Mr Philippe Canal (FERMILAB)
We will review the architecture and implementation of the accounting service for the Open Science Grid. Gratia's main goal is to provide the OSG stakeholders with a reliable and accurate set of views of the usage of resources across the OSG. We will review the status of deployment of Gratia across the OSG and its upcoming development. We will also discuss some aspects of current OSG usage as illustrated by information provided by Gratia.
