Thread Group

[jaredkeithwhite]

Has anyone worked on a thread group concept for TBB? I know that Boost has a thread group, and they aren't that difficult to implement. Has anyone else implemented one for TBB?

Hi, I think in terms of TBB that would be task_group... Meaning an interface that wraps parallel execution of functions inside tasks. Is that what you'd be interested in seeing in TBB?

[jaredkeithwhite]

What I really want is just a counterparty to boost's thread_group, which allows me to join_all().

There are a couple of instances where I can't use the task concept (namely, when receiving asynchronous IO), and I would like to be able to spawn a few threads and join to them all from my main application thread.

I have not used it myself, but will it looks like the tbb_thread class has a join method.

It does indeed. My suggestion for a thread group is more or less wrapper functionality.

It seems to me, you might also find the method:
void task::wait_for_all();
helpful.

[jaredkeithwhite]

Much appreciated. I will take a look.

Note that I'm not using tasks for my particular problem -- I have to use user threads directly, because this is asynchronous IO that I'm waiting to complete.
