The PETRA4 partition serves for simulations and design studies for PETRA4. Talk to the M admins or Ilya Agapov if you believe you should have access but don't.
Please note: access to the petra4 partition implies access to the xfel-guest partition. See Maxwell for XFELfor details!
For details about the setup of these partitions please have a look at Compute Infrastructure page, and the limits applying.
Interactive Login Nodes
There are no login nodes associated with the PETRA4 resources in Maxwell. Having access to the petra4 partition does NOT allow to use max-display, you need one of the regular maxwell resources for this.
- ssh max-display.desy.de: will connect you to one of the display nodes but only if you have a regular maxwell resource. 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!
