creates a three stage pipeline, with one process for each command (cat, grep, and wc) These examples and the assembly line analogy have several aspects in common All involve applying a sequence of operations (in the assembly line case it is installing the engine, installing the windshield, etc) to each element in a sequence of data elements (in the assembly line, the cars) Although there may be ordering constraints on the operations on a single data element (for example, it might be necessary to install the engine before installing the hood), it is possible to perform different operations on different data elements simultaneously (for example, one can install the engine on one car while installing the hood on another) The possibility of simultaneously performing different operations on different data elements is the potential concurrency this pattern exploits In terms of the analysis described in the Finding Concurrency patterns, each task consists of repeatedly applying an operation to a data element (analogous to an assembly line worker installing a component), and the dependencies among tasks are ordering constraints enforcing the order in which operations must be performed on each data element (analogous to installing the engine before the hood) Forces

A good solution should make it simple to express the ordering constraints The ordering constraints in this problem are simple and regular and lend themselves to being expressed in terms of data flowing through a pipeline The target platform can include special purpose hardware that can perform some of the desired operations In some applications, future additions, modifications, or reordering of the stages in the pipeline are expected In some applications, occasional items in the input sequence can contain errors that prevent their processing

Solution The key idea of this pattern is captured by the assembly line analogy, namely that the potential concurrency can be exploited by assigning each operation (stage of the pipeline) to a different worker and having them work simultaneously, with the data elements passing from one worker to the next as operations are completed In parallel programming terms, the idea is to assign each task (stage of the pipeline) to a UE and provide a mechanism whereby each stage of the pipeline can send data elements to the next stage This strategy is probably the most straightforward way to deal with this type of ordering constraints It allows the application to take advantage of special purpose hardware by appropriate mapping of pipeline stages to PEs and provides a reasonable mechanism for handling errors, described later It also is likely to yield a modular design that can later be extended or modified Before going further, it may help to illustrate how the pipeline is supposed to operate Let Ci represent a multistep computation on data element i Ci(j) is the jth step of the computation The idea is to map computation steps to pipeline stages so that each stage of the pipeline computes one step Initially, the first stage of the pipeline performs C1(1) After that completes, the second stage of the pipeline receives the first data item and computes C1(2) while the first stage computes the first step of the second item, C2(1) Next, the third stage computes C1(3), while the second stage computes C2(2) and the first stage C3(1) Fig 424 illustrates how this works for a pipeline consisting of four stages Notice that concurrency is initially limited and some resources remain idle until all the stages are occupied with useful work This is referred to as filling the pipeline At the end of the computation (draining the pipeline), again there is limited concurrency and idle resources as the final item works its way through the pipeline We want the time spent filling or draining the pipeline to be small compared to the total time of the computation This will be the case if the number of stages is small compared to the number of items to be processed Notice also that overall throughput/efficiency is maximized if the time taken to process a data element is roughly the same for each stage
