  1. 11. Efficient methods for application performance analysis

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

    Sammanfattning : To reduce latency and increase bandwidth to memory, modern microprocessors are designed with deep memory hierarchies including several levels of caches. For such microprocessors, the service time for fetching data from off-chip memory is about two orders of magnitude longer than fetching data from the level-one cache. LÄS MER

  3. 12. Understanding Multicore Performance : Efficient Memory System Modeling and Simulation

    Författare :Andreas Sandberg; Erik Hagersten; David Black-Schaffer; David A. Wood; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Architecture; Simulation; Modeling; Sampling; Caches; Memory Systems; gem5; Parallel Simulation; Virtualization; Sampling; Multicore; Datavetenskap; Computer Science;

    Sammanfattning : To increase performance, modern processors employ complex techniques such as out-of-order pipelines and deep cache hierarchies. While the increasing complexity has paid off in performance, it has become harder to accurately predict the effects of hardware/software optimizations in such systems. LÄS MER

  4. 13. High Performance Hybrid Memory Systems with 3D-stacked DRAM

    Författare :Evangelos Vasilakis; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DRAM caches; Data migration; 3D-stacked DRAM; Hybrid memory systems;

    Sammanfattning : The bandwidth of traditional DRAM is pin limited and so does not scale well with the increasing demand of data intensive workloads. 3D-stacked DRAM can alleviate this problem providing substantially higher bandwidth to a processor chip. LÄS MER

  5. 14. On the Performance Analysis of Large Scale, Dynamic, Distributed and Parallel Systems

    Författare :John Ardelius; Seif Haridi; Supriya Krishnamurthy; Mark Jelasity; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Performance analysis distributed systems; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Evaluating the performance of large distributed applications is an important and non-trivial task. With the onset of Internet wide applications there is an increasing need to quantify reliability, dependability and performance of these systems, both as a guide in system design as well as a means to understand the fundamental properties of large-scale distributed systems.

  7. 15. On the Role of Performance Interference in Consolidated Environments

    Författare :Navaneeth Rameshan; Vladimir Vlassov; Manish Parashar; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Performance; Interference; Virtualization; Elastic Scaling; Utilization; Datalogi; Computer Science;

    Sammanfattning : With the advent of resource shared environments such as the Cloud, virtualization has become the de facto standard for server consolidation. While consolidation improves utilization, it causes performance-interference between Virtual Machines (VMs) from contention in shared resources such as CPU, Last Level Cache (LLC) and memory bandwidth.
