Comparison between task parallelism and data parallelism.

Task parallelism	Data parallelism
It is a form of parallelization of computer code across multiple processors in parallel computing environments [22].	It is a form of parallelization of computing across multiple processors in parallel computing environments [23].
Task parallelism focuses on distributing execution processes (threads) across different parallel computing nodes [23].	Data parallelism focuses on distributing the data across different parallel computing nodes.
