Glue2 support in CREAM

CREAM CE provided with EMI-1 provides some initial support for glue2, that needs to be finalized

1 Target scenario

1.1 CREAM CE in no cluster mode

If the CREAM CE is configured in no cluster mode, all the Glue2 object classes are published by the resource BDII running on the CREAM CE.

The ServiceId is the one specified by the yaim variable COMPUTING_SERVICE_ID (if specified). Otherwise it is ${CE_HOST}_ComputingElement.

1.2 CREAM CE in cluster mode

If instead the CREAM CE is configured in cluster mode:

• The resource BDII running on the CREAM CE publishes just the Endpoint and the AccessPolicy objectclasses
• All the other objectclasses are published by the resource BDII running on the gLite-CLUSTER node
