Note that you are not allowed to change the sum of Euler totient algorithm such that it becomes more efficient.
Ĭoncurrent implementation of the code in listing 1 using threads in Java. So, if the program is executed as follows:, its output should be 3044.
The program should thus compute i = 1 ∑ n φ ( n ) The Java code in listing 1 is a direct sequential implementation of the above specification and is provided as a starting point for your concurrent implementation. It is therefore necessary to establish that their greatest common divisor (gcd) is 1, i.e. The totient function is defined as follows: φ ( n ) = ∣ ∣ Two numbers m and n are said to be relativey prime, if the only integer number that divides them both is 1. The Euler totient function computes the number of integers that are coprime ( ⊥ ) to a given integer n. The project will be an exercise in concurrent programming and will require you to parallelise the computation of sum of Euler totient computations over a range of integer values.
