1. 1. Effective cooperative scheduling of task-parallel applications on multiprogrammed parallel architectures

   Författare :Georgios Varisteas; Mats Brorsson; Avi Mendelson; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multicore; parallel; scheduler; workload; runtime; task; adaptive; resource management; load balancing; work-stealing; Computer Science; Datalogi;

   Sammanfattning : Emerging architecture designs include tens of processing cores on a single chip die; it is believed that the number of cores will reach the hundreds in not so many years from now. However, most common parallel workloads cannot fully utilize such systems. LÄS MER

3. 2. Cooperative user- and system-level scheduling of task-centric parallel programs

   Författare :Georgios Varisteas; Mats Brorsson; Karl-Filip Faxén; Timothy Roscoe; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel; workload; runtime; task; adaptive; resource management; load balancing; work-stealing; SRA - ICT; SRA - Informations- och kommunikationsteknik;

   Sammanfattning : Emerging architecture designs include tens of processing cores on a single chip die; it is believed that the number of cores will reach the hundreds in not so many years from now. However, most common workloads cannot expose fluctuating parallelism, insufficient to utilize such systems. LÄS MER

4. 3. Improving Performance and Quality-of-Service through the Task-Parallel Model​ : Optimizations and Future Directions for OpenMP

   Författare :Artur Podobas; Mats Brorsson; Georgi Gaydadjiev; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Task Parallel; OpenMP; Scheduling; OmpSs; multicore; manycore; Datalogi; Computer Science;

   Sammanfattning : With the failure of Dennard's scaling, which stated that shrinking transistors will be more power-efficient, computer hardware has today become very divergent. Initially the change only concerned the number of processor on a chip (multicores), but has today further escalated into complex heterogeneous system with non-intuitive properties -- properties that can improve performance and power consumption but also strain the programmer expected to develop on them.

5. 4. Advances in Task-Based Parallel Programming for Distributed Memory Architectures

   Författare :Afshin Zafari; Elisabeth Larsson; George Bosilca; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel programming; task-based programming; distributed memory system; scientific computing; hierarchical data; hierarchical tasks;

   Sammanfattning : It has become common knowledge that parallel programming is needed for scientific applications, particularly for running large scale simulations. Different programming models are introduced for simplifying parallel programming, while enabling an application to use the full computational capacity of the hardware. LÄS MER

7. 5. 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
