Hi, I am happy to announce that PBS Professional 2022.1.0 is now available!

The release and documentation are now live on the PBS Professional User Area, Altair Connect, and Altair One Marketplace.

This release brings many exciting new features to customers, including:

Greatly increased flexibility and customization options for complex site-specific needs via new server host plug-in trigger points:​

  • When a job ends​
  • When configuration change is made via management interface (qmgr)​
  • When nodes change state​
  • When a reservation is confirmed, begins, or is modified​
  • When a job enters an execution queue​

Changing priorities and requirements can be accommodated by adding nodes/resources to running reservations​

Increases in robustness and ease of maintenance:

  • Multi-node jobs can continue to run through pbs_mom restart
  • Scheduler can be run as non-root user​

Performance:

  • ~500% job deletion speedup (qdel)
  • Additional performance/throughput improvements​

Cloud Bursting:

  • “Simulator Driven” Bursting​
    • Optimized cloud bursting to minimize costs & maximize successful bursting​
    • Simulator estimates cloud resources needed (all select & place options supported)

Budgets:

  • “Cloud Cost Integration”​ allows sites to allocate cloud costs against Budget​:

    • Target cloud & on-Prem jobs with different cost models​
    • Utilize a single formula (e.g. $'s) or multiple (e.g. core_hours & cloud_hours)​
  • Cloud Cost API​:
    • Interface to map instances costs to cloud accounts​
  • Budget Aware Cloud Bursting:
    • Consider budget availability before bursting​
