JobScheduler Master supports Fixed Priority Scheduling and Round-Robin Scheduling for Tasks with Agents

Current Behavior

• Two Agents are configured for an Agent Bundle with a process class
  • Agent 1 and Agent 2 are both available.
  • Tasks are executed alternately on both Agents (round-robin).

Desired Behavior

• JobScheduler should support both Round-Robin Scheduling and Fixed Priority Scheduling.
• The behavior can be configured with Fixed Priority Scheduling being the default.

Fixed Priority Scheduling

• JobScheduler Master selects the first available Agent from the process class configuration. Jobs will be executed on a different Agent exclusively in case that the first Agent becomes unavailable.
• This behavior is intended for fail-over of Agents.
• Process class configuration:

  <process_class>
      <remote_schedulers select="first">
          <remote_scheduler  remote_scheduler="http://agent1:4445"/>
          <remote_scheduler  remote_scheduler="http://agent2:4445"/>
      </remote_schedulers>
  </process_class>
  

Round-Robin Scheduling

• JobScheduler Master selects the next available Agent from the process class configuration. Jobs will be carried out alternately on each available Agent.
• This behavior is intended for balanced execution of tasks on a number of Agents.
• Process class configuration:

  <process_class>
      <remote_schedulers select="next">
          <remote_scheduler  remote_scheduler="http://agent1:4445"/>
          <remote_scheduler  remote_scheduler="http://agent2:4445"/>
      </remote_schedulers>
  </process_class>
