocessing (CMP) to increase processing power. All major microprocessor companies are aggressively shipping multi-core products in the mainstream computing market. Moore's law will largely be used to increase HW thread-level parallelism through higher core counts in a CMP environment. CMPs bring new challenges into the design of the software system stack. In this tutorial, we talk about the shift to multi-core processors and the programming implications. In particular, we focus on transactional programming. Transactions have emerged as a promising alternative to lock-based synchronization that eliminates many of the problems associated with lock-based synchronization. We discuss the design of both hardware and software transactional memory and quantify the tradeoffs between the different design points. We show how to extend the Java and C languages with transactional constructs, and how to integrate transactions with compiler optimizations and the language runtime (e.g., memory manager and garbage collection).
Translating time expression into absolute time points or durations is a challenge for natural languages processing such as text mining and text understanding in general. We present a constraint logic language CLP(Time...

This paper presents a new tuning method based on model parameters identified in closed-loop. For classical controllers such as PI(D) controllers a large number of simple tuning methods for various application areas exist. However, when it comes to designing a generalised predictive controller (GPC) four parameters have to be specified. To choose those parameters is not a trivial task since they are not directly related to control or regulation performance. The presented tuning method exploits model-parameters to select suitable controller parameters. Additionally, a Rhinehart filter is incorporated in the design to decrease the impact of noise, therefore, a fifth parameter has to be optimised. The proposed method has been tested in simulation and on a real system.
