Workshop "HPC Services for Entrepreneurs", EDIH CROBOHUB++, Srce
11 November 2025, 12:00 – 15:30
Experts from the University Computing Centre (SRCE), as part of the European Digital Innovation Hub project “CROatian Industry and Society BOosting” (EDIH CROBOHUB++), are organizing a workshop titled "HPC Services for Entrepreneurs". The workshop is intended for companies interested in learning more about the key aspects, benefits, and practical applications of high-performance computing (HPC) technologies in business and product development. The workshop consists of two parts. The first part will introduce the basics of HPC architecture and technology as well as available national and international HPC resources, aimed at beginners without prior HPC experience. The workshop will be led by Emir Imamagić, Head of the Advanced Computing Division at SRCE.
The second part of the workshop will include hands-on practice on SRCE’s computing cluster (cluster access, data storage and preparation, software environment selection, job submission and monitoring, and node performance tracking). This part is intended for more advanced users familiar with Linux. The session will be led by Marko Hrženjak, HPC expert at SRCE.
Use cases – The role of the Croatian Competence Centre for HPC
12 November 2025, 11:10 – 12:40
- "When the public helps doctors: The AI4Health.Cro Challenge", Dr. Anja Barešić, Ruđer Bošković Institute
In 2025, a hackathon was held as part of the AI4Health.Cro project, addressing the need for up-to-date AI models trained on real data from the Croatian healthcare system through crowdsourcing. The presentation will showcase the technical setup and process of the breast lesion detection challenge in mammogram images, highlighting the role of high-performance computing in developing similar medical and healthcare innovations.
- "Using supercomputers for commercial numerical simulations of ship hydrodynamics", Dr. Inno Gatin, Cloud Towing Tank by In silico
To conduct computationally intensive numerical simulations of variable scope, we need access to flexible computing resources. Our projects often vary in size and have short deadlines, so parallel execution of calculations is crucial to meeting delivery times. We are regular users of the BURA and VEGA HPC centres, which provide adequate processing capacity and cost-effective resources. The presentation will show examples from our commercial projects, with more details on required resources, delivery time, and computation goals.
- "Password security analysis", Prof. Toni Perković, University of Split, Faculty of Electrical Engineering, Mechanical Engineering and Naval Architecture
We conducted a password security analysis using the Hashcat tool and Hashtopolis system. Hashcat enables efficient cracking of hashed passwords through methods such as brute-force and dictionary-based attacks, while Hashtopolis allows distributed management of attacks across multiple HTC machines. This combination provides a scalable and flexible approach to password security analysis, improving the efficiency and speed of detecting potentially weak passwords. For this research, we used the Supek and Vrančić supercomputers, employing virtualization tools to test password resistance to various attacks. Such resources enabled the rapid execution of complex experiments and a practical insight into user data protection strength.
