Microsoft Parallel Patterns Library (PPL) vs. OpenMP

I want to compare PPL vs. OpenMP regarding their performance, but can't find a detailed investigation on the web. I believe there are not many people who are experienced with PPL.

I'm developing my software on Windows, using Visual Studio 2010, and don't want to port it to somewhere else in a short term.

If portability is not an issue, and only concern is the performance, what do you think about these two methods?

Solution

  • It probably depends on your algorithm, however this research indicates that PPL may be faster then OpenMP:

    Serial : 72ms
OpenMP : 16ms
PPL    : 12ms
