What’s the definition of these two, and what’s the difference between a heterogeneous task

  • 0

What’s the definition of these two, and what’s the difference between a “heterogeneous task” and a “homogeneous task”? When I read the Java Concurrency In Practice book, these two phrases jumped out. In my opinion within the book, it is the task size and handling time of task. But I don’t understand it that well. I’ve googled it, but can’t find the accurate answer. Can anyone help me? Thanks.

    • Homogeneous tasks: group of tasks that are processed in a similar way and take approximately the same amount of time. Example: applying the square function to each element of an array. Pattern: Data-parallelism.
    • Heterogeneous tasks: group of tasks that have no clear logical relation and may execute in various amounts of time. Example: estimating pi in parallel with downloading a web page. Pattern: Task-parallelism.
