What is Parallel Processing?
Historical Background
Key Points
12 points- 1.
Parallel processing divides a task into smaller sub-tasks that can be executed simultaneously.
- 2.
It uses multiple processing units, such as cores in a CPU or processors in a GPU, to perform these sub-tasks.
- 3.
There are different types of parallel processing, including data parallelism (same operation on different data) and task parallelism (different operations on different data).
- 4.
Data parallelism is often used in image processing, where the same filter is applied to different parts of an image at the same time.
