Аннотация:Administering of supercomputer centers is a complicated task. Traditional practice is to use numerous tools separately for user accounting, user support, license accounting and all other routines. This leads to errors like missed procedure steps, data loss and many other human-factor aspects not to mention loss of time. The developed Octoshell HPC center management system replaces variety of essential tools in a single interface and distribute typical routines between modules. The system and consequently intermodular interactions are becoming more complicated at the moment limiting system exibility. The proposed method will organize interaction between modules to ease module development in Octoshell and make the system more flexible.
