I have a C++ development project for which tbb::flow seems to be an ideal library or framework to use. But outside of Intel articles and papers I have not seen much or any usage of tbb::flow. This only bothers me because if tbb::flow is a good as it seems to be when reading about it, I would expect it to be more widely used or at least used a few projects. That I cannot find more/any usage of tbb::flow makes me worried. Is there something wrong with tbb::flow that projects do not use it? Is there some alternative that is more popular? (Not necessarily better but more popular?)
So my question is: what are good example projects that use tbb::flow? Please note that I am not trying to criticize tbb::flow or start an argument. I am just trying to find out where tbb::flow is used, so I can make a more informed decision about whether I should use tbb::flow.
