    Configuring SmartShare

     

    Tip

    SmartShare is automatically enabled for new 6.6+ installs and upgrades alike.

    Disabling SmartShare

    To opt out, the site administrator can set the supervisor_smart_share_mode to "none" in qb.conf on the supervisor machine:

    Code Block
    supervisor_smart_share_mode = none


    • 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
