In Problem 5.12, we were able to reduce the CPE for the prefix-sum computation to 3.00, limited by the latency of floating-point addition on this machine. Simple loop unrolling does not improve things.
Using a combination of loop unrolling and reassociation, write code for a prefix sum that achieves a CPE less than the latency of floating-point addition on your machine. Doing this requires actually increasing the number of additions performed. For example, our version with two-way unrolling requires three additions per iteration, while our version with four-way unrolling requires five. Our best implementation achieves a CPE of 1.67 on our reference machine.
Determine how the throughput and latency limits of your machine limit the minimum CPE you can achieve for the prefix-sum operation.

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.)

Many prestigious universities have a system called a “legacy preference system” which is used to decide which applicants should be accepted to the university. if an applicant’s parent is an alumnus of the university, the applicant will be admitted with lower gpa and sat scores than if the parent is not an alumnus. (there is currently a lot of discussion about the fairness of this system, but universities get a lot of money from their alumni so they are unwilling to change ) your assignment for mp2 is to implement a computerized system like this for a very small prestigious university. the university has two schools, liberal arts and music, each with their own criteria for accepting students. your program must read in certain information about an applicant and print a message saying whether the applicant should be accepted or not.
