Where to install

Modules need to be installed in the internal as well as external clusters.

Internal clusters

• install on ribosome

DMZ cluster

Since the DMZ cluster has xeon as well as opteron systems, perl modules have to be installed on one machine of each type.

• install on lactose (opteron)
• install on amylose (xeon)
