  2. 6. Profiling Methods for Memory Centric Software Performance Analysis

    Author : David Eklöv; Erik Hagersten; Lieven Eeckhout; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Computer Science;

    Abstract : To reduce latency and increase bandwidth to memory, modern microprocessors are often designed with deep memory hierarchies including several levels of caches. For such microprocessors, both the latency and the bandwidth to off-chip memory are typically about two orders of magnitude worse than the latency and bandwidth to the fastest on-chip cache.

  4. 7. Cache memory design trade-offs for current and emerging workloads

    Author : Martin Karlsson; Erik Hagersten; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer Systems; Datorteknik;

    Abstract : The memory system is the key to performance in contemporary computer systems. When designing a new memory system, architectural decisions are often arbitrated based on their expected performance effect. It is therefore very important to make performance estimates based on workloads that accurately reflect the future use of the system. READ MORE

  5. 8. Memory System Design for Chip-Multiprocessors

    Author : Martin Karlsson; Erik Hagersten; Mikko Lipasti; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : The continued decrease in transistor size and the increasing delay of wires relative to transistor switching speeds led to the development of chip multiprocessors (CMPs). The introduction of CMPs presents new challenges and trade-offs to computer architects. READ MORE

  6. 9. Optimizing Performance in Highly Utilized Multicores with Intelligent Prefetching

    Author : Muneeb Khan; Erik Hagersten; David Black-Schaffer; Bengt Jonsson; Per Stenström; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Performance; Optimization; Prefetching; multicore; memory hierarchy; Computer Science; Datavetenskap;

    Abstract : Modern processors apply sophisticated techniques, such as deep cache hierarchies and hardware prefetching, to increase performance. Such complex hardware structures have helped improve performance in general, however, their full potential is not realized as software often utilizes the memory hierarchy inefficiently. READ MORE

  7. 10. Iterative and Adaptive PDE Solvers for Shared Memory Architectures

    Author : Henrik Löf; Jarmo Rantakokko; Sverker Holmgren; Erik Hagersten; Mark Bull; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; partial differential equations; iterative methods; finite elements; conjugate gradients; adaptive mesh refinement; multigrid; cc-NUMA; distributed shared memory; OpenMP; page migration; TLB shoot-down; bandwidth minimization; reverse Cuthill-McKee; migrate-on-next-touch; affinity; temporal locality; chip multiprocessors; CMP; Beräkningsvetenskap; Scientific Computing;

    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
