The Paderborn Center for Parallel Computing (PC2) has introduced PERSEUS, a new open-source software designed to make the operation of scientific high-performance computing centers (HPC) more efficient and professional. The first beta version has been published on September 22nd, 2025.
The software decisively solves the most pressing challenges in the area of compute projects and the associated administrative processes. PERSEUS offers a highly dynamic approach to data management. This approach allows to store all relevant information in one place. A key feature is that even if certain data is unavailable or removed, the processes remain functional. This is crucial for the high availability of the systems and critical infrastructure.
“With PERSEUS, we are creating a solution that makes everyday life in scientific computing centers noticeably easier,” says Prof. Dr. Christian Plessl, managing director of PC2. “Our software bundles data, automates processes, and at the same time remains flexible enough to respond to the individual requirements of different institutions.”
A core feature of PERSEUS is user-defined workflows, known as states. Each proposal for computing time and the associated compute projects are linked to a workflow engine that coordinates all processes. This allows HPC centers to flexibly adapt and optimize their internal processes. In addition, the software supports the automation of professional processes. To achieve this, so-called services can be developed that provide specific functionalities – either directly via the front end for employees or via a standardized REST API for external applications.
An initial evaluation at PC2 showed promising results: Access times to project-related data were reduced by approximately half on average. At the same time, user confidence in the consistency and reliability of the data is increasing. “The completeness, speed and reliability of access to project data is extremely important for ongoing operations and good customer support,” emphasizes Dr. Jens Simon, head of HPC operations at PC2. “The fact that we have been able to achieve such significant improvements here with PERSEUS speaks for the efficiency of our new solution.”
The center-specific expandability of PERSEUS was also convincing. “From a technical point of view, thanks to its modular structure, clearly defined interfaces, and good documentation, we can implement new states and services in a short time - this keeps PERSEUS adaptable and future-proof,” says Lukas Ostermann, Principal Software Engineer at PC2. Supported by PC2 software developers Marcel Wilkowsky and Marian Hahne, the initial idea became a professional software solution that is now publicly available.
With PERSEUS, PC2 is sending a clear signal for open, flexible, and future-proof software solutions in the field of high-performance computing.
