Process Dispatching

• After assignment, deciding who is selected from among the pool of waiting processes
  • Process dispatching.
• Single processor multiprogramming strategies may be counter-productive here.
• Priorities and process history may not be sufficient.

Process Scheduling

• Single queue of processes or if multiple priority is used, multiple priority queues, all feeding into a common pool of processors.
• Multi-server queuing model: multiple-queue/single queue, multiple server system.
  • Inference: Specific scheduling policy does not have much effect as the number of processors increase.
• Conclusion: Use FCFS with priority levels.
