   Sammanfattning : The explosive growth of data in information society poses significant challenges in the timely delivery of information in the context of communication networks. Hence, optimal utilization of scarce network resources is crucial. LÄS MER

4. 3. Three Aspects of Real-Time Multiprocessor Scheduling: Timeliness, Fault Tolerance, Mixed Criticality

   Författare :Risat Pathan; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mixed-Criticality Systems; Fault-Tolerant Scheduling; Fixed Priority; Real-Time Systems; Global Multiprocessor Scheduling; Time Redundancy; Sporadic Tasks;

   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.

5. 4. Scheduling techniques to improve the worst-case execution time of real-time parallel applications on heterogeneous platforms

   Författare :Petros Voudouris; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; parallel applications; global; work-conserving; federated; heterogeneous multiprocessors; response time; Hard real-time systems; unrelated model; DAG; makespan;

   Sammanfattning : The key to providing high performance and energy-efficient execution for hard real-time applications is the time predictable and efficient usage of heterogeneous multiprocessors. However, schedulability analysis of parallel applications executed on unrelated heterogeneous multiprocessors is challenging and has not been investigated adequately by earlier works. LÄS MER

7. 5. Constraint-Based Register Allocation and Instruction Scheduling

   Författare :Roberto Castañeda Lozano; Christian Schulte; Ingo Sander; Mats Carlsson; Laurent Michel; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; constraint programming; combinatorial optimization; register allocation; instruction scheduling; compiler construction; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : Register allocation (mapping variables to processor registers or memory) and instruction scheduling (reordering instructions to improve latency or throughput) are central compiler problems. This dissertation proposes a combinatorial optimization approach to these problems that delivers optimal solutions according to a model, captures trade-offs between conflicting decisions, accommodates processor-specific features, and handles different optimization criteria.
