Hi All
I am building OpenCV from source to get every bit of performance out of it. So in the process of doing that I see that if I choose "TBB" the "Concurrency" gets automatically disabled.
I like to know which is efficient. Obviously I know its "TBB" but what is "Concurrency" mean here.
Actually TBB option specifies that you will only using the TBB framework for concurrency optimization. However, if you select the concurrency option, it will compile the library to be able to use different concurrency frameworks, and while executing code it will automatically detect which frameworks are available on the system and use the appropriate one for you.
More info at the changelogs. Check beneath 2.4.3 where this concurrency is explained at the universal parallel_for_ implementation.
An extra benefit is that you enjoy parallelization without the need of installing TBB on your system, unless you explicitly define it in your cmake options.
Concurrency is parallel framework for Windows developed by Microsoft and distributed with Visual Studio. OpenCV uses common API for concurrent programming. TBB, GDC, Concurrency, etc are its back-ends.
