Load Sharing Facility

LSF Suite 3.2.3 is a collection of resource-management products that provide distributed batch scheduling, load balancing, job execution, and job termination services across a network of computers. The LSF products required by Sun HPC ClusterTools 3.0 software are: LSF Base, LSF Batch, and LSF Parallel.

• LSF Base - Provides the fundamental services upon which LSF Batch and LSF Parallel depend. It supplies cluster configuration information as well as the up-to-date resource and load information needed for efficient job allocation. It also supports interactive job execution.

• LSF Batch - Performs batch job processing, load balancing, and policy-based resource allocation.

• LSF Parallel - Extends the LSF Base and Batch services with support for parallel jobs.

Refer to the LSF Administrator's Guide for a fuller description of LSF Base and LSF Batch and to the LSF Parallel User's Guide for more information about LSF Parallel.

LSF supports the concept of interactive batch execution of Sun HPC jobs as well the conventional batch method. Interactive batch mode allows users to submit jobs through the LSF Batch system and remain attached to the job throughout execution.
