Abstract


This article presents the development and implementation of the portable HybriLIT cluster—a lightweight HPC platform designed for educational purposes. The growing need for training in parallel computing and HPC systems requires accessible and realistic tools for preparing students and professionals. Portable HybriLIT replicates key elements of a modern computing infrastructure, including SSH access, a module environment, the SLURM task scheduler, and support for multiprocessor computing (CPU and GPU), providing a realistic experience of practical use the HPC system. The main advantages of the proposed solution are low cost, ease of assembly, and the ability to operate autonomously without an internet connection, which is especially relevant for mobile schools, hackathons, and training courses in remote regions. The article provides a hardware and software description of the cluster, examples of its use in educational activities, statistics on completed courses, and recommendations for creating similar solutions at other educational institutions.
