Access

The only way to access the NEC Nehalem Cluster (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).

Usage

There are 2 frontend/login nodes for academic users available:

  • cl3fr1.hww.de
  • cl3fr2.hww.de

The frontend nodes are 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 nodes.

The 700 compute nodes:

  • n010501-n143302

for running parallel jobs are only available through the Batch system !
