Altair Engineering Releases PBS Professional Version 7.0 with Expanded Workload Capacity and Enhanced Systems Resiliency

TROY, Mich. May 17, 2005 - Altair Engineering, a global leader in product design consulting, engineering software and high-performance computing technology, today announced the release of PBS ProfessionalTM 7.0, the next generation of its Portable Batch System (PBS) technology that helps customers optimize the utilization of enterprise computing environments by intelligently aggregating and scheduling computational resources. Altair made this announcement from the Bio-IT World Conference + Expo in Boston.

PBS Professional 7.0 continues to raise the standard of workload management solutions by delivering significant advancements. This release includes:

  • expanded capacity for very large workloads

  • enhanced integration with MPI libraries

  • extended support for unique features within SGI’s Altix environment

"PBS Professional version 7.0 broadens our market appeal with the addition of Job arrays. Bioinformatics, Financial services and animation customers who manage very large workloads will realize significant productivity gains with PBS Professional v7.0," said Michael Humphrey, vice president of enterprise computing for Altair.

Job Arrays Function - PBS Professional now supports Job Arrays. Job Arrays is a mechanism for grouping related work, allowing the user to submit, query, modify and display a set of jobs as a single unit. This new feature is particularly useful for users who submit and manage very large quantities of related jobs.

"Here at the Translational Genomic Research Institute (TGen), we deployed PBS Professional on our 1,048-CPU IBM 1350 eCluster supercomputer to manage a diverse workload. We believe the new Job Array functionality provided with version 7.0 will help us manage our bioinformatics jobs more efficiently and allow our scientists to be more productive," said James Lowey, manager for high performance computing systems at TGen.

MPI Library Integration - PBS Professional 7.0 provides a higher level of integration with select MPI libraries, resulting in improved resiliency under a variety of system failure modes. This tighter integration within PBS Professional 7.0 minimizes the need for epilogue scripts when a system failure occurs within a set of nodes running a MPI job. PBS Professional 7.0 includes tighter integration with the following MPI libraries:

  • MPICH running on Intel and AMD based Linux clusters

  • IBM POE running on IBM systems running AIX

"The MPI integration work released in PBS Professional 7.0 is a continuation of our focus to add resiliency to our product and make it easier for systems administrators" stated Dr. Bill Nitzberg, chief technology officer for Altair Grid Technologies. "We will be releasing tighter integrations with additional MPI libraries in our next couple of releases as well."

SGI Altix specific features - PBS Professional is a popular workload manager for SGI’s Altix systems. PBS Professional 7.0 includes additional new features unique to the Altix environment:

  • Support SGI’s Process Aggregation Groups (PAGG) on Altix systems

  • Support SGI’s ProPack 4 for Altix systems

  • Integration with SGI’s CSA for Altix systems

"Altix customers have selected PBS Professional for their workload management requirements because Altair has continuously added new features to exploit the scalability and performance of our Altix systems. We are pleased to see Altair continue this trend with their 7.0 release of PBS Professional. Our partnership with Altair has been a win-win proposition for all parties involved-especially our customers," said Anneke Dempsey, Senior Director of Global Alliances for SGI.
