Question: Consider the feedback model of a CPU and I/O device of Example with the difference that the CPU consists of m identical parallel processors. The service time of a job at each parallel processor is exponentially distributed with mean 1/μI. Derive the stationary distribution of the system.
Example: Consider a model of a computer CPU connected to an I/O device as shown in Fig. Jobs enter the system according to a Poisson process with rate λ, and use the CPU for an exponentially distributed time interval with mean 1/μ1.
