The CFEL resource in Maxwell are owned by a subgroup of CFEL-DESY and usage of the resources (compute & storage) is usually restricted to that group. If in doubt get in touch with the CFEL DESY admins.
The CFEL resources in Maxwell consist of a few interactive login nodes, batch resources in the cfel partitions and substantial GPFS storage. The compute nodes vary about the CPU-type and availability of GPUs.
Please have a look at Compute Infrastructure page, and the limits applying.
Interactive Login Nodes
To login in to CFEL part of the maxwell cluster you have different:
- ssh max-display.desy.de: will connect you to one of the display nodes. FastX might your better choice. Please have a look at the Access and the Interactive Login.
- ssh max-cfel.desy.de: will connect you to one of the interactive login nodes. It's a load-balanced alias. Use theses nodes to compile, develop or test applications.
- ssh max-cfelg.desy.de: will connect you to one of the interactive login nodes with GPUs. The nodes are equipped with dual K20X GPUs.
- 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!
