this poster presents a concept of a preservation system for computations on High Performance Computing (HPC) resources. It covers some important challenges and possible solutions related to the preservation of scientific experiments on HPC systems for their further reproduction. Storage of the experiment as only a code with some related data is not completely enough for its future reproduction, especially in the long term. Preservation of the whole experiment’s environment (operating system, used libraries, environment variables, input data, etc.) using containerization technology (e.g. Docker, Singularity) is proposed as a suitable solution for that. This approach allows to preserve an entire environment, but leaves a problem, how to deal with the commercial software that was used within the experiment. As a solution authors propose to replace during the preservation procedure all commercial software with their open source analogues, what should allow future reproduction of the experiment without any legal issues. The prototype of such a system was developed, the poster provides a scheme of the system and the first experimental results.
