User accounts for the GPU cluster must be created by someone with administrative-level access to the servers. Currently (March 2020) Cao Peng is designated Admin.
The standard process is:
- Request account from Admin
- Receive ID and password via email or WhatsApp.
Contents
Initial setup
- SSH login and change your password upon first login, using the command
passwd
.
After this, the user will have a folder on /home/[userID]
that can't be accessed by non-admins.
Deactivate your anaconda environment (optional)
The Anaconda base environment may be activated by default when you first log in. To prevent this automatic activation type: conda config --set auto_activate_base false
Guide to using MATLAB commandline
Just use matlab
on the commandline to start the interactive console.
See the MATLAB documentation for more options.
currently not installed systemwide, see HKU MATLAB for installation notes
Guide to using VNC
- set a
vnpcpasswd
- check if the folder
~/.vnc
exists, if not try runningvncserver
- copy 2 config files into ~/.Xresources and ~/.vnc/xstartup
- running
vncserver -name <yourname> :4
will give you a VNC at port 5904. The port formula is 5900+N. - check your existing vncs with
vncserver -list
. Terminate them withvncserver -kill <N>
where <N> is the integer. - In case the desktop is blank upon login, replace the last line in ~/.vnc/xstartup with
dbus-launch xfce-session
. This seems to be a bug related to xfce and/or anaconda. If that fails tryconda uninstall dbus
.
