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 to recognize the subtasks or instructions in a program which can be executed in parallel. E.g. there are three statements in a program and statements S1 and S2 can be exchanged. It implies, these are not serial as shown in Figure. Then S1 and S2 are able to be executed in parallel.
Figure: Parallel execution for S1 and S2
However it's not enough to check for parallelism between processes or statements in a program. The decision of parallelism too depends on the subsequent factors:

What is an expression tree? How an expression is evaluated using an expression tree? Algebraic expressions is as given here a/b+(c-d)e That has an inherent tree-like structure
Q. What do you mean by Loader? Loader is a program that assigns absolute addresses to program. These addresses are produced by adding the address from where program is loaded i
Which of following requires refreshing SRAM., DRAM., ROM. or EPROM. ? Ans. DRAM. requires refreshing.
What is the necessity of an interface? Any device that has to be linked to a CPU requires an interface. This takes care of the mismatch in speed, data and electrical character
Q. Executing a parallel algorithm? Multiple processors need synchronization with one another when executing a parallel algorithm. So task which is running on processor X may ha
