_smartShare

Configuring SmartShare

• supervisor_smart_share_mode
  • Can be either “jobs” or “none”.  
  • default: "jobs"
  • Setting it to “jobs” will make the system try to balance the number of the automatically-expanded “secondary" instances on a job-to-job basis
  • Setting it to “none” disables SmartShare. 
• supervisor_smart_share_preempt_policy
  • method of preemption for secondary instances 
  • aggressive, passive, disabled
  • default: aggressive
• supervisor_default_max_cpus
  
  • used to set the site-wide default value of “max_cpus” if not given at submission
  • default: -1
  • Note: “*” can be used in the qb.conf file too, instead of -1
• supervisor_max_cpus_limit
  
  • largest value of “max_cpus” that can be used on any job
  • default 100
  • Note: if any job specifies a value greater than this, the system will silently cap it to this value
