boost.fiber
Boost.fiber
===========
boost.fiber provides a framework for micro-/userland-threads (fibers) scheduled cooperatively.
The API contains classes and functions to manage and synchronize fibers similiar to boost.thread.
A fiber is able to store 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 (threads are
preemptively scheduled) - the running fiber decides explicitly when it yields to allow another fiber to
run (context switching).
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.
A context switch between threads costs usally thousands of CPU cycles on x86 compared to a fiber switch
with less than 100 cycles. A fiber can only run on a single thread at any point in time.
