IBM® Tivoli® Workload Scheduler (TWS) LoadLeveler® for AIX® is a distributed network-wide job management facility designed to dynamically schedule work on IBM UNIX® servers, such as the IBM Power Systems and IBM BladeCenter® servers. It allows users to run more jobs in less time by matching the jobs' processing needs with the available resources. Version 3.5 enhancements include:

  • Recurring reservations
  • Data-aware scheduling for improved cluster utilization
  • Multicluster scale-across scheduling
  • AIX Work Load Management (WLM) integration
  • Adapter striping
  • Task affinity

For ordering, contact your IBM representative, an IBM Business Partner, or IBM Americas Call Centers at 800-IBM-CALL (Reference: RE001).

TWS LoadLeveler for AIX is a job management system that allows users to run more jobs in less time by matching the jobs' processing needs with the available resources. TWS LoadLeveler schedules jobs and provides functions for building, submitting, and processing jobs quickly and efficiently in a dynamic environment. Batch jobs can be submitted, either serial or parallel, to run in the background and require no input from the user.

Version 3.5 enhancements include:

  • The TWS LoadLeveler commands and APIs have been enhanced to support recurring reservations. Accounting records have been enhanced to have recurring reservation entries. A new "recurring" job command keyword will allow a user to specify that the job can run in every occurrence of the recurring reservation to which it is bound.
  • Data-aware scheduling support is designed to improve cluster utilization and performance in data-intensive applications. With the new support, data staging can be scheduled to occur at submit time, just-in-time, or ahead of a reservation.
  • Scale-across scheduling is a way to schedule jobs in the multicluster environment to span resources across more than one cluster. This feature allows jobs that request more resources than any single cluster can provide to combine the resources of multiple clusters to run that job, effectively spanning resources across more than one cluster. Additionally, it allows utilization of fragmented resources from more than one cluster. Fragmented resources occur when the resources available on a single cluster cannot satisfy any single job on that cluster. This feature allows any size job to take advantage of these resources by combining them from multiple clusters.
  • Enhancements to AIX WLM integration for virtual memory and large page usage of a job includes reporting statistics for limits and dynamically changing and enforcing limits.
  • Enhanced adapter striping (sn_all) support allows scheduling of jobs to nodes that have a few networks in the failed (NOTREADY) state provided that all of the nodes assigned to the job have more than half of the networks in the READY state. A new "striping_with_minimum_networks" configuration keyword has been added to the class stanza to support striping on failed networks.
  • Task affinity support has been enhanced on nodes that are booted in single threaded mode and on nodes that do not support simultaneous multithreading (SMT).

IBM Electronic Services
Bottom rule

IBM has transformed its delivery of hardware and software support services to help you achieve higher system availability. Electronic Services is a Web-enabled solution that offers an exclusive, no-additional-charge enhancement to the service and support available for IBM servers. These services are designed to provide the opportunity for greater system availability with faster problem resolution and preemptive monitoring. Electronic Services comprises two separate, but complementary, elements: Electronic Services news page and Electronic Services Agent.

The Electronic Services news page is a single Internet entry point that replaces the multiple entry points traditionally used to access IBM Internet services and support. The news page enables you to gain easier access to IBM resources for assistance in resolving technical problems.

The Electronic Service Agent™ is no-additional-charge software that resides on your server. It monitors events and transmits system inventory information to IBM on a periodic, client-defined timetable. The Electronic Service Agent automatically reports hardware problems to IBM. Early knowledge about potential problems enables IBM to deliver proactive service that may result in higher system availability and performance. In addition, information collected through the Service Agent is made available to IBM service support representatives when they help answer your questions or diagnose problems. Installation and use of IBM Electronic Service Agent for problem reporting enables IBM to provide better support and service for your IBM server.
