h1. Batch Systems

{tip}
The planned batch systems at LinkSCEEM-2 resources include:
* PBS (Portable Batch System or equivalent, eg. torque)
* SGE (Sun Grid Engine family or equivalent)
* SLURM (Simple Linux Utility for Resource Management or compatible)

Users are advised to check each individual HPC system to identify the available batch system and refer to the original manufacturer's documentation accordingly.
