1. 1. Managing Service Levels in Grid Computing Systems : Quota Policy and Computational Market Approaches

   Författare :Thomas Sandholm; Lennart Johnsson; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Grid Market; Computational Grid; Service Level Management; QoS; HPC; Grid Middleware; Computer science; Datavetenskap;

   Sammanfattning : We study techniques to enforce and provision differentiated service levels in Computational Grid systems. The Grid offers simplified provisioning of peak-capacity for applications with computational requirements beyond local machines and clusters, by sharing resources across organizational boundaries.

3. 2. Computational methods for microfluidics

   Författare :Ludvig af Klinteberg; Anna-Karin Tornberg; Peter Hansbo; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : This thesis is concerned with computational methods for fluid flows on the microscale, also known as microfluidics. This is motivated by current research in biological physics and miniaturization technology, where there is a need to understand complex flows involving microscale structures. Numerical simulations are an important tool for doing this. LÄS MER
