Question

Processes 0,1,2,3,4,5,6 are executing concurrently.
Process 3, 4, 5, and 6 must start their execution after the execution of Process 0, 1,
and 2 ends.
There is no enforcement of order between the executions of Process 3, 4, 5, and 6.
There is no enforcement of order between the executions of Process 0, 1, and 2.
Implement the required synchronization using a minimum number of binary semaphores. Give
the initial values of each semaphore.

Explanation / Answer

Solution:

So initially the value of semaphores a, b, c, and d will be set to 0.

par begin

begin P0: par begin V(a), V(b), V(c), par end, end;

begin: P(a), end;

begin P(b), end;

begin P(c), end;

begin: par begin V(a), V(b), V(c), V(d), par end, end;

par end

In the above given sequence 4 semaphores has been used and that is a minimum number in order to provide synchronization between the processes.

I hope this helps. Don't forget to give a thumbs up if you like this.
