The hardware structure of the DIFA-OPH computing cluster is summarised in the table below, listing all the compute nodes currently available with their individual hostnames, their specific resources (number of cores and available RAM), and their access policies.

In particular, blue nodes (with names bldNN) are part of the BladeRunner island while the purple nodes (with names mtxNN) are part of the Matrix island.

The nodes associated with the OPH project are open to all users while nodes associated with other individual projects may be subject to access restrictions. Such restrictions are indicated by different colors in the last column of the table, and indicate:

• GREEN: Shared nodes, the access is available for all users
• ORANGE: Shared nodes, with regular weekly reservations for teaching purposes during which the nodes can be accessed only by students of specific DIFA courses for their laboratory activities
• RED: Reserved nodes, the access is restricted to users explicitly authorised by the corresponding project PI for a given period of time
