  2. 1. Live VM Migration : Principles and Performance

    Author : Petter Svärd; Erik Elmroth; Eric Jul; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Live Migration; Virtualization; business data processing; administrativ databehandling;

    Abstract : Virtualization is a key technology for cloud computing as it allows several operating system instances to run on the same machine, enhances resource manageability and enables flexible definition of billing units. Virtualization works by adding a software layer, a hypervisor, on top of the hardware platform. READ MORE

  4. 2. Performance, Availability, and Scalability in Open Networking Platforms for Internet Services

    Author : Voravit Tanyingyong; Peter Sjödin; Markus Hidell; Raimo Kantola; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network architecture and design; Network communications; Performance; Availability; Scalability; Internet of Things IoT ; Nätverksarkitektur och design; nätverkskommunikation; prestanda; tillgänglighet; skalbarhet; sakernas internet IoT ; Informations- och kommunikationsteknik; Information and Communication Technology;

    Abstract : Advancement in technologies brings about new demands and services. In parallel, modern commodity off-the-shelf (COTS) hardware has become very capable yet affordable. It is often used in combination with Free/Libre and Open Source Software (FLOSS) to build open networking platforms, which offer alternatives to commercial network devices. READ MORE

  5. 3. Automation of Load Haul Dump machines : comparative performance analysis and maintenance modeling

    Author : Anna Gustafson; Sunniva Haugen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Drift och underhållsteknik; Operation and Maintenance Engineering;

    Abstract : The Load Haul Dump (LHD) machine and its operating environment create a complex system. Mine productivity depends on the operation of the LHDs and on the mining environment, including fragmentation, size of boulders, navigation techniques etc. Traditional navigation techniques require a lot of infrastructure to accommodate automatic operation.

  6. 4. Performance and Implementation Complexity in Multiprocessor Operating System Kernels

    Author : Simon Kågström; Blekinge Tekniska Högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Operativsystem; multiprocessorer; implementationskomplexitet;

    Abstract : The increasing use of multiprocessor computers require operating system adaptations to take advantage of the computing power. However, porting an operating system kernel to run on a multiprocessor can be very difficult because of a large code base, concurrency issues when dealing with multiple threads of execution, and limited tool support for development.
