Role of mutex in Fibonacci driver gist There are no shared resources in algorithm of calculating Fibonacci sequence itself, hence no critical section are present in the algorithm. Shared resources are needed when we wish to store "Computed result" to not waste CPU cycle on recomputing the values. There are repeating computation without dynamic programming, For an example, Fib(1) are called twice. We can calculate Fibonacci sequence bottom-up by storing result their result in an array.
