From remote servers, you can use software licensed by the university on your own devices in the same way as on university workstations. You can use the remote desktops that you have access to for your studies or work. The services described here are for students and staff of the University of Oulu.

When working outside of the university, you can access AVD and Linux remote desktops without a VPN connection. For other remote desktop services, you will need either FortiClient or OpenVPN on your computer. In addition, OpenVPN requires a personal openvpn profile to work. There are separate instructions for setting these up:

Remote Desktops and Applications Available

AVD Remote Desktop

Windows Servers:

jalava1.univ.yo.oulu.fi / jalava2.univ.yo.oulu.fi

Linux Computing Servers:

The University of Oulu offers Linux computing servers for staff and students. The graphical desktop environment of Linux computing servers can be accessed through https://lehmus.oulu.fi portal. The desktop can be activated via the Lehmus VDI app. Select the length of the session (max. 168 hours / 7 days) and the resources that you need. Please don’t reserve too many resources because it may affect your next session. After you have created the session, you can connect to it by clicking “Connect to session” or you can use a local VNC Viewer and follow the instructions.
You can log in to ongoing sessions via the “My Interactive Sessions” tab. The Lehmus portal is available without a VPN connection.

The Kataja VDI found in the portal, allows you to use the desktop of the older Kataja6, Kataja7 and Kataja8 servers.

Available applications

Applications on computing servers are accessible either directly from the path or, in most cases, through the Lmod environment. Below you will find examples of using the Lmod environment

1. List of available apps and app versions
$ module avail matlab

----------------------- /sw/apps/modulefiles/Core ------------------------
matlab/R2019a matlab/R2020a matlab/R2021b
matlab/R2019b matlab/R2020b matlab/R2022b

------------------------- /sw/rhel8/modulefiles --------------------------
matlab/R2022a matlab/R2023b (D)
matlab/R2023a matlabruntime/95

Where:
D: Default Module

If the avail list is too long consider trying:

"module --default avail" or "ml -d av" to just list the default modules.
"module overview" or "ml ov" to display the number of modules for each
name.

Use "module spider" to find all possible modules and extensions.
Use "module keyword key1 key2 ..." to search for all possible modules
matching any of the "keys".

OR

$ module avail matlab

----------------------- /sw/apps/modulefiles/Core ------------------------
matlab/R2019a matlab/R2020a matlab/R2021b
matlab/R2019b matlab/R2020b matlab/R2022b

------------------------- /sw/rhel8/modulefiles --------------------------
matlab/R2022a matlab/R2023b (D)
matlab/R2023a matlabruntime/95

Where:
D: Default Module

If the avail list is too long consider trying:

"module --default avail" or "ml -d av" to just list the default modules.
"module overview" or "ml ov" to display the number of modules for each
name.

Use "module spider" to find all possible modules and extensions.
Use "module keyword key1 key2 ..." to search for all possible modules
matching any of the "keys".
2. Deploying the application
$ module load matlab/R2023b
$ matlab
MATLAB is selecting SOFTWARE OPENGL rendering.

Network Directories

The following network drives are available on computing servers:

/homedirXX/<username>

User’s linux home directory (drive H:)

/homedirXX/<username>

User’s Windows home directory (Drive K:)

/study//

The workspace used in the course. The teacher can apply for more space without charge for students from ICT services.

/study/<year//<username>

The student’s course-specific work directory.

/research/<groupdirectory>

A directory created for research groups. Research groups can apply these from ICT services.

The above directories have the snapshot feature enabled, which allows you to easily recover deleted files from the hidden .snapshot directory. Below is an example of restoring a file from an hourly backup on weekdays. In the example, the deleted palautettava_testi.sh is recovered in the home directory. (NB. Palautettava is Finnish and means ”to be recovered”.)

$ pwd
/homedirXX/kkkani
$ ls
testi.sh
$ cd .snapshot
$ ls

$ cd ad-homedirXX-hourly-2023-10-09-09-00
$ ls
testi.sh palautettava_testi.sh
$ cp palautettava_testi.sh $HOME/palautettava_testi.sh
$ cd $ HOME
$ ls
testi.sh palautettava_testi.sh

NB. You won’t find this functionality on local directories, e. g. /tmp or /var/tmp.
For more information about using the environment, please contact ict@oulu.fi. Through the service address, you can also leave a request to implement application installations on servers.
