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.

We look forward to welcoming even more users to UCloud – and to continuing to support Danish research with modern, scalable, and secure supercomputing infrastructure.

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.

UCloud 2025.4.0 Release

Command palette, integrated editor & terminal, faster file search and a simpler Syncthing UI. Today we’re releasing UCloud 2025.4.0! This update introduces a keyboard-driven command palette, a built-in text editor, an integrated terminal, a fully revamped file search, and a simplified Syncthing experience.

While these new tools will be the most visible changes for users, they are also part of a broader, long-term effort to refine UCloud’s foundations.

“Software development on UCloud started back in 2017. Since then, we have make many architectural and design changes. This progress inevitably caused a build-up of inconsistensies and inefficiencies. With our understanding of the goal now being a lot clearer than in 2017, the aim is to simplify the internal code structure and get rid of old legacy code to ensure stability, performance and faster development of the service.”

Dan Sebastian Thrane, Senior Software Architect for Research Infrastructure

With that context in mind, here’s a closer look at what’s new in UCloud 2025.4.0.

Navigation and shortcuts

We have added a fast way to move around UCloud without leaving the keyboard.

  • Keyboard-first workflow: Use it to access shortcuts to common actions, jump to your favorite applications, or quickly switch projects.
  • Command palette: Open the palette with Ctrl+P on Windows/Linux or Cmd+P on macOS.

Files and search

Finding things is now much quicker and more reliable and edit text files directly in UCloud without needing to start a job.

  • Revamped file search: File search has been completely rebuilt and is now significantly faster. This requires your files to be indexed. Indexing of files may take up to 24 hours after the file has been created.
  • Edit-in-place: Double-click any text file in the file browser to open it in the new integrated editor.
  • Syntax highlighting: The editor supports basic syntax highlighting.
  • Tabs & file tree: Work across multiple tabs and use the sidebar to navigate your project’s file tree quickly.

Integrated terminal

A lightweight terminal is now available across Kubernetes-based service providers.

  • Auto-shutdown: Sessions shut down automatically when inactive. (Do not use it for long-running or background tasks.)
  • Availability: The integrated terminal is now available on the SDU/K8s provider. It works similar to the terminal released last year for the SDU/Hippo provider. You can open a terminal in any folder via “Open terminal” button.
  • For small tasks: Ideal for quick edits and running common utilities.
  • Resource limits: The terminal has low CPU and memory and (is not intended for running jobs).

Jobs and Syncthing

New real-time metrics have been added to jobs and the Syncthing has been made easier to understand and operate.

  • Simplified interface: A cleaner, more approachable Syncthing UI for managing synchronization.
  • Real-time job metrics: You can now monitor real time metrics about CPU, memory and GPU utilization from the job view.

Improved data transfer

The integration module has received a large upgrade to the upload protocol.

  • This protocol is used both by end-users and between service providers.
  • Data transfer between the SDU and AAU provider is now much easier and faster.
  • The upload protocol is smart and attempts to avoid sending files which are already present. It also utilizes multiple TCP streams and threads to maximize performance.
