2. 1. Methods for Creating and Exploiting Data Locality

   Author : Dan Wallin; Erik Hagersten; Sverker Holmgren; David Wood; Uppsala universitet; []
   Keywords : 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;

   Abstract : 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. READ MORE

4. 2. Locality-aware Scheduling and Characterization of Task-based Programs

   Author : Ananya Muddukrishna; Mats Brorsson; Christoph Kessler; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Locality-aware; Task scheduling; OpenMP; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : Modern computer architectures expose an increasing number of parallel features supported by complex memory access and communication structures. Currently used task scheduling techniques perform poorly since they focus solely on balancing computation load across parallel features and remain oblivious to locality properties of support structures.

5. 3. Localising Salafism : Religious Change among Oromo Muslims in Bale, Ethiopia

   Author : Terje Østebø; David Westerlund; David Thurfjell; Anne Kubai; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; Ethiopia; Bale; Islam; Salafism; Religious Change; Locality; Ethnicity; Identity; History of religion; Religionshistoria; religionshistoria; History of Religion;

   Abstract : The political transition in 1991 and the new regime’s policy towards the ethnic and religious diversity in Ethiopia have contributed to increased activities from various Islamic reform movements. Among these, we find the Salafi movement which expanded rapidly throughout the 1990s, particularly in the Oromo-speaking south-eastern parts of the country such as Hararge, Arsi and Bale. READ MORE

6. 4. Software Techniques for Distributed Shared Memory

   Author : Zoran Radovic; Erik Hagersten; Sandhya Dwarkadas; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; synchronization; distributed shared memory; write permission cache; nonuniform communication architecture; node affinity; locality; hardware-software trade-off; profiling; flexibility; trap-based memory architecture; Computer engineering; Datorteknik; Data- och systemvetenskap; Computer Systems Sciences;

   Abstract : In large multiprocessors, the access to shared memory is often nonuniform, and may vary as much as ten times for some distributed shared-memory architectures (DSMs). This dissertation identifies another important nonuniform property of DSM systems: nonuniform communication architecture, NUCA. READ MORE

7. 5. Improving OpenMP Productivity with Data Locality Optimizations and High-resolution Performance Analysis

   Author : Ananya Muddukrishna; Mats Brorsson; Nawal Copty; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; OpenMP; Performance Analysis; Scheduling; Locality Optimizations;

   Abstract : The combination of high-performance parallel programming and multi-core processors is the dominant approach to meet the ever increasing demand for computing performance today. The thesis is centered around OpenMP, a popular parallel programming API standard that enables programmers to quickly get started with writing parallel programs. READ MORE
