Installation/Configuration Information

NIKHEF operates both a development and an application testbed. On the development testbed, which is dedicated to EDG release testing and software development, we will run the latest tagged development version. Most worker nodes in the development testbed have outbound IPv4 connectivity only.

The NIKHEF application testbed will run the latest "production" release. At this time, that is release 2.1.9. The machines of the application test bed (also known as the NIKHEF production cluster) will be shared by other users (D0-MCC and local jobs). To support the sharing, the application testbed has some non-EDG features such as local user configuration, packages for our own user jobs, and extra management tools (i.e., more LCFG components). The worker nodes in the application test bed have outbound IPv4 connectivity only, no inbound connectivity.
