  • 0

I have made an OS simulator for a project, for the next part I have to modify the simulator to include 4 CPUs in place of only 1 CPU from the previous part, so that all the processes get done in a faster time.

So I have to add concurrency but I am not sure what the right design pattern is for this kind of thing. I need to know if the following will actually give me a speed up.

CPU extends Thread

//in main

get process1
get process 2
get process 3
get process 4

cpu1.run(process1)
cpu2.run(process2)
cpu3.run(process3)
cpu4.run(process4)

am I right in assuming that because cpus are extending thread they will all run concurrently for finish the 4 processes or will it be just like running the 4 processes on a single CPU?

    By the nature of the question, this is a class project and that your representation of a cpu is relatively simple. For example, just runs a series of instructions like thread class. If however, you are trying to emulate real world CPUs and microprocessors, we need to know more about the cpu features: scheduling, event handling and other low level aspects that are normally hidden.

    But, in the simple case, the answer is generally yes.

    Note, depending on the tasks in those processes and the CPU you run this code on, you may see different behaviors because of how the CPU and JVM are actually implementing threads. But, I think in your case it isn’t relevant.
