1. 1. Schemes to Improve the Efficiency of Hardware Transactional Memory Systems

   Författare :Mridha Mohammad Waliullah; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transactional memory; parallel programming; chip-multiprocessor; multiprocessor;

   Sammanfattning : In todays ubiquitous multiprocessor environment parallel programming becomesan important tool to reap the maximum gain. But the traditional lock-based parallelprogramming model is not attracting average programmers as the level of expertiseneeded is very high. LÄS MER

3. 2. Insights on non-partitioned fixed-priority preemptive scheduling

   Författare :Björn Andersson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; real-time systems; non-partitioned method; fixed-priority scheduling; static-priority scheduling; multiprocessor; shared-memory multiprocessor; real-time scheduling; scheduling anomalies; global scheduling; Dhall s effect;

   Sammanfattning : .... LÄS MER

4. 3. Predictable Real-Time Applications on Multiprocessor Systems-on-Chip

   Författare :Jakob Rosén; Zebo Peng; Petru Eles; Thomas Nolte; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Embedded Systems; Real-Time Systems; Predictability; Multiprocessor Systems; Computer science; Datavetenskap;

   Sammanfattning : 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

5. 4. Techniques to Tighten the Upper Bound on the ExecutionTime of Task-based Parallel Applications

   Författare :Petros Voudouris; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Scheduling; Multiprocessor; WCET; Uniform; Hard; multicore; Related; DAG; Real-Time; Dynamic; Unrelated; Makespan; Homogeneous; Parallel; Identical;

   Sammanfattning : 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

7. 5. Exploiting Fine-grain Parallelism in Concurrent Constraint Languages

   Författare :Johan Montelius; RISE; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Implicit parallelism; Concurrent Constraint Programming; Cache performance; Logic programming; Abstract machine; Parallel execution; Scheduling; Multiprocessor; Shared memory;

   Sammanfattning : 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
