21. Tools and Methods for Analysis, Debugging, and Performance Improvement of Equation-Based Models
Sammanfattning : Equation-based object-oriented (EOO) modeling languages such as Modelica provide a convenient, declarative method for describing models of cyber-physical systems. Because of the ease of use of EOO languages, large and complex models can be built with limited effort. LÄS MER
22. Automatic Characterization and Mitigation of Shared-resource Contention in Multi-core Systems
Sammanfattning : Multi-core computers are infamous for being hard to use in time-critical systems due to execution-time variations as an effect of shared resource contention. In this thesis, we study the problem of shared resource contention, which occurs when multiple applications executing on different cores do not have exclusive access to of a shared hardware resource.

23. Shared Memory and OpenMP on Clusters
Sammanfattning : Clusters, i.e., several computers interconnected with acommunication network, provide a cost efficient way to achievehigh performance. Messages are the natural way of communicationin this kind of systems. LÄS MER
24. Modeling the interactions between tasks and the memory system
Sammanfattning : Making computer systems more energy efficient while obtaining the maximum performance possible is key for future developments in engineering, medicine, entertainment, etc. However it has become a difficult task due to the increasing complexity of hardware and software, and their interactions.

25. Data Prefetching Techniques Targeting Single and a Network of Processing Nodes
Sammanfattning : This thesis considers two approaches to the design of high-performance computers. In a single processing node with one processor, performance is degraded when requested data is not found in the cache, because it has to be retrieved from slower memory. LÄS MER
