Assignment Help:

A system contains 10 units of resource class Ru. The resource requirements of three user processes P1, P2 and P3 are as follows

                                                P1                  P2                P3

Maximum requirements          8                     7                   5

Current allocation                   3                     1                   3

Balance requirements            5                     6                   2

New request made                 1                     0                   0

Using Banker's algorithm, determine if the projected allocation state is safe and whether the request of P1 will be granted or not.

From the specified data: Total_alloc=[7] Total_exist=[10]

The projected allocation state is feasible as the total allocation into this does not exceed the number of resource units of Ru. Because P3 is two units short of its maximum requirement and two unallocated unit exits into the system, therefore P3 can complete. It will release the resources allocated to this, i.e., 5 resources. Here P1 can complete as the number of unallocated units of Ru exceeds the units required to satisfy its maximum requirement then P2 can be finished.

Therefore the processes can complete in the sequence P3, P1, and P2. Therefore projected allocation state is safe thus algorithm will grant the request made through P1.
