User documentation for the PLEIADES cluster at the University of Wuppertal
If you belong to one of the groups participating in PLEIADES, you can get an account by filling out this form. If your group was not involved in PLEIADES, please ask your group leader to contact the support before submitting an account request or consult our HPC.NRW Quick Reference Card.
In case of questions and problems, please use the following email address:
You will receive your initial password from the administrators after your group leader has countersigned the user application. Please change your initial password on any PLEIADES login machine by using the
We recommend to create a password protected ssh-key pair to authenticate on login.
Additionally you can define in your local
Host fugg1 User <USERNAME> Hostname fugg1.pleiades.uni-wuppertal.de IdentityFile ~/.ssh/<KEYNAME>
This way, simply using
ssh fugg1 will log in correctly to the cluster.
More info about ssh keys is available in the corresponding github documentation.
Note: This approach is also more secure, since mis-typing the URL for
uni-wuppertal.decould expose your credentials to a malicious server that is not in our control.
There are two login machine from which the cluster can be operated. They are:
This node can be used to develop and test code. Once this is finished jobs can be submitted to the PLEIADES cluster. This machine runs CentOS 7. You can login on it using your username, which will be provided by us.
Due to massive attacks from all over the world, SSH access is limited to IPs from inside the university’s network (
22.214.171.124/16). In addition, a protection system is used that blocks IP numbers which have been used with several unsuccessful logins. So if you mistype your credentials too often, you will be locked out for a while.
A good practice for using ssh regularly is to setup ssh-keys on your local machine and use
# On your local computer (assuming Linux): # ---------------------------------------- # if you don't have a key, e.g. ~/.ssh/id_ed25519.pub, create a new one # and set a password! ssh-keygen -t ed25519 # copy the ssh key to fugg1 ssh-copy-id USERNAME@fugg1.pleiades.uni-wuppertal.de # Login will now use the ssh key ssh USERNAME@fugg1.pleiades.uni-wuppertal.de
(from your local machine) to enable a key-based login on the frontend.
The login mechanism for whep users is the same as for all other users, except for the login nodes. There are 2 login nodes running CentOS 7 (recommended)
Only whep users can log into higgs and top!!!
