1. Three Aspects of Real-Time Multiprocessor Scheduling: Timeliness, Fault Tolerance, Mixed Criticality
Sammanfattning : The design of real-time systems faces two important challenges: incorporating more functions/services on existing hardware to make the system more attractive to the market, and deploying existing software on multiprocessors (e.g., multicore) to utilize moreprocessing power. LÄS MER
2. Techniques to Tighten the Upper Bound on the ExecutionTime of Task-based Parallel Applications
Detta är en avhandling från ; Chalmers tekniska högskola; GothenburgSammanfattning : To use multiprocessors in hard real-time systems, schedulability analysis is needed to provide formally proven guarantees for the timing behavior of the system. Programming models for parallel applications, such as OpenMP, use pragmas to specify parts of the application as parallel tasks, for example, a function or a body of a loop. LÄS MER
3. Predictable Real-Time Applications on Multiprocessor Systems-on-Chip
Detta är en avhandling från Linköping : Linköping University Electronic PressSammanfattning : Being predictable with respect to time is, by definition, a fundamental requirement for any real-time system. Modern multiprocessor systems impose a challenge in this context, due to resource sharing conflicts causing memory transfers to become unpredictable. LÄS MER
4. Exploiting Fine-grain Parallelism in Concurrent Constraint Languages
Detta är en avhandling från Linköping : Linköping University Electronic PressSammanfattning : This dissertation presents the design, implementation, and evaluation of a system that exploits fine-grain implicit parallelism in concurrent constraint programming language. The system is able to outperform a C implementation of an algorithm with complex dependencies without any user annotations. LÄS MER
5. Runtime Management of Multiprocessor Systems for Fault Tolerance, Energy Efficiency and Load Balancing
Detta är en avhandling från ; Chalmers tekniska högskola; GothenburgSammanfattning : Efficiency of modern multiprocessor systems is hurt by unpredictable events: aging causes permanent faults that disable components; application spawnings and terminations taking place at arbitrary times, affect energy proportionality, causing energy waste; load imbalances reduce resource utilization, penalizing performance. This thesis demonstrates how runtime management can mitigate the negative effects of unpredictable events, making decisions guided by a combination of static information known in advance and parameters that only become known at runtime.
