Explain Resource request and allocation graph (RRAG)
Deadlocks can be explained by a directed bipartite graph known as a Resource-Request-Allocation graph (RRAG).A graph G = (V,E) is known as bipartite if V can be decomposed into two disjoint sets V1 and V2 such that every edge in E joins a vertex in V1 to a vertex in V2. Suppose V1 be a set of processes and V2 be a set of resources. As the graph is directed we will consider:
a) An edge (Rj,Pi) that is an assignment edge to mean that resource Rj has been allocated to process Pi
b) An edge (Pi,Rj) that is called a request edge to mean that process Pi has requested resource Rj
A three stage network is realized by using switching matrices of size p x s in stage 1, r x r matrices in stage 2 and s x p matrices in stage 3. Using the Lee's probability graph s
Explain Classification Based On Grain Size This categorization is based on distinguishing the parallelism in a program to be executed on a multiprocessor system. The concept is
Program Level : It is the next level consisting of independent programs for parallelism. Coarse Granularity size is used at this level containing ten thousands of instructions.
