Multiple Copies of the Same Task

Multiple Copies of the Same Task

An easy way to complete more work is to employ multiple copies of the same task. Each individual task will take the same time to complete, but because multiple tasks are completed in parallel, the throughput of the system will increase.

This is a very common strategy. For example, one system might be running multiple copies of a rendering application in order to render multiple animations. Each applica-tion is independent and requires no synchronization with any other.

Figure 3.17 shows this situation, with a single system running three copies of task A.

Once again, the performance of the system is an increase in throughput, not an improvement in the rate at which work is completed.
