  1. 1. Formal Verification of Peripheral Memory Isolation

    Författare :Jonas Haglund; Roberto Guanciale; Mads Dam; Gligor Virgil; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; formal verification; interactive theorem proving; direct memory access; memory isolation; input output; formell verifiering; interaktiv datorassisterad beviskonstruktion; direkt minnesåtkomst; minnesisolering; indata utdata; Datalogi; Computer Science;

    Sammanfattning : In many contexts, computers run both critical and untrusted software,necessitating the need for isolating critical software from untrusted software.These computers contain CPUs, memory and peripherals. LÄS MER

  3. 2. Hiding and Reducing Memory Latency : Energy-Efficient Pipeline and Memory System Techniques

    Författare :Andreas Sembrant; David Black-Schaffer; Erik Hagersten; David A. Wood; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Computer Science; Datavetenskap;

    Sammanfattning : Memory accesses in modern processors are both far slower and vastly more energy-expensive than the actual computations. To improve performance, processors spend a significant amount of energy and resources trying to hide and reduce the memory latency. LÄS MER

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cloud computing; Next-generation data centers; Resource disaggregation; Total cost of ownership; Last level cache; Direct cache access; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : The cloud is evolving due to additional demands introduced by new technological advancements and the wide movement toward digitalization. Moreover, next-generation Data Centers (DCs) and clouds are expected (and need) to become cheaper, more efficient, and capable of offering more predictable services. LÄS MER

  7. 5. Accelerating Distributed Storage in Heterogeneous Settings

    Författare :Waleed Reda; Dejan Kostic; Peter Van Roy; Marco Chiesa; Adam Morrison; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Distributed storage; File systems; Hardware offload; Persistent memory; Distribuerad lagring; Dilsystem; Maskinvaruavlastning; Beständigt minne; Computer Science; Datalogi;

    Sammanfattning : Heterogeneity in cloud environments is a fact of life—from workload skews and network path changes, to the diversity of server hardware components, these are all factors that impact the performance of distributed storage. In this dissertation, we identify that heterogeneity can in fact be one of the primary causes of service degradation for storage systems. LÄS MER
