Implementation of an XML-based user interface with applications in ice sheet modeling

The scientific domain presents unique challenges to software developers. This thesis describes the application of design patterns to the problem of dynamically changing interfaces to scientific application software (GLIMMER, which performs ice sheet modeling). In its present form, GLIMMER uses a text configuration file to define model behavior, set parameters, and structure model input/output (I/O). The creation of the configuration file presents a significant problem to users due to its format and complexity. GLIMMER is still under development, and the number of changes to configuration parameters, parameter types, and parameter dependencies makes devel-opment of any single interface of use only for a short term. The application of design patterns described here resulted in an interface specification tool that then generates multiple versions of a user interface usable across a wide variety of configuration pa-rameter types, values, and dependencies. The resulting products have leveraged de-sign patterns and solved problems associated with design pattern usage not found in the specialized software engineering literature

Using Heat and Ceilometer to create an elastic OpenStack grid

Grid computing is a term for connecting computing resources together to solve large computational problems. Computational grids are used for a lot of computations within the high energy physics domain, where the amount of computing power required for some tasks is vastly more than a local computer can provide. This thesis investigates if cloud technology can be utilized to make an elastic computational grid, in order to get access to more resources that would otherwise be idle. Functional requirements were defined for creating a prototype capable of providing a virtualized environment that scales the amount of virtual machines up and down automatically based on the load on the system. A prototype was created to take advantage of the technology provided by cloud, and the prototype tested to see how it fulfills the functional requirements. Although one of the functional requirements was not achieved, the test results demonstrate that the technology has promising potential, but further work and testing needs to be done.Masteroppgave i informatikkINF39
