> Hi all,
> The review of Boost.Fiber by Oliver Kowalke is scheduled from Monday, January
> 6th to January 12th.
> -----------------------------------------------------
> About the library:
> Boost.Fiber provides a framework for micro-/userland-threads (fibers)
> scheduled cooperatively. The API contains classes and functions to manage
> and synchronize fibers similar to Boost.Thread. Each fiber has its own
> stack.
> A fiber can save the current execution state, including all registers and
> CPU flags, the instruction pointer, and the stack pointer and later restore
> this state. The idea is to have multiple execution paths running on a
> single thread using a sort of cooperative scheduling (versus threads, which
> are preemptively scheduled). The running fiber decides explicitly when it
> should yield to allow another fiber to run (context switching). Boost.Fiberinternally uses coroutines from
> Boost.Coroutine <>;
> the classes in this library manage, schedule and, when needed, synchronize
> those coroutines. A context switch between threads usually costs thousands
> of CPU cycles on x86, compared to a fiber switch with a few hundred cycles.
> A fiber can only run on a single thread at any point in time.

> - Are you knowledgeable about the problem domain?

the documentation is now available at too (no popup-windows)
