  1. 1. Graceful Degradation of Adaptive Multiprocessor Systems on a Chip

    Författare :Stavros Tzilis; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; design space exploration; runtime management; graceful degradation; system optimization; Defect and fault tolerance;

    Sammanfattning : This thesis explores the potential for using existing flexibility in order to allow Multiprocessor Systems on a Chip to function in the presence of permanent faults and to prolong their lifetime. Technology scaling in accordancewith Moore’s law brings up reliability challenges and forces the use of potentially unreliable hardware components. LÄS MER

  3. 2. Runtime Management of Multiprocessor Systems for Fault Tolerance, Energy Efficiency and Load Balancing

    Författare :Stavros Tzilis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Tolerance; Algorithms; Runtime Management; Multiprocessors; Performance; Adaptive Systems; Load Balancing; Energy Efficiency;

    Sammanfattning : 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.
