Web15 de abr. de 2024 · 1. If your program doesn't have multiple threads in the source and if the compiler does not insert automatic parallelization, the program should run on a single core (at a time). Now depending on your compiler you can use appropriate optimization levels to ensure that it doesn't parallelize. 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.
