Developing Distributed Computing Solutions Combining Grid Computing and Public Computing

M.Sc. Thesis by Jakob Gregor Pedersen & Christian Ulrik Søttrup


As modern research relies more and more on computers, computer cycles are becoming a scarce resource for research projects, as well as a large part of the cost. Some projects try to solve this problem by relying on computer resources donated by the public. The drawback to this approach is that the public resources are stochastic in nature. It is therefore not possible to predict when a study will finish.

Our goal is to create a resource that will supply a scientific research project with reliable compute power using computers donated by the public. To this end we will use BOINC, a newly created open platform that tries to lower the cost of computational resources for research by using donated cycles. We propose to build a bridge between this platform and Grid computing to solve the problem of reliability. Grid computing is a platform that seeks to solve the problem of scarcity. It does this by allowing researchers around the world to buy, sell, or share computational resources. We show that using a mix of these resources it should be possible to supply an inexpensive resource with guarantees on the quality of service. We also propose a design for integrating this resource into the Grid, thus making it easier to use.
