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:
Explain the basic performance equation Ans: The basic performance equation is following T = N * S/ R T => It is processor time required to execute a program N => act
Message passing is possible the most widely used parallel programming paradigm these days. It is the most portable, natural and efficient scheme for distributed memory systems. It
In computing, virtual memory is a memory management method developed for multitasking kernels. This technique virtualizes computer architecture's various forms of computer data sto
What is partition? Partitions divide a system into several independent or weakly coupled subsystems, each giving one kind of service. Partitions use peer-peer subsystems.
Q. What are the types of Instructions? Computer instructions are translation of high level language code to machine level language programs. So from this point of view machine
Contraposition : The contraposition equivalence is as follows: So it may seem a small strange at first, this means that it appears which we have said nothing in the f
what is depth buffer algorithm?
In order to concatenate strings only for output purposes which command can be used in conjunction with the 'Write' statement. NO-GAP command.
Q. Describe buffer of receiving process? MPI_Gather (Sendaddr, Scount, Sdatatype, Receiveaddr, Rcount, Rdatatype,Rank, Comm): 'Using this function process with rank' rank
a) Prototype a macro known AP which takes 4 integer parameters n (number of terms), a (first term), l (last term) and Sum (sum of n terms), provided that: Sum = (a+l)*n/2 b)
