UCloud Undervisning Workshop

Udvikling af din egen UCloud-kursusapp med en nyudviklet skabelonbaseret tilgang

Deltag i en praktisk workshop, hvor vi guider dig gennem alle trin i udviklingen af en UCloud-kursusapp ved hjælp af vores nyudviklede skabelonbaserede tilgang. Konceptet går ud på at have en dedikeret app på UCloud til dit universitetskursus, som studerende kan bruge f.eks. i øvelses-/labsessioner og/eller derhjemme. En introduktion til tilgangen findes i denne webinaroptagelse.

I denne workshop lærer du at:

  • Oversætte din kursusstruktur til en struktur, der er kompatibel med en UCloud-kursusapp.
  • Opsætte kursusudviklingsmiljøet, hvilket indebærer at klone GitHub-repositoriet og køre et kursus-setup-script.
  • Tilpasse de medfølgende skabeloner for at bygge en UCloud-kursusapp, der inkluderer alle nødvendige komponenter – softwareafhængigheder, scripts, datasæt og mere.
  • Teste kurset på din egen computer under udviklingen for at sikre, at alt fungerer korrekt. Vi ser også, hvordan den færdige kursusapp ser ud, når den er lagt på UCloud.

Git/GitHub og Docker er essentielle værktøjer i udviklingen af UCloud-kursusapps. I workshoppen giver vi korte introduktioner til begge værktøjer, primært rettet mod deltagere uden forudgående erfaring. Deltagerne kan med fordel gennemgå introduktionsmateriale til Git og Docker på forhånd, men det er ikke et krav.

Dato: 11. juni 2025

Tidspunkt: 12:30–14:30 (CET)

Sted: Online, via Zoom (link følger)

Målgruppe: Forskere og undervisere fra alle afdelinger på alle danske universiteter

Teknisk niveau: Grundlæggende til avanceret

No More Waiting for Resources

Streamline your workflow when using DeiC Interactive HPC

Have you ever experienced delays due to high demand for computing resources on UCloud (DeiC Interactive HPC)? The key to faster access and reducing system strain is efficient resource management.

Over-requesting can lead to unnecessary waiting because DeiC Interactive HPC operates by allocating resources to users as the requested resources become available, without the use of priority queues. Consequently, if you select a large machine for a relatively small task, you will need to wait for other tasks requested for these larger but fewer machines to finish, leading to prolonged waiting.

“Users with little or no experience in assessing the amounts of resources needed have a tendency to request more than they actually need.  This causes unnecessary queues and frustration for other users. However, we also see experienced users choosing the large machines simply out of habit instead of starting small, and subsequently migrate to a larger machine only when necessary.”

Jes Elgin, Cloud Engineer at DeiC Interactive HPC

To avoid delays, users need to accurately assess and request only the necessary resources for their task. Starting with conservative estimates can expedite access and improve overall system efficiency.

“Choosing small will always give you a head start as there are more small machines, and you can always upgrade to a large machine if you need it. You don’t have to start over, and you won’t lose any data.”

Jes Elgin, Cloud Engineer at DeiC Interactive HPC

**TIP!** Did you know that the likelihood of obtaining a machine right away is higher the less resources you request?

So, choose your machine based on a qualified estimate of resources needed. If unsure start small and seek advice from experienced colleagues or the DeiC Front Office.

New way to use SSH for accessing apps on Interactive HPC 

One minute! 

That’s how long it took to set up the new SSH access to DeiC Interactive HPC applications. 

If SSH is of interest to you, you probably know that DeiC Interactive HPC applications have recently experienced limitations in providing a reliable and scalable solution for accessing their services using Secure Shell Protocol (SSH).

The challenges were attributed to a limited number of available IP addresses from the common pool on their platform, along with the implementation of a more scalable solution. The latter proved to be burdensome, as acquiring multiple new IP addresses would not provide the scalability required.
However, DeiC Interactive HPC has launched a new solution for Secure Shell Protocol access that eliminates the need for multiple IP addresses. This new solution is based on ports which are much more scalable. Therefore, users can now access DeiC Interactive HPC applications using SSH with ease.

To access this new solution, users only need to create a private/public key or use an existing one and add the public key to their account at Interactive HPC. Then select one of the supported applications and follow the documentation. Supported applications include AlmaLinux Xfce vJun2023, Rsync v3.2.7, Terminal Ubuntu vJun2023, Terminal Debian vJun2023, Terminal AlmaLinux vJun2023, Ubuntu Xfce vJun2023, and JupyterLab v4.0.2. Soon to be added to this list are RStudio and all the Coder applications.

With this new solution in place, users can now enjoy pure command-line bliss without any limitations or challenges:
