Difference between data and task parallelism
WebSep 26, 2024 · A task represents an operation that is running or going to run. Using the Task class, you benefit from a state-of-the-art fluent API that is easy to use and offers extreme flexibility. Another benefit of the Task Parallel Library is that when it incorporates multithreading, it uses the thread pool. WebApr 10, 2024 · Each parallel instance of an operator chain will correspond to a task. So in the simple example above, the source, map, and sink can all be chained together and run in a single task. If you deploy this job with a parallelism of two, then there will be two tasks.
