1. 6. Evaluation of design alternatives for a directory-based cache coherence protocol in shared-memory multiprocessors

   Författare :Håkan Grahn; Blekinge Tekniska Högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : In shared-memory multiprocessors, caches are attached to the processors in order to reduce the memory access latency. To keep the memory consistent, a cache coherence protocol is needed. LÄS MER

3. 7. Towards Accurate and Resource-Efficient Cache Coherence Prediction

   Författare :Jim Nilsson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; cache coherence protocols; performance evaluation; computer architecture; memory systems; shared memory multiprocessors;

   Sammanfattning : The increasing speed gap between processor microarchitectures and memory technologies can potentially slow down the historical performance growth of computer systems. Parallel applicationns on shared memory multiprocessors that experience cache misses due to communication are extra susceptible to this speed difference. LÄS MER

4. 8. Methods for Creating and Exploiting Data Locality

   Författare :Dan Wallin; Erik Hagersten; Sverker Holmgren; David Wood; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; data locality; temporal locality; spatial locality; prefetching; cache; cache behavior; cache coherence; snooping protocols; partial differential equation; shared-memory multiprocessor; chip multiprocessor; simulation; Computer engineering; Datorteknik;

   Sammanfattning : The gap between processor speed and memory latency has led to the use of caches in the memory systems of modern computers. Programs must use the caches efficiently and exploit data locality for maximum performance. LÄS MER

5. 9. Lock-Based Resource Sharing for Real-Time Multiprocessors

   Författare :Sara Afshar; Thomas Nolte; Moris Behnam; Reinder J. Bril; Enrico Bini; Mälardalens högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computer Science; datavetenskap;

   Sammanfattning : Embedded systems are widely used in the industry and are typically resource constrained, i.e., resources such as processors, I/O devices, shared buffers or shared memory might be limited in the system. Hence, techniques that can enable an efficient usage of processor bandwidths in such systems are of great importance. LÄS MER

7. 10. Non-blocking Synchronization: Algorithms and Performance Evaluation

   Författare :Yi Zhang; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The thesis investigates non-blocking synchronization in shared memory systems, in particular in high performance shared memory multiprocessors and real-time shared memory systems. We explore the performance impact of non-blocking synchronization in high performance shared memory multiprocessors and the applicability of non-blocking synchronization in real-time systems. LÄS MER
