Platform LSF Session Scheduler
Platform LSF Session Scheduler addresses the need for efficient scheduling and dispatching
large volumes of independent jobs with short run times. Platform LSF Session Scheduler is a
separate add-on product like LSF License Scheduler and LSF MultiCluster.
As clusters grow and the volume of workload increases, the need to delegate scheduling
decisions increases. While traditional Platform LSF job submission, scheduling, and dispatch
methods such as job arrays or job chunking are well suited to a mix of long and short running
jobs, or jobs with dependencies on each other, Session Scheduler improves throughput and
performance of the LSF scheduler by enabling multiple tasks to be submitted as a single LSF
job.
Session Scheduler implements a hierarchal, personal scheduling paradigm that provides very
low-latency execution. With very low latency per job, Session Scheduler is ideal for executing
very short jobs, whether they are a list of tasks, or job arrays with parametric execution.
