How can deadlocks be represented?

Deadlocks are able to be described in terms of a directed graph called as a system resource-allocation graph. This graph contains of the following:

  • a set of vertices V
  • a set of edges E
  • The set of vertices V is partitioned in to dissimilar types of nodes = {p1, p2...} the set of active process in the system, and R= {r1, r2...} the set of resource in the system.

Pi      Rj indicates that process pi has requested an instance of resource type Rj and is waiting currently for the resource. This is called as the request edge.

 Rj      Pi indicates that an instance of resource Rj has been allocated to process Pi. This is called as the assignment edge.
