The Model

• Problem: Real systems do not know a job’s CPU or memory requirements on arrival.

• We consider static systems (no reassignment).

• The scheduler does not know a job’s memory or CPU requirements until after placing the job.

• Once it places a job, it knows the revised load on that machine.

Otherwise, the model remains the same as for the Enhanced PVM Strategy.
