The Impact of Symmetric Multicore Processor on Computing

The emergence of multiprocessor architecture, such as a symmetric multicore processor (SMP), has revolutionized the computing industry by offering an environment for parallel computing with improved performance. In this context, this paper aims to analyze the impact of SMP on computing by looking at the following code: Core 1: x=2; Core 2: y=2; Core 3: w=x+y+1; Core 4: z=x+y; This code is running on four processors in an SMP, and the initial values of x and y are 0. In this case, the possible resulting values of w, x, y and z can be 0, 2, 3, and 4 respectively, depending on the order of execution of the instructions. For example, if the instructions are executed sequentially, the result would be (w,x,y,z)=(3,2,2,0). On the other hand, if the instructions are executed simultaneously, the result would be (w,x,y,z)=(4,2,2,2). To make the execution more deterministic, one way is to use locks and semaphores (Liang, 2022). By using locks, the operating system can ensure that a. Cont…
