Component measurable values and services: a technology for the conclusion of resource transactions

The absence of dynamic parameters in the description of software components does not allow the realization of traditional market relations for the Grid, based on transparency in the mechanisms of the allocation of Grid resources for customers and providers. This paper deals with the introduction into the technology of resource distribution of an apparatus of dynamic time and success estimation for the execution of concrete tasks. We discuss extensions to the GCM component model to include dynamically measured properties, the services needed to gather and convey the information, and their implementation using the distributed directory service from the XtreemOS project. With such a strategy it will be possible to realize a full set of traditional market relations and provide a flexible, efficient and transparent resource allocation
