A model of non functional properties for grid resources
(Springer, 2009) Buján Carballal, David; Corcho-García, Óscar; Díaz Labrador, Josuka
So far, Grid information providers basically give functional values about resources, although some of them also provide aggregated information. Therefore, existing Grid information models essentially represent this syntactic information and also propose different taxonomies of resources. Hence, Grid information consumers commonly use functional properties to select resources in order to send jobs to a Grid. There are some approaches that try to use isolated techniques to take into consideration some QoS properties, like performance. In this paper, we propose a unified model for representing Grid resources and their non functional properties, adding semantics to Grid information systems. On one hand, this model is an ontology-based model developed to integrate existing approaches of Grid information models and non functional properties representations in general. But on the other hand, our model also proposes a measuring system - currently in development - for some non functional properties like reliability, availability and performance. Here we only present an overview about how to represent and measure reliability information of resources in Grids. This example is used to illustrate our work in progress.
