    • Improving the performance of the in-band byte stream file transfer XMPP extension 

      Orlin, Karsten (Master thesis; Mastergradsoppgave, 2009-09-24)
      In looking at the XMPP protocol as an alternative to the ordinary way of transferring files within a health network setting, namely e-mail, performance and security are important factors to consider. For security reasons we preferred to use in-band over out-of-band file transfer. The tradeoff is that this method puts a higher strain on the XMPP server and is significantly slower than its counterpart, ...

    • Skynet: A distributed, autonomous filesystem 

      Aas, Svein Ove (Master thesis; Mastergradsoppgave, 2010-05)
      Existing networked filesystems are usually either client/server - allowing storage only on one node - hard to use, or both. The advanced ones also like to use their own on-disk format, complicating migration both ways. Skynet attempts to remedy this. It is a distributed filesystem with master/slave redundancy that is easy to use, relatively safe for your data and can be easily converted to/from ...
    • A context-aware mobile bus application 

      Hansen, Christer Andre (Master thesis; Mastergradsoppgave, 2010-05-18)

    • WallMon : Interactive distributed monitoring of process-level resource usage on display and compute clusters 

      Nilsen, Arild (Master thesis; Mastergradsoppgave, 2011-11)
      To achieve low overhead, traditional cluster monitoring systems sample data at low frequencies and with coarse granularity. However, interactive monitoring requires frequent (up to 60 Hz) sampling of fine-grained data and visualization tools that can explore and display data in near real-time. This makes traditional cluster monitoring systems unsuited for interactive monitoring of distributed cluster ...
