Consider the resource allocation graph shown in Figure 1:

P2 R3 P3 P1 R2 PA

Figure 1: Processes and resources allocation graph:

  • Assume all processes makes no further requests. Is the current system state is deadlocked or not? Explain? 
  • If P2 requests one unit of R3, Is the resulting system state is deadlocked or not? Explain.    
  • If P3 requests one more unit of R1 and P2 requests one unit of R2, Is the resulting system state is deadlocked or not? Explain.
