User interface for a computational cluster: resource description approach

Computational centers provide users with HPC resources. This usually includes not only hardware (e.g. powerful computational clusters) and system software (e.g. Linux and some PBS implementation), but also application software too. In case of university computational center system administrators install some scientific applications, provide users with access to them and manage that access. They are usually responsible for updating such software and solving problems. But such access usually implies only the ability to submit user jobs to resources: users are responsible for creating correct job description (in terms of necessary resources) and job start script (conventional and widely used systems like PBS usually require some script which contains commands that actually start the job). But inexperienced users could spend much time to learn the interface. They could do mistakes which could lead to imbalance in system utilization. This article propose an interface that will provide uses with conventional interface. Using this approach computational center users could avoid scripting and concentrate on their job.
