Classification Of Parallel Computers 

Introduction

Parallel computers are those that underline the parallel processing among the operations in some way. In the last unit, all the necessary terms of computation and parallel processing have been defined. Parallel computers can be categorized based on the data and instruction streams forming different types of computer organisations. They can be classified based on the computer structure, e.g. multiple processors having individual  memory or one shared global memory. Parallel processing levels can be defined based on the size of instructions in a program called grain size. Therefore, parallel computers can be classified based on different criteria. This unit discusses all types of classification of parallel computers based on the over mentioned criteria.
