HPCnix: make HPC Apps more easier like shell script

In the area of high-performance computing (HPC), it is expected to extract extreme computing performance using a highly optimized framework without even common OS APIs and frameworks for personal desktops. However, this makes the development cost higher than normal application development and challenging for beginners. The demand for large-scale computation is increasing due to the growth of cloud computing environments and the AI boom resulting from deep learning and large-scale language models. Therefore, a framework that makes it easier to handle HPC application programming is needed. This study shows a concept model that makes it possible to write HPC applications using semantics like the shell command pipeline in Unix. It proposes a simple application framework for beginners in HPC called HPCnix.
