Desktop Environment
Desktops and servers in TCM are running Ubuntu 24.04LTS.
Logins
Users can login to TCM devices using their University account (Formerly Raven) crsid and password.
UIS Networks and Remote Access
The RDC and Soulsby datacentre networks are private and firewalled. Inbound connections to TCM desktops and compute servers and not possible from outside, including from wireless networks within the building itself. We have implemented a ssh gateway at which is allowed to make inbound connections. Its address is phy-tcm-gw.phy.cam.ac.uk.
VNC and RDP traffic can be tunnelled through a ssh connection to TCM equipment on these private networks.
Another option would be to use the Physics VPN, but for most users, a ssh connection should be sufficient for their needs.
Hosts
TCM desktops will have hostnames in the form phy-tcm-pc1.phy.private.cam.ac.uk. Compute servers have hostnames phy-tcm-sc1.phy.private.cam.ac.uk. Desktops have IP addresses in the range 10.185.91.128/25, Servers will be in the IP range 10.148.2.10/27.
User data
User home folders are stored on a fileserver (phy-tcm-fs1) and mounted on all TCM computers and servers, ensuring users have access to their data regardless of which PC or server they are connected to. Additionally, there is a shared storage folder mounted in /share where users can collaborate and share data.
Most TCM servers and desktops will also have a folder on local storage /scratch. Generally, this scratch folder will have faster access times than data stored on the fileserver nfs shares.
Printing
Printers should be automatically added to the TCM desktops automatically. The following printers have been configured for TCM:
Location | Printer |
|---|---|
C2.052 | KONICA-MINOLTA-C450 |
C3.014 | KONICA-MINOLTA-C450 |
C3.078 | KONICA-MINOLTA-C450 |
Software
Most software has been installed via ubuntu’s built in apt package manager. This allows us to keep software up to date as the repositories are updated. Software packages that are unavailable from an apt repository have been installed in a shared software folder mounted in /soft . These are generally commercial software packages such as Matlab and Mathematica. They are included in the system path, so you shouldn’t need to go looking for them.
You can request for additional software to be installed; we try to maintain the same software environment for all TCM desktops and servers.
CUDA SDK
To enable the CUDA SDK on machines with nVidia graphics cards, add the following code to the end of your .bashrc file in your home folder:
VARCH=`uname -s`_`uname -m`; export NVARCH
NVCOMPILERS=/soft/nvidia/hpc_sdk; export NVCOMPILERS
MANPATH=$MANPATH:$NVCOMPILERS/$NVARCH/25.9/compilers/man; export MANPATH
PATH=$NVCOMPILERS/$NVARCH/25.9/compilers/bin:$PATH; export PATHHardware
Whenever a desktop PC needs to be moved or relocated, please submit a ticket to IT Services. This helps us keep our records accurate and ensures the devices remain easy to locate for everyone’s convenience.
