Interactive HPC Research Supercomputing Teaching UCloud Use case

UCloud Provides Student Access to Advanced NLP in Teaching 

In the Master’s programme in Cognitive Science at Aarhus University, UCloud plays a central role in teaching Natural Language Processing (NLP). For instructor and PhD student Mina Almasi, the platform is essential in enabling students to work hands-on with complex models – regardless of the limitations of their own computers.

From Theory to Hands-On Learning 

In a white classroom in Nobelparken, Mina stands in front of 15 students. On the screen behind her, lines of Python code appear in neat, symmetrical rows as she explains which code libraries the students need to access.

In her teaching, she uses the Coder Python application in UCloud because the course is based on Python programming. But the choice of platform is not just about software – it is about giving students the opportunity to translate theory into practice.

According to Mina, NLP teaching previously tended to remain at a more theoretical level, due to limited access to both models and the computing power needed to test theories in practice – especially when it came to large language models. With UCloud, students can now work directly with language models (LLMs) and make use of powerful GPUs and CPUs. This allows them to test theories themselves and experiment hands-on with the tools they are learning about.

“We still teach the theory, but now we can also have students use the tools in practice. They can code on their own and gain insight into how a large language model works by working directly with it through UCloud,” she explains.

A Standardised Setup that Democratises the Classroom 

Another advantage of using UCloud in NLP teaching is that the platform ensures equal access for all students, regardless of the computer they own.

“There is a kind of democratisation of the classroom, because you don’t need the latest computer. You can use a five-year-old machine to run very heavy tasks that the newest tools in Natural Language Processing require,” she explains.

At the same time, the standardised setup makes teaching more seamless. All students work with the same standard configuration in UCloud, so any issues that arise are the same for everyone. This creates a shared sense of problem-solving, as challenges can be addressed collectively rather than handled individually by students on their own. As Mina puts it:

“Instead of stopping the lesson to solve individual problems, the problems become collective and an opportunity for learning for everyone. If we have a software issue – for example, a Python library version that is outdated or incompatible – it affects everyone, and we can solve it together.”

Preparing Students for Working Life

For Mina, using UCloud also helps prepare students for the reality that awaits them after graduation. According to her, many of the students who go on to IT positions will likely use cloud computing platforms rather than coding on local machines. In this way, the teaching becomes direct preparation for future job tasks and gives students experience with the technologies they will encounter in practice.

Advice for Other Instructors 

Mina has used UCloud since her bachelor’s degree and finds that the platform makes teaching both smoother and more engaging.

“I recommend that other instructors make use of the platform. You just have to get started – but feel free to ask colleagues for advice on how they use it. Get some inspiration, because UCloud is a fantastic tool. It can do a great many things, but like other systems, it can feel a bit overwhelming at first, so it’s a good idea to get some guidance along the way before you begin.”

A milestone reached: 20,000 users on UCloud

We are pleased to announce that even more people have discovered how UCloud can support their research – and that we have now reached an important milestone of 20,000 users.

The 20,000 users include both students and researchers, which is a truly remarkable number for a national supercomputing platform. UCloud is among the most successful High-Performance Computing platforms in Europe and stands out with a user base that is both significantly larger and more diverse than that of other – and often larger – supercomputing facilities across Europe. This applies both in terms of the number of users and the representation across research fields, levels of experience, and academic backgrounds.

Making High-Performance Computing accessible to all

UCloud was developed with a clear goal: to make High-Performance Computing accessible to all researchers affiliated with a Danish university – regardless of research area, experience, or academic discipline. We are therefore proud to see that the platform is widely used by both researchers and students across disciplines and levels.

We are pleased to help enable important research by providing the computing power needed to make research work easier and more time-efficient. At the same time, UCloud makes it possible to process sensitive data on a secure platform. Our platform is an important contribution to research that creates real value in the world beyond academia.

A milestone driven by collaboration

This milestone is the result of many years of focused work to create a platform that combines user-friendliness with high performance. It is also the result of the strong consortium collaboration between the University of Southern Denmark, Aarhus University, and Aalborg University, which jointly develop UCloud and continuously expand the platform to meet researchers’ needs.

A new data center to support the growing user base

To support the rapidly growing number of users on the platform, a new data center to host UCloud’s next-generation hardware was recently established. This expansion strengthens UCloud’s capacity and ensures that the platform is future-proof and ready to support both current and upcoming users. You can read more about the expansion here: University Collaboration Strengthens National Research Infrastructure with New Green Data Center.

University Collaboration Strengthens National Research Infrastructure with New Green Data Center 

The shared infrastructure of three Danish universities has become a significant success for research and innovation. Now, capacity is strengthened further with the establishment of a new, more energy-efficient and sustainable data center.

Over the past six years, demand for the type of interactive, user-friendly supercomputing provided by DeiC Interactive HPC has proven enormous. UCloud, the platform behind the service, now has nearly 20,000 users, including both students and researchers—a truly unique figurefor a supercomputer. Comparable – and even larger – supercomputers in Europe cannot boast even half as many users or the same broad representation across gender and research fields as UCloud.

“DeiC Interactive HPC and UCloud have, in six years, changed the way Danish researchers work with supercomputing. With UCloud, we have made advanced computing power accessible across disciplines—from students to experienced researchers—and created a platform that combines user-friendliness with high performance. It’s a success we are proud of and one that shows Denmark can lead the way in digital research,” says Marianne Holmer, Dean of the Faculty of Science, University of Southern Denmark. 

The New DeiC Interactive HPC – More Computing Power and Sustainability 

DeiC funding has been increased, and new opportunities for collaboration have emerged for the consortium behind the service, consisting of the University of Southern Denmark (SDU), Aarhus University (AU), and Aalborg University (AAU). SDU, Danfoss, and Hewlett Packard Enterprise (HPE) have entered into a collaboration to establish a new data center (link), where DeiC Interactive HPC’s hardware will be placed going forward. The new data center makes it possible to combine high-performance computing with energy-efficient and innovative cooling and heat recovery. At the same time, Danfoss’ cooling and heat recovery systems enable surplus heat from the new data center to be reused. 

The initiative is supported by ProjectZero, a public-private partnership in Sønderborg with the goal of making its energy system carbon-neutral by 2029. The project focuses on a three-step decarbonization approach of reducing, reusing, and renewing energy and has already achieved a significant reduction in energy-related carbon emissions.

The increased investment from DeiC means the consortium can deliver higher capacity to its many users. SDU, as the consortium representative, has worked with the supplier HPE to assemble a supercomputer that includes the latest and most powerful GPU hardware – essential for AI research and handling large datasets. All of this will be available in UCloud’s secure, user-friendly open-source environment.

With the new data center, we are taking a decisive step into the future of research infrastructure. We are showing that Denmark can deliver world-class supercomputing – not only in performance but also in sustainability and digital sovereignty,” says Professor Claudio Pica, Director of the SDU eScience Center. 

A Unique Contribution to Denmark’s Digital Sovereignty 

DeiC Interactive HPC is located on Danish soil and uses Danish-developed open-source cloud technology – UCloud. This allows Danish researchers to efficiently utilize supercomputer resources without relying on foreign technology providers, and in an environment suitable even for sensitive personal data.

There is currently much discussion about digital sovereignty and the challenges posed by the fact that parts of the digital infrastructure that Denmark heavily depends on is developed, owned, and controlled by foreign tech giants. Here, UCloud and the Interactive HPC collaboration are a unique example of how public institutions can develop and use secure, transparent, and sustainable digital solutions that support research, education, and society’s broader digital needs,” says Professor Kristoffer Nielbo, Head of the Center for Humanities Computing, Aarhus University. 

The consortium’s role in strengthening Denmark’s digital sovereignty was recently highlighted by a visit from the Minister for Digital Affairs, Caroline Stage Olsen. With increased capacity and a new data center, it is clear that the consortium can contribute even more to this agenda in the future. 

University Collaboration Beyond Hardware

In the new consortium setup, SDU is responsible for operating and delivering the hardware for DeiC Interactive HPC, while all three universities contribute to developing the service, maintaining and adding new apps to UCloud’s App Store, and supporting the other universities. One of the keys to DeiC Interactive HPC’s success is not just offering supercomputing power – but also the support and user-friendliness that make these powerful resources accessible to a wide range of researchers, including students.

The strength of the consortium lies in the fact that we don’t just deliver hardware, we create a shared platform where universities develop solutions together. This provides a dynamic service that is continuously adapted to researchers’ needs. By combining computing power with user-friendly tools and solid support, we open the door to new opportunities in research and innovation,” says Jacob-Steen Madsen, Deputy Director, IT Services, Aalborg University.
