Description
The heterogeneity of resources in computational grids, such as the Canadian GridX1,
makes application deployment a difficult task. Virtual machine environments promise
to simplify this task by homogenizing the execution environment across the grid. One
such environment, Xen, has been demonstrated to be a highly performing virtual
machine monitor. In this work, we evaluate the applicability of Xen to scientific
computational grids. We verify the functionality and performance of Xen, focusing on
the execution of software relevant to the LHC community. A variety of production
deployment strategies are developed and tested. In particular, we compare the
execution of job-specific and generic VM images on grids of conventional Linux
clusters as well as virtual clusters.
