  1. 1. Speculative Attacks on Nordic Exchange Rates, 1971-1992

    Författare :Mats-Ola Forsman; Göteborgs universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Balance of Payments Crisis; Nordic; Exchange rates; Speculative Attacks;

    Sammanfattning : This paper analyzes the relationship between economic fundamentals and balance-of-payments crises for the three Nordic countries, Norway, Sweden, and Finland, during 1971-1992. To identify periods of balance-of-payments crisis a method first introduced by Eichengreen, Rose, and Wyplosz (1996) was used. LÄS MER

  3. 2. Rethinking Speculative Execution from a Security Perspective

    Författare :Christos Sakalis; Magnus Själander; Alexandra Jimborean; Stefanos Kaxiras; Josep Torrellas; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; computer architecture; speculative execution; processor; security; out-of-order execution; side-channel; microarchitectural replay; microarchitecture; Delay-on-Miss; Ghosts; Delay-on-Squash; Computer Science; Datavetenskap;

    Sammanfattning : Speculative out-of-order execution is one of the fundamental building blocks of modern, high-performance processors. To maximize the utilization of the system's resources, hardware and software security checks in the speculative domain can be temporarily ignored, without affecting the correctness of the application, as long as no architectural changes are made before transitioning to the non-speculative domain.

  4. 3. Securing the Memory Hierarchy from Speculative Side-Channel Attack

    Författare :Christos Sakalis; Magnus Själander; Sven Karlsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : Modern high-performance CPUs depend on speculative out-of-order execution in order to offer high performance while also remaining energy efficient. However, with the introduction of Meltdown and Spectre in the beginning of 2018, speculative execution has been under attack. LÄS MER

  5. 4. Finding and Exploiting Memory-Level-Parallelism in Constrained Speculative Architectures

    Författare :Kim-Anh Tran; Alexandra Jimborean; Stefanos Kaxiras; Louis-Noël Pouchet; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Memory-level-parallelism; Energy-efficiency; Performance; Compiler; Instruction Scheduling; SW HW Co-Design; Computer Science; Datavetenskap;

    Sammanfattning : One of the main performance bottlenecks of processors today is the discrepancy between processor and memory speed, known as the memory wall. While the processor executes instructions at a high pace, the memory is too slow to provide data in a timely manner. LÄS MER

  7. 5. Markov Regime Switching in Economic Time Series

    Författare :Ulf Erlandsson; Nationalekonomiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Nationalekonomi; ekonometri; ekonomisk teori; ekonomiska system; ekonomisk politik; forecasting; Markov switching; exchange rates; interest rates; business cycle; economic policy; economic systems; economic theory; econometrics; Economics; currency crisis;

    Sammanfattning : This dissertation studies statistical properties and applications of the Markov switching models for economic time series in five separate papers. The two main statistical themes are (i) the task of choosing the number of states to use in the model, and (ii) inference on time-varying transition probabilities. LÄS MER
