1. 1. Performance Modeling of Multi-core Systems : Caches and Locks

   Författare :Xiaoyue Pan; Bengt Jonsson; David Whalley; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; performance modeling; performance analysis; multi-core; cache; lock;

   Sammanfattning : Performance is an important aspect of computer systems since it directly affects user experience. One way to analyze and predict performance is via performance modeling. In recent years, multi-core systems have made processors more powerful while keeping power consumption relatively low. LÄS MER

3. 2. Concurrent Algorithms and Data Structures for Many-Core Processors

   Författare :Daniel Cederman; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; composition; sorting; graphics processors; lock-free; software transactional memory; parallel; load balancing; multi-core;

   Sammanfattning : The convergence of highly parallel many-core graphics processors with conventional multi-core processorsis becoming a reality.To allow algorithms and data structures to scale efficiently on these new platforms,several important factors needs to be considered. LÄS MER

4. 3. Timing Predictability in Future Multi-Core Avionics Systems

   Författare :Andreas Löfwenmark; Simin Nadjm-Tehrani; Risat Pathan; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Timing Predictability; WCET; WCRT; Fault Tolerance; Safety Critical; Avionics;

   Sammanfattning : With more functionality added to safety-critical avionics systems, new platforms are required to offer the computational capacity needed. Multi-core platforms offer a potential that is now being explored, but they pose significant challenges with respect to predictability due to shared resources (such as memory) being accessed from several cores in parallel.
