1. 16. Optimizing Performance in Highly Utilized Multicores with Intelligent Prefetching

   Författare :Muneeb Khan; Erik Hagersten; David Black-Schaffer; Bengt Jonsson; Per Stenström; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Performance; Optimization; Prefetching; multicore; memory hierarchy; Computer Science; Datavetenskap;

   Sammanfattning : Modern processors apply sophisticated techniques, such as deep cache hierarchies and hardware prefetching, to increase performance. Such complex hardware structures have helped improve performance in general, however, their full potential is not realized as software often utilizes the memory hierarchy inefficiently. LÄS MER

3. 17. Adaptive Resource Management Techniques for High Performance Multi-Core Architectures

   Författare :Nadja Holtryd; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cache Partitioning; Bandwidth Partitioning; Resource Management; Performance Isolation; Multi-Core Architectures; Prefetch Throttling;

   Sammanfattning : Reducing the average memory access time is crucial for improving the performance of applications executing on multi-core architectures. With workload consolidation this becomes increasingly challenging due to shared resource contention. Previous works has proposed techniques for partitioning of shared resources (e.g. LÄS MER

5. 19. Parallelizing the Method of Conjugate Gradients for Shared Memory Architectures

   Författare :Henrik Löf; Jarmo Rantakokko; Erik Hagersten; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap; Scientific Computing;

   Sammanfattning : Solving Partial Differential Equations (PDEs) is an important problem in many fields of science and engineering. For most real-world problems modeled by PDEs, we can only approximate the solution using numerical methods. Many of these numerical methods result in very large systems of linear equations. LÄS MER

7. 20. Adaptive Microarchitectural Optimizations to Improve Performance and Security of Multi-Core Architectures

   Författare :Nadja Holtryd; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-Core Architectures; Bandwidth Partitioning; Prefetch Throttling; Cache Partitioning; Microarchitectural Optimizations; Side-channel Attacks;

   Sammanfattning : With the current technological barriers, microarchitectural optimizations are increasingly important to ensure performance scalability of computing systems. The shift to multi-core architectures increases the demands on the memory system, and amplifies the role of microarchitectural optimizations in performance improvement. LÄS MER
