Using amdahl’s lawcalculate the speedup gain of an application that has a 60 percent parallel component for (a) two processing cores and (b) four processing cores. (10 pts) amdahl’s law is speedup < = 1 / (s + (1 –s) / n) where s is the portion of the application that must be performed serially, and n is the number of processing cores. (a) for 2 processing cores and 60 percent parallel component s is 40 percent or 0.4 and n is 2. so, speedup is < = 1/ (0.4 + (1 –0.4)/2) -> speedup < = 1.428571 -> speedup gain is 1.428 times. (b) for 4 processing cores and 60 percent parallel component s is 40 percent or 0.4 and n is 4. so, speedup is < = 1/ (0.4 + (1 –0.4)/4) -> speedup < = 1.81-> speedup gain is 1.81 times.

This first part of the film shows the early history of motion pictures. how accurate do you think the portrayal of the early motion picture industry is? why? is historical accuracy important in films and theatre productions? explain. in the scene where don is going to the party (starting at time code 14: 51), we see a street scene as he first rides with cosmo and then with kathy. what aspects did the filmmaker include to make the scene look and feel like don, cosmo, and kathy are riding in a car on a street? think about elements such as scenery, sound, props, lighting, and so on. a "talkie" picture is shown starting around time code 21: 15. how does the audience in the film react to the "talkie"? what influence do audiences have on film and theatre performances? how do film and theatre actors influence audiences? in the musical scene with cosmo (starting at time code 27: 00), how does the actor use props? what is the result? do you think the use of props effectively fulfilled the artistic vision for this musical number? why or why not?

The fourth generation of computers emerged between 1970s and 1980s. which technological advancement brought about this generation of computers? which computer architecture was used most in this generation?

Jason, samantha, ravi, sheila, and ankit are preparing for an upcoming marathon. each day of the week, they run a certain number of miles and write them into a notebook. at the end of the week, they would like to know the number of miles run each day, the total miles for the week, and average miles run each day. write a program to them analyze their data. your program must contain parallel arrays: an array to store the names of the runners and a two-dimensional array of five rows and seven columns to store the number of miles run by each runner each day. furthermore, your program must contain at least the following functions: a function to read and store the runners’ names and the numbers of miles run each day; a function to find the total miles run by each runner and the average number of miles run each day; and a function to output the results. (you may assume that the input data is stored in a file and each line of data is in the following form: runnername milesday1 milesday2 milesday3 milesday4 milesday5 milesday6 milesday7.)
