Dynamic Runtime Environments for Grid Computing

• In a grid computing context the execution of jobs on remote machines of collaborating institutes often requires the provisioning of more than mere CPU time. Besides libraries and utilities distributed with the operating system in question, further software may be required by the jobs and in such cases need to be installed prior to the job's execution. In grid computing this problem is aggravated by decreased personal contacts among collaborators. Currently, Virtual Organisations of existing production grids typically agree on a set of runtime environments that participating sites install manually. The challenge is to automate this process, thus easing the burden of the site's maintainers and allowing grid-wide software updates with immediate eject. This paper presents an RDF based schema for the description of runtime environments and the implementation of a service for their automated and dynamic installation.
