When parallelizing an application, the ideal speedup is speeding up by the number of processors. this is limited by two things: percentage of the application that can be parallelized and the cost of communication. amdahl’s law takes into account the former but not the latter. a. [10] < 1.10> what is the speedup with n processors if 80% of the application is parallelizable, ignoring the cost of communication? b. [20] < 1.10> what is the speedup with 8 processors if, for every processor added, the communication overhead is 0.5% of the original execution time. c. [20] < 1.10> what is the speedup with 8 processors if, for every time the number of processors is doubled, the communication overhead is increased by 0.5% of the original execution time?

Me with this program in c++ ! computers represent color by combining sub-colors red, green, and blue (rgb). each sub-color's value can range from 0 to 255. thus (255, 0, 0) is bright red. (130, 0, 130) is a medium purple. (0, 0, 0) is black, (255, 255, 255) is white, and (40, 40, 40) is a dark gray. (130, 50, 130) is a faded purple, due to the (50, 50, 50) gray part. (in other word, equal amounts of red, green, blue yield gray).given values for red, green, and blue, remove the gray part. ex: if the input is 130 50 130, the output is: 80 0 80. thus, find the smallest value, and then subtract it from all three values, thus removing the gray.
