Threading/Concurrency vs Parallelism

• nailer 18y ago
  "If on a single core machine you are using threads and it makes perfect sense for your scenario, then you are not 'doing parallelism', you are just doing multithreading." Er, yes. We know that. However the only single core machines you can buy these days are Netbooks. Big title, little story.

    And if your netbook has an intel Atom processor; it has hyperthreading and presents itself to the operating system as two cpus.

    nailer: Thanks for the feedback. Is that the point you took away or did you skip reading the rest of the article? The context of that quote is not about single core versus multi core. It is about the intent of your code. It is a quick rule of thumb. For example, keeping the UI responsive is a goal you have regardless of the cores of the machine. To deliver on that goal you can use threads (multithreading) but that would not be equal to parallelism. The larger point here is the difference between the term multithreading and parallelism. Post back on my blog post if you have any questions or suggestions on making that clearer.
