Background:

There are several distinct types of provisioning that might need to be done before a jobs can run. So far PBS has two:

• Provisioning of the Application Operating Environment (aoe) - OS, applications, etc
• Provisioning of the Power Operating Environment (eoe) - power awareness settings

This RFE would introduce a third:

• Provisioning of the Infrastructure Operating Environment (ioe) - hardware configuration

These three operations have a hierarchical relationship: ioe then aoe then eoe

Use cases for ioe:

• configuring KNL memory models
• resetting the HPE system cache configuration
• enabling/disabling hyperthreading in system BIOS

Requirements:

• Provisioning an ioe shall follow all the same rules as provisioning an aoe, specifically:
  • A host shall list which ioe's it supports
  • A host shall list which ioe is currently instantiated (if any)
• A job shall be able to request which ioe(s) it needs to run on a per chunk basis
  
  • Different chunks can specify a different ioe or no ioe at all
• It shall be possible to provision multi-vnode hosts with a new ioe
• If more than one type of provisioning task is requested by a job they shall take place in the following order:
  1) ioe
  2) aoe
  3) eoe
