This page provides a brief overview of batch system concepts. It is provided as a foundation to understanding the system for running jobs on the Sierra compute clusters.

Livermore Computing (LC) provides a large variety of High Performance Computing (HPC) clusters.  However, there are only two batch schedulers that run user jobs on those clusters.  Slurm is the batch scheduler and resource manager that schedules almost all LC clusters.  The exception is the IBM Sierra clusters (aka CORAL systems) which run the Spectrum LSF scheduler.

Useful introductory information on LC's software environment is presented in the Software and Development Environment section of the Introduction to Livermore Computing Resources, or the Linux Clusters Overview for system-specific information.

This page lists available online tutorials related to parallel programming and using LC's HPC systems.
