There are two basic types of parallel processing; pipeline and partitioning.

Pipeline parallelism

If you ran the example job on a system with at least three processors, the stage reading would start on one processor and start filling a pipeline with the data it had read.

Repartitioning data

In some circumstances you might want to actually repartition your data between stages. This might happen, for example, where you want to group data differently. Say you have initially processed data based on customer last name, but now want to process on data grouped by zip code. You will need to repartition to ensure that all customers sharing the same zip code are in the same group.

Instruction pipe lining is a technique that implements a form of parallelism called instruction-level parallelism within a single processor. It therefore allows faster CPU throughput (the number of instructions that can be executed in a unit of time) than would otherwise be possible at a given clock rate.

Parallelism involves replicated hardware (exploiting space). Pipelining involves re-using hardware optimally based on dataflows (exploiting time).

Paralellism can do two calculations at the same time in separate compute units. Pipelining can do a calculation twice in incremental time over doing it once, using a single set of compute units.

The cycle time of the processor is reduced; increasing the instruction throughput. ... The more pipeline stages a processor has, the more instructions it can process "at once" and the less of a delay there is between completed instructions.

A parallel computer is a set of processors that are able to work cooperatively to solve a computational problem. This definition is broad enough to include parallelsupercomputers that have hundreds or thousands of processors, networks of workstations, multiple-processor workstations, and embedded systems.

parallelism

ˈparəlɛlɪzəm/

noun

1. the state of being parallel or of corresponding in some way.

1. "Greek thinkers who believed in the parallelism of microcosm and macrocosm"

the use of successive verbal constructions in poetry or prose which correspond in grammatical structure, sound, metre, meaning, etc.

plural noun: parallelisms

"parallelism suggests a connection of meaning through an echo of form"

COMPUTING

the use of parallel processing.

"massive parallelism gives neural networks a high degree of fault tolerance"

Piplining is not exactly the best option as piplining is based on the assumption that everything is sequential. For example, when data is to be moved to an accummulator after another instruction before is being executed the 2nd instruction cannot be executed as the accumulator has data from the 1st instruction means that the 2nd instruction would operate with the wrong data. This creates a bubble in the pipline cycle.

From this non pipelined archtectures I believe would still have a future based on the above mentioned issue.

A non-pipeline architecture is inefficient because some CPU components are idle while another module is active during the instruction cycle.

–Instruction unit

•overlap fetch-execute cycle so that multiple instructions are being processed at the same time, each instruction in a different portion of the fetch-execute cycle

–Operation unit

•overlap execution of ALU operations

•only useful if execution takes > 1 cycle

–e.g., floating point operations

Pipelining is a particular form of parallelism. In general, parallelism is simply multiple operations happening at the same time. Pipelining is a particular arrangement of functions so that different portions of an operation flow through a particular set of sub-functions, with the sub-functions happening in parallel.

Parallel computing is the simultaneous execution of the same task (split up and specially adapted) on multiple processors in order to obtain results faster. The idea is based on the fact that the process of solving a problem usually can be divided into smaller tasks, which may be carried out simultaneously with some coordination.

A parallel computing system is a computer with more than one processor for parallel processing. In the past, each processor of a multiprocessing system always came in its own processor packaging, but recently-introduced multicore processors contain multiple logical processors in a single package.

There are many different kinds of parallel computers. They are distinguished by the kind of interconnection between processors (known as "processing elements" or PEs) and memory.

Pipelining is a method of increasing system performance and throughput. It takes advantage of the inherent parallelism in instructions. Instructions are divided into 5 stages : IF, ID, EX, MEM, WB. In pipelining, we try to execute 2 or more instructions at the same time thereby increasing the throughput. For more info on pipelining refer to the following website:

a pipeline is a set of data processing elements connected in series, where the output of one element is the input of the next one. The elements of a pipeline are often executed in parallel or in time-sliced fashion; in that case, some amount of buffer storage is often inserted between elements.

A computer program is, in essence, a stream of instructions executed by a processor. Without instruction-level parallelism, a processor can only issue less than one instruction per clock cycle (IPC < 1). These processors are known as sub scalar processors.
