Concept of preservation system for scientific experiments in hpc

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