Webinar: Host courses on Interactive HPC – UCloud

Teachers mark your calendars for April 30!

The DeiC Interactive HPC consortium partners have organised an online webinar about the newly developed concept of UCloud courses.

The webinar is open to researchers from all Danish universities.

If you already know that you would like to use UCloud for a course in the fall of 2025, now is the time to reach out.

In this webinar we will cover:

  1. The newly developed concept of UCloud Courses
  2. The advantages of hosting university courses on UCloud
  3. The teacher application procedure (front office support, financial model and more)
  4. Teacher experiences with hosting courses on UCloud
  5. Q&A 

Details:

Date: April 30 2025
Time: 13:00 – 14:00
Duration: 1 hour

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:
