Jump to navigationJump to search


The only way to access the CRAY XT5m (frontend/login nodes) from outside HWW net is through ssh. Information on how to set up ssh can be found on our webserver at Secure Shell (ssh).


There is only one frontend/login node for users available:

  • hwwxt5.hww.de

The frontend node is intended as single point of access to the entire cluster. Here you can set your environment, move your data, edit and compile your programs and create batch scripts. Interactive usage like run your program which leads to a high load is NOT allowed on the frontend/login node.

The 112 compute nodes for running parallel jobs are only available through the Batch system !
