Computer architecture parallelism

What is an example of parallelism in computer?
For example, a parallel program to play chess might look at all the possible first moves it could make.
Each different first move could be explored by a different processor, to see how the game would continue from that point.
At the end, these results have to be combined to figure out which is the best first move..
What is parallelism and its types?
The definition of parallelism is based on the word “parallel,” which means “to run side by side with.” There are two kinds of parallelism in writing—parallelism as a grammatical principle and parallelism as a literary device..
What is task parallelism in computer architecture?
Task parallelism (also known as function parallelism and control parallelism) is a form of parallelization of computer code across multiple processors in parallel computing environments.
Task parallelism focuses on distributing tasks—concurrently performed by processes or threads—across different processors..
Why build parallel systems?
Scalability of a parallel system is the ability to achieve more performance as processing nodes increase.
A system (hardware + software) whose performance improves after adding more nodes, proportionally to the number of nodes added, is said to be a scalable system..
Why do we need parallel computing?
Benefits of parallel computing.
The advantages of parallel computing are that computers can execute code more efficiently, which can save time and money by sorting through “big data” faster than ever.
Parallel programming can also solve more complex problems, bringing more resources to the table..
Parallel programming languages
These can generally be divided into classes based on the assumptions they make about the underlying memory architecture—shared memory, distributed memory, or shared distributed memory.
Shared memory programming languages communicate by manipulating shared memory variables.
The main motivation for executing program instructions in parallel is to complete the computation faster.
But most programs in existence today are incapable of much improvement through parallelism, because they were written assuming the instructions will be executed in order, one at a time; that is, sequentially.
The principle of parallel computing is using multiple processors in parallel to solve problems more quickly than with a single processor, or with less energy consumption.

Parallel Computer Architecture is the method of organizing all the resources to maximize the performance and the programmability within the limits given by technology and the cost at any instance of time. It adds a new dimension in the development of computer system by using more and more number of processors.

Why Parallel Architecture? ✓ Parallel computer architecture adds a new dimension in the development of computer system by using more and more number ofprocessors. ✓ In principle, performance achieved by utilizing large number of processors is higher than the performance of a single processor at a given point oftime.

Form of parallel computing

Bit-level parallelism is a form of parallel computing based on increasing processor word size.
Increasing the word size reduces the number of instructions the processor must execute in order to perform an operation on variables whose sizes are greater than the length of the word.

Ability of computer instructions to be executed simultaneously with correct results

Instruction-level parallelism (ILP) is the parallel or simultaneous execution of a sequence of instructions in a computer program.
More specifically ILP refers to the average number of instructions run per step of this parallel execution.
