Question

Using a resource allocation graph, show the possibility of a deadlock in this implementation.

 

Modify the order of some of the get requests to prevent the possibility of any deadlock.

 

Is it possible that a resource deadlock involves multiple units of one type and a single unit of another? If so, give an example.

Resource allocation graph- concurrency In the code below, three processes are competing for six resources labelled A to F. void P1() { Void P2() | void P0() |{ while ( true) { { while(true) { While(true){ get (A); get(D); get(C); get (B); get(E); get(F); get (C); get(B); get(D); Ilcritical region llcritical region llcritical region Iluse A,B,C I/ use D, E, B I/ use C, F, D release(A); release (D); release (C); release(B); release (E); release (F); release(C); release (B); release (D): } } } } } }
