Final answer:
To find the total execution time for the program on different processors and determine the speedup, we need to consider parallel processing and divide the tasks among multiple processors.
Step-by-step explanation:
To find the total execution time for this program on 1, 2, 4, and 8 processors, we need to consider the concept of parallel processing. In parallel processing, tasks are divided among multiple processors, and each processor works on a subset of the tasks simultaneously.
To calculate the total execution time, we divide the number of tasks by the number of processors. For example, if the program has 100 tasks and we are using 4 processors, each processor will work on 100/4 = 25 tasks. The time taken by each processor to complete its tasks is the same, as they are happening in parallel. So the total execution time will be the time taken by the slowest processor.
To calculate the relative speedup of the 2, 4, and 8 processor results relative to the single processor result, we can divide the execution time of the single processor result by the execution time of the multi-processor results.
