When to use thread bound filters?

[tims666]

Hi everyone, just joined the forum.
I'm new to parallel programming, and I have what is hopefully a simple question:
What are thread bound filters useful for? I got an inkling that they are mainly for interfacing with other threading solutions? But was wondering if say, tying an I/O filter to one thread might improve I/O speed at all?

Thanks!
Tim.

My current understanding is that, if you have to ask, a bound filter is not for you, i.e., it only has very specialised uses.

The intended usage of thread bound filters is in situations where execution of a filter depends on some context that is hard or impossible toset up in TBB worker threads (or to transfer there). But I believe our creative users will find out some other scenarios to apply thread bound filters for good :)
