WebThe short answer is: it just tells you where programs are spending their time at. For a longer answer, I'll explain this in two steps. First: 1. Entering kernel mode. Every regular code you write, runs in "user mode". Programs can use libraries to do common tasks for them. This is also user mode code. WebWhen run in parallel on four processors, with each image requiring 14 14 seconds, the program takes 18 18 seconds to run. We calculate the speedup by dividing 60 60 by 18 18: 60/18 = 3.\overline {33} 60/18 = 3.33. We do not achieve a speedup of exactly 4 4, despite using that many processors. dash dumpsters crestview fl
