Your Trusted Partner for IBM Spectrum LSF to PBS Pro Migration
Yes, migrating IBM Spectrum LSF to Altair PBS Professional is a well-understood project. You get a fixed-scope project run by senior platform engineers, so you move to a unified, commercial HPC scheduler on
The lowest-cost way off IBM Spectrum LSF: our migration tooling automates the repetitive work —you pay senior engineers for judgment, not keystrokes.
How we support IBM Spectrum LSF → Altair PBS Professional after migration
- ✓Fixed-scope migration project with senior engineers.
- ✓Independent support of active LSF during transition.
- ✓Neutralizes IBM leverage at renewal negotiations.
- ✓40–70% savings on legacy support while you plan.
- ✓24/7 US-based support for your new PBS cluster.
- ✓Typical project: 3–5 months, $75K–$350K.
LSF multicluster features
Your LSF multicluster topology is complex. We map every job-route and sharing boundary to PBS, ensuring nothing breaks.
Host/queue partition limits
LSF-specific host and queue partition parameters don't transfer automatically. We manually configure equivalents in PBS.
Custom resource connector integrations
Your custom resource connectors tie LSF to your CAE toolchain. We rebuild them for PBS without lost capability.
IBM Spectrum LSF → Altair PBS Professional migration — your questions answered
Why move from IBM Spectrum LSF to Altair PBS Professional?+
Driven by dissatisfaction with IBM software support and licensing costs, standardization on Altair CAE/simulation suites, and corporate mandates to consolidate onto a unified commercial HPC scheduler.
How do you handle LSF multicluster features in PBS?+
We map every multicluster job-routing rule and resource-sharing boundary to PBS Professional equivalents during the 3-5 month fixed-scope project. No hidden gaps.
Do I lose functionality from LSF-specific host/queue partition limits?+
No. We catalog every LSF partition parameter on your environment, then manually configure the same behavior in PBS. Nothing is assumed or dropped.
What happens to my custom resource connector integrations?+
We rebuild each custom connector from LSF to PBS Professional as part of the project. Your CAE toolchain keeps working without interruption.
Move to Altair PBS Pro with Full Support of Your Active LSF
Your IBM Spectrum LSF contract stays active through your renewal — so you migrate on your timeline, not IBM's. If your renewal lapses, our third-party support handles operational issues on the legacy platform while you complete the move. Post-migration, we offer ongoing PBS cluster administration, optimization, and patching. Start with a free LSF to PBS Professional Compatibility Assessment.
