The XFEL partitions serve for operation and simulations for the XFEL accelerator at DESY. Not to be confused with the European XFEL!° Talk to the M admins or XFEL team if you believe you should have access but don't.
For details about the setup of these partitions please have a look at Compute Infrastructure page, and the limits applying.
Partitions
The XFEL resources are "divided" into three partitions:
- The xfel-op partition. It's a highest priority partition. Jobs in this partition will immediately cancel any jobs in the all, xfel-sim or xfel-guest partition using the same nodes!
- The xfel-sim partition. It's a high priority partition. Jobs in this partition will immediately cancel any jobs in the all or xfel-guest partition using the same nodes!
- The xfel-guest partition. It's a regular priority partition combining all XFEL and PETRA4 resources. Jobs in this partition will terminate jobs in the all partition (like on any other partition). Jobs in the xfel-guest partition will be terminated by any jobs in the xfel-op, xfel-sim or petra4 partition using the same nodes.
Interactive Login Nodes
There are no login nodes associated with the XFEL resources in Maxwell.
- ssh max-display.desy.de: will connect you to one of the display nodes. FastX might your better choice. Please have a look at Access and the Interactive Login.
- ssh max-wgs: will connect you to the generic login node.
- Please note: max-display.desy.de is directly accessible from outside. All other login nodes can only be reached by first connecting to bastion.desy.de.
Login nodes are always shared resources sometimes used by a large number of concurrent users. Don't run compute or memory intense jobs on the login nodes, use a batch job instead!
