Introduction to parallel computing

Parallel computing or parallel computing is relative to serial computing. It is an algorithm that can execute multiple instructions at the same time, aiming at improving the calculation speed and solving large and complex calculation problems by expanding the scale of problem solving. The so-called parallel computing can be divided into time parallelism and space parallelism. Time parallelism refers to pipelining technology, and space parallelism refers to multiple processors performing calculations at the same time.
