Small | Local desktops or workstations that are the users entry point to the grid resources. Client nodes with less than 10 users. | Site frontend to it's local cluster of Worker Nodes. No production sites or less than x jobs processed per h. | Site frontend to it's local data storage. No production sites or Storage < x Tb, service available for a few number of VOs and Users. | The site information node gathers the site resource information and publishes it to the outside. Local information system for sites with less than 5 services available in production. | Accounting services collect compute usage records in the local cluster of Worker Nodes, and publishes a summary of those records into an accounting portal. Sites with less than 2 compute elements, less than x jobs processed per h. | Auth. services hold the local policies for users and VO's to access each resource at the site. Sites which supports less than x VOs and x users. | Nodes in the local cluster allocated to accept and run grid jobs. Sites which supports jobs with low cpu/memory load. |
Big | Clients used by many users to access grid resources. Client nodes with more than 10 users. | Production sites with more than x jobs processed per h. | Service used by a great number of users and VOs. Used storage > x Tb. | Big sites in production with more than 5 services available. Global information system publisher. | Production sites with more than 2 compute elements and more than x jobs processed per h. | Sites in production which support more than x VOs in production. | Sites which supports more than x VOs or jobs with high CPU and memory load. |
