Servers

The Department of Meteorology and Geophysics has access to the following computing resources:

  • Teaching Server SRVX1
  • Development Server Aurora
  • Services Server SRVX8
  • Computing Cluster JET
  • Vienna Scientific Cluster VSC

Available Work Environments

Locations:

Note: Please take a look at the training course @VSC. There might be a beginners course about Linux or Clusters or Python! It is highly recommended to use these existing courses to get up to speed. Most of these are available as pdfs right away, but still taking the course is the prefered way.

Containers

Containerization is done via singularity/apptainer. There is a repository on gitlab that hosts container definitions and related files. Some of these containers are build and available via the gitlab container registry.

Example

To use a container, you can pull it from the GitLab container registry and run it with singularity/apptainer. Here is a basic example:

Bash

# Make sure apptainer / singularity is available
apptainer -v

# Pull the container image from the GitLab container registry
apptainer pull imagemagick.sif oras://registry.phaidra.org/imgw/singularity/imagemagick:latest
# Execute the container:
./imagemagick.sif 
[OUTSIDE] run: singularity run-help imagemagick.sif
[INSIDE] Welcome inside an IMGW container!
[IMGW-alma8.magick]~/tmp$

Look for more public containers on gitlab container registry.

Integration

Some of these containers are integrated into the module system of the IMGW servers. e.g. module load imagemagick

example loading imagemagick

# on IMGW server
module load imagemagick
** INFO: This is a containerized version of Imagemagick.
** INFO: The following tools are available: 
**        animate compare composite conjure convert display identify import mogrify montage stream

# ok seems to work:
convert test.jpg test.png
If you are interested in more details look into the module file.

Need another application that is not available but too complicated to be served natively on a multi user environment?
