We rely on the CS LDAP server for user authentication. In order to use the cluster, you need to have a CS account. If you do not have one, please contact the techstaff@cs.uchicago.edu.
Someone sent you but no CNETID provided, you can go to whoami.uchiago.edu to get the CNETID.
The uchicago email is cnetid@uchicago.edu. So you can also parse the CNETID from the email address.
Similarly, send the ticket to the cs techstaff.

sudo rmmod nvidia
# Then, reload them if desired:
sudo modprobe nvidia
sudo modprobe nvidia_modeset
sudo modprobe nvidia_drm
sudo modprobe nvidia_uvm
Check the short name of your ip address, it alwasys safe to use the full name.
For example, a001.cs.uchicago.edu and a001.ds.cs.uchicago.edu are the different names but share the same short name a001. So when you
ssh a001The behavior is undefined. It may connect to a001.cs.uchicago.edu or a001.ds.cs.uchicago.edu. Normally cs, since c is before d in the alphabet.
ssh a001.ds.uchicago.edu
Same for the configuration file. Always use the full name.
ssh cluster-mgmt.ds.uchicago.edu
sudo salt '*' pkg.install nvidia-cuda-toolkit
It will install the package on all nodes, including the login nodes. Which is not preferred. We can create a list of computation nodes and install the package on them via saltstack.
sudo salt '*' pkg.upgrade
