  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

  5. 4. Hardware–Software Tradeoffs in Shared-Memory Implementations

    Författare :Håkan Zeffer; Erik Hagersten; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

    Sammanfattning : Shared-memory architectures represent a class of parallel computer systems commonly used in the commercial and technical market. While shared-memory servers typically come in a large variety of configurations and sizes, the advance in semiconductor technology have set the trend towards multiple cores per die and multiple threads per core.

  7. 5. Reactive Concurrent Data Structures and Algorithms for Synchronization

    Författare :Phuong Ha; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-blocking; reactive; multi-word atomic primitives; online algorithms; shared memory; concurrent data structures; distributed data structures; randomization; online financial problems; synchronization; spin-locks;

    Sammanfattning : Parallelism plays a significant role in high-performance computing systems, from large clusters of computers to chip-multithreading (CMT) processors. Performance of the parallel systems comes not only from concurrently runningmore processing hardware but also from utilizing the hardware efficiently. LÄS MER
