Workload Management with LoadLeveler

IBM LoadLeveler is a very effective tool for managing serial and parallel jobs over a cluster of servers. This IBM Redbooks publication describes the new tools and functions supported by LoadLeveler Version 3.1, such as new schedulers, checkpointing of jobs, AIX WorkLoad Manager integration, and so on, and includes example scenarios. Performance tuning of large clusters, and the use of external schedulers, are also featured in this book.

This book will help LoadLeveler administrators by providing a quick guide to installation procedures; we also discuss how to exploit various LoadLeveler features with sample scenarios.

Joseph F Skovira joined IBM in 1979 and has been working with parallel processors since 1987. As part of the team responsible for the deployment and operation of the SP2 at the Cornell Theory Center, he helped introduce the first BACKFILL Scheduler to the IBM SP2 in 1995. This work led to the development of the LoadLeveler external scheduling API. Involved with LoadLeveler and parallel job schedulers for the past several years, he is also interested in parallel algorithms for genomic applications, signal processing, and computational neuroscience.
