Assume that a computation comprises k + 1 distinct tasks. In order to prepare a program for the desired computation, each of these tasks has been written as a function in the C language. The k + 1 functions are labeled TO(), T10),..., Tk(). Each function requires T time units to execute. Due to data dependencies, functions T1() to Tk() must be executed after function To(). There are no data dependencies among the functions T1() to Tk()- (a) Using the given functions, write a C program that executes on a single processor. (b)Write an equivalent C program that executes on k processors. (c) Derive an expression for the ideal speedup for the program in part (b) relative to the program in part (a).
