  1. 6. Advances Towards Data-Race-Free Cache Coherence Through Data Classification

    Författare :Mahdad Davari; Kaxiras Stefanos; Erik Hagersten; Alberto Ros; Manuel Eugenio Acacio Sánchez; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shared Memory Architectures; Multicore; Memory Hierarchy; Cache Coherence; Data Classification;

    Sammanfattning : Providing a consistent view of the shared memory based on precise and well-defined semantics—memory consistency model—has been an enabling factor in the widespread acceptance and commercial success of shared-memory architectures. Moreover, cache coherence protocols have been employed by the hardware to remove from the programmers the burden of dealing with the memory inconsistency that emerges in the presence of the private caches.

  4. 8. Efficient Implementation of Concurrent Data Structures on Multi-core and Many-core Architectures

    Författare :Bapi Chatterjee; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synchronization Primitives; Lock-free Binary search tree; Lock-free; Concurrent Data Structures;

    Sammanfattning : Synchronization of concurrent threads is the central problem in order to design efficient concurrent data-structures. The compute systems widely available in market are increasingly becoming heterogeneous involving multi-core Central Processing Units (CPUs) and many-core Graphics Processing Units (GPUs). LÄS MER

  5. 9. Multithreaded PDE Solvers on Non-Uniform Memory Architectures

    Författare :Markus Nordén; Michael Thuné; Sverker Holmgren; Xing Cai; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PDE solver; high-performance; NUMA; UMA; OpenMP; MPI; data migration; data replication; thread scheduling; data affinity; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : 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). LÄS MER

  7. 10. Towards Accurate and Resource-Efficient Cache Coherence Prediction

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

    Sammanfattning : 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. LÄS MER
