  1. 1. Multithreaded PDE Solvers on Non-Uniform Memory Architectures

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Markus Nordén; Uppsala universitet.; Uppsala universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; PDE solver; high-performance; NUMA; UMA; OpenMP; MPI; data migration; data replication; thread scheduling; data affinity; Beräkningsvetenskap; Scientific Computing;

    Abstract : A trend in parallel computer architecture is that systems with a large shared memory are becoming more and more popular. A shared memory system can be either a uniform memory architecture (UMA) or a cache coherent non-uniform memory architecture (cc-NUMA). READ MORE

  2. 2. Partition Tolerance and Data Consistency in Structured Overlay Networks

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Shafaat Tallat Mahmood; Tallat M. Shafaat; KTH.; Computer Systems Laboratory.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; SRA - ICT; SRA - Informations- och kommunikationsteknik; Structured overlay networks; distributed Hash tables; network partitions and mergers; size estimation; lookup inconsistencies; distributed key-value stores; linearizability; dynamic reconfiguration; replication.;

    Abstract : Structured overlay networks form a major class of peer-to-peer systems, which are used to build scalable, fault-tolerant and self-managing distributed applications. This thesis presents algorithms for structured overlay networks, on the routing and data level, in the presence of network and node dynamism. READ MORE

  3. 3. Virtual Full Replication for Scalable Distributed Real-Time Databases

    University dissertation from Linköping University

    Author : Gunnar Mathiason; Högskolan i Skövde.; Högskolan i Skövde.; Linköpings universitet.; Linköpings universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology; TEKNIKVETENSKAP Informationsteknik; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi; Teknik; Technology; Scalability; Flexibility; Adaptiveness; Database Replication; Resource Management; Distributed Database; Real-time Database;

    Abstract : A fully replicated distributed real-time database provides high availability and predictable access times, independent of user location, since all the data is available at each node. However, full replication requires that all updates are replicated to every node, resulting in exponential growth of bandwidth and processing demands with the number of nodes and objects added.

  4. 4. Distributed k-ary System: Algorithms for Distributed Hash Tables

    University dissertation from Stockholm : KTH

    Author : Ali Ghodsi; KTH.; SICS.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap; distributed hash tables; structured overlay networks; distributed algorithms; distributed systems; group communication; replication;

    Abstract : This dissertation presents algorithms for data structures called distributed hash tables (DHT) or structured overlay networks, which are used to build scalable self-managing distributed systems. The provided algorithms guarantee lookup consistency in the presence of dynamism: they guarantee consistent lookup results in the presence of nodes joining and leaving. READ MORE

  5. 5. Optimistic Replication with Forward Conflict Resolution in Distributed Real-Time Databases

    University dissertation from Linköping : Linköping university

    Author : Sanny Syberfeldt; Högskolan i Skövde.; Högskolan i Skövde.; Linköpings universitet.; Linköpings universitet.; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY Information technology Computer science Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap Datalogi; Teknik; Technology; Distributed Systems; Real-Time Systems; Databases; Replication; Optimistic Protocol; Conflict Resolution;

    Abstract : In this thesis a replication protocol – PRiDe – is presented, whichsupports optimistic replication in distributed real-time databases withdeterministic detection and forward resolution of transaction conflicts. Theprotocol is designed to emphasize node autonomy, allowing individualapplications to proceed without being affected by distributed operation. READ MORE
