IBM® Tivoli® Workload Scheduler (TWS) LoadLeveler® enables users to run more jobs in less time

It is a parallel scheduling system that matches each job's processing needs and priority with available resources and special instructions for maximum resource utilization.

Delivers tight control of resources: can limit use of individual machines to specific times, users or job classes, or can use machines only when the keyboard and mouse are inactive
Tracks the total resources used by each serial or parallel job and offers several reporting options to track jobs and utilization by user, group, account or type over a specified time period
Can incorporate machine speed to adjust chargeback rates and be configured to require an account for each job to support chargeback for resource use
Offers both a command line interface and a graphical interface in addition to an API enabling user-written applications to control it
Supports high-availability configurations to ensure reliable operation, and automatically monitors available compute resources to ensure that no jobs are scheduled to failed machines
Integrates with AIX® Workload Manager (WLM) and the IBM High Performance Switch (HPS) for System p™ hardware, and includes an algorithm for the Blue Gene® machine BG/L
