In computer science, a parallel algorithm, as opposed to a traditional serial algorithm, is an algorithm which can do multiple operations in a given time. The general idea to parallelize this sequential algorithm is let all thread find the unique minimum weight perfect matching. Therefore, parallel algorithms are used in sorting. Many sophisticated sequential implementations solving this problem, such as mc21, are available, but for parallel linear solvers where a is typically distributed among several processors, it is desirable to use a matching algorithm that works directly on the distributed matrix to avoid the memory limitations of a single node and that scales.
The main difference between parallel and distributed computing is that parallel computing allows multiple processors to execute tasks simultaneously while distributed computing divides a single task between multiple computers to achieve a common goal a single processor executing one task after the other is not an efficient method in a computer.
