Tivoli Workload Automation

Overview

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
• "Solution Sheet: Maximize operational efficiencies and business resiliency"
• Operating systems supported: AIX, Linux
