This page lists available online tutorials related to parallel programming and using LC's HPC systems.
Forms are provided for those requests not available through the LC IdM System. Interactive HTML and PDF versions are forms you complete on the Web. Non-interactive PDF versions are to print out and complete by hand.
NICE DCV is a Virtual Network Computing (VNC) server that provides a securely authenticated and encrypted way for users to create and view a virtual desktop that persists even if no client is actually viewing it.
We are scheduling large dedicated application runs on M&IC machines, usually during a weekend. Some of these runs may require that the entire machine be dedicated to them.
Both Slurm and IBM's CSM provide a way to launch tasks (aka, Linux processes) of a user's application in parallel across resources allocated to the job. For Slurm, the command is srun; for CSM, the command is jsrun. This page presents their similarities and their differences. It also details lrun, an LLNL developed wrapper script for jsrun.
IBM Spectrum LSF is a batch scheduler that allows users to run their jobs on Livermore Computing’s (LC) Sierra (link is external) (CORAL) high performance computing (HPC) clusters. IBM Cluster System Management (CSM) is the resource manager for the Sierra systems.

Slurm is a combined batch scheduler and resource manager that allows users to run their jobs on Livermore Computing’s (LC) high performance computing (HPC) clusters. This document describes the process for submitting and running jobs under the Slurm Workload Manager.
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.
