  2. 1. 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

    Abstract : Scientific computing is used frequently in an increasing number of disciplines to accelerate scientific discovery. Many such computing problems involve the numerical solution of partial differential equations (PDE). READ MORE

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

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

    Abstract : 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. Towards Accurate and Resource-Efficient Cache Coherence Prediction

    Author : Jim Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cache coherence protocols; performance evaluation; computer architecture; memory systems; shared memory multiprocessors;

    Abstract : The increasing speed gap between processor microarchitectures and memory technologies can potentially slow down the historical performance growth of computer systems. Parallel applicationns on shared memory multiprocessors that experience cache misses due to communication are extra susceptible to this speed difference. READ MORE
