The Text
If not planned properly, a distributed system can decrease the overall reliability of computations if the unavailability of a node can cause disruption of the other nodes. In computer science, and more specifically in computability theory and computational complexity theory, a model of computation is a model which describes how an output of a mathematical function is computed given an input. Hybrid Model: To combine the advantages of both the workstation-server and processor-pool models ,a hybrid model may be used to build a distributed computing system. By continuing, I agree that I am at least 13 years old and have read and agree to the. For example, grid computing, studied in the previous section, is a form of distributed computing where the nodes may belong to different administrative domains. A model describes how units of computations, memories, and communications are organized.

MapReduce is a simple programming model for enabling distributed computations, including data processing on very large input datasets, in a highly scalable and fault-tolerant way. In a working environment that has groups of users who often perform jobs needing massive computation,the processor-pool model is more attractive & suitable. Distributed Computing: Principles, Algorithms, and Systems Models of Communication Networks The “causal ordering” model is based on Lamport’s “happens before” relation. Tests & Videos, you can search for the same too. The models of computation generally considered to be distributed are process models, in which computational activity is represented as the con-current execution of sequential processes. Architectural model describes responsibilities distributed between system components and how are these components placed. Lecture slides for the book.

Other models, such as Petri nets [Thi85], are usually not studied under the title of distributed comput-ing, even though they may be used to model spatially distributed systems.
