1. 1. Software Techniques for Distributed Shared Memory

   Författare :Zoran Radovic; Erik Hagersten; Sandhya Dwarkadas; Uppsala universitet; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER

3. 2. Distributed cognition in home environments : The prospective memory and cognitive practices of older adults

   Författare :Mattias Forsblad (Kristiansson); Nils Dahlbäck; Corinna Kruse; Fredrik Stjernberg; Oskar Lindwall; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; HUMANIORA; HUMANITIES; Distributed cognition; intelligent use of space; cognitive aging;

   Sammanfattning : In this thesis I explore how older people make use of, and interact with, their physical environment in home and near-by settings to manage cognitive situations, specifically prospective memory situations. Older adults have in past research been shown to perform better on prospective memory in real-life settings than what findings in laboratory-like settings predict. LÄS MER

4. 3. Topics in Distributed Algorithms: On Wireless Networks, Distributed Storage and Streaming

   Författare :Thomas Petig; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Message Passing; Wireless Networks; Time Division Multiple Access; Shared Memory; Fault-Tolerance; Streaming; NP-Hardness; Distributed Algorithm; Optimisation; TDMA;

   Sammanfattning : Distributed algorithms are executed on a set of computational instances. Werefer to these instances as nodes. Nodes are runningconcurrently and are independent from each other. Furthermore, they have their own instructions and information. LÄS MER

5. 4. Towards Low-Complexity Scalable Shared-Memory Architectures

   Författare :Håkan Zeffer; Erik Hagersten; John Carter; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; shared memory; distributed shared memory; hardware-software trade-off; software coherence; coherence profiling; remote access cache; chip multiprocessor; simultaneous multi threading; simulation; workload characterization; statistical cache model; Computer engineering; Datorteknik;

   Sammanfattning : Plentiful research has addressed low-complexity software-based shared-memory systems since the idea was first introduced more than two decades ago. However, software-coherent systems have not been very successful in the commercial marketplace. We believe there are two main reasons for this: lack of performance and/or lack of binary compatibility. LÄS MER

7. 5. Accelerating Distributed Storage in Heterogeneous Settings

   Författare :Waleed Reda; Dejan Kostic; Peter Van Roy; Marco Chiesa; Adam Morrison; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed storage; File systems; Hardware offload; Persistent memory; Distribuerad lagring; Dilsystem; Maskinvaruavlastning; Beständigt minne; Computer Science; Datalogi;

   Sammanfattning : Heterogeneity in cloud environments is a fact of life—from workload skews and network path changes, to the diversity of server hardware components, these are all factors that impact the performance of distributed storage. In this dissertation, we identify that heterogeneity can in fact be one of the primary causes of service degradation for storage systems. LÄS MER
