1. 1. Static Execution Time Analysis of Parallel Systems

   Författare :Andreas Gustavsson; Björn Lisper; Jan Gustafsson; Andreas Ermedahl; David Broman; Mälardalens högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; WCET analysis; parallel systems; multi-core; multicore; threaded programming language; Computer Science; datavetenskap;

   Sammanfattning : The past trend of increasing processor throughput by increasing the clock frequency and the instruction level parallelism is no longer feasible due to extensive power consumption and heat dissipation. Therefore, the current trend in computer hardware design is to expose explicit parallelism to the software level. LÄS MER

3. 2. Efficient Execution Paradigms for Parallel Heterogeneous Architectures

   Författare :Konstantinos Koukos; Stefanos Kaxiras; Margaret Martonosi; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupled Execution; Performance; Energy; DVFS; Compiler Optimizations; Heterogeneous Coherence; Computer Science; Datavetenskap;

   Sammanfattning : This thesis proposes novel, efficient execution-paradigms for parallel heterogeneous architectures. The end of Dennard scaling is threatening the effectiveness of DVFS in future nodes; therefore, new execution paradigms are required to exploit the non-linear relationship between performance and energy efficiency of memory-bound application-regions.

4. 3. Static Timing Analysis of Parallel Systems Using Abstract Execution

   Författare :Andreas Gustavsson; Björn Lisper; Jan Gustafsson; Andreas Ermedahl; Nan Guan; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; WCET analysis; parallel systems; multi-core; multicore; threaded programming language; Computer Science; datavetenskap;

   Sammanfattning : The Power Wall has stopped the past trend of increasing processor throughput by increasing the clock frequency and the instruction level parallelism.Therefore, the current trend in computer hardware design is to expose explicit parallelism to the software level. 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. Models and Methods for Development of DSP Applications on Manycore Processors

   Författare :Jerker Bengtsson; Bertil Svensson; Shuvra S. Bhattacharyya; Högskolan i Halmstad; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; parallel processing; manycore processors; high-performance digital signal processing; dataflow; concurrent models of computation; parallel code mapping; parallel machine model; dynamic performance analysis; Computer engineering; Datorteknik;

   Sammanfattning : Advanced digital signal processing systems require specialized high-performance embedded computer architectures. The term high-performance translates to large amounts of data and computations per time unit. The term embedded further implies requirements on physical size and power efficiency. LÄS MER
