      Murphy, Michael J. (Master thesis; Mastergradsoppgave, 2017-05-15)
      It is still strangely difficult to backup and synchronize data. Cloud computing solves the problem by centralizing everything and letting someone else handle the backups. But what about situations with low connectivity or sensitive data? For this, software developers have an interesting distributed, decentralized, and partition-tolerant data storage system right at their fingertips: distributed ...

    • Space-Bounded Async Scheduling. A UPCxx extension 

      Verma, Nishant (Master thesis; Mastergradsoppgave, 2017-05-15)
      It is estimated that computers and mobile devices use more than 2% of the total energy consumed. That means a lot of energy is going in powering our cpu,display and gpu. In this paper we are trying to optimize the power consumed by cpu in partitioned global address space environment. Recent research suggests that there is scope in improving cpu power usage by having a better scheduler. Simhadri ...

    • EC3 - Edge Command-Control-Communication System for Arctic Observatories 

      Michalik, Lukasz Sergiusz (Master thesis; Mastergradsoppgave, 2017-05-13)
      This paper presents a prototype of a system for automated observations of flora and fauna in the Arctic. Currently applied methods of observation depend mostly on systems (usually consisting of a camera unit, a motion detection sensor and a memory card) that are left unattended in remote locations during extended periods of data gathering. The main problem with such approach is that no remote control ...

    • AutoMon. Automatic monitoring and problem detection for distributed systems 

      Wikstad, Magnus (Master thesis; Mastergradsoppgave, 2016-05-15)
      When working with distributed systems, detecting faults can be a difficult task, as abnormalities isn't necessarily immediately evident by warnings or system crashes. This is especially true with subtle faults, such as variations in performance of a running program, it is not necessarily its own fault, but could rather be from a different source, somewhere in the cluster, using a lot of resources ...

    • A framework for building scalable web applications for high-resolution cluster-based display walls
