Overview
Slurm, which stands for Simple Linux Utility for Resource Management, is a widely used open-source HPC resource management and scheduling system that originated at Lawrence Livermore National Laboratory.
All others should contact OSC Sales for pricing information.
Job charging based on usage
OSC offers the use of budgets to limit the amount of charges incurred on projects.
Active budget
Once a budget has been approved, it (and the project it was requested from) becomes active. Having an active project allows users on that project to submit batch jobs to use OSC resources.
