Questions tagged [fiber]

Fibers are particularly lightweight threads of execution which use co-operative multitasking.

In computer science, a fiber is a particularly lightweight thread of execution..

Like threads, fibers share address space. However, fibers use co-operative multitasking while threads use pre-emptive multitasking. Threads often depend on the kernel's thread scheduler to preempt a busy thread and resume another thread; fibers yield themselves to run another fiber while executing. The article on threads contains more on the distinction between threads and fibers.

Fibers can be considered as implementation of coroutines so you might like to check also [coroutine] tag.

With Boost.Fiber does c++ come one step closer to Erlang style process/threads?

I am reading http://olk.github.io/libs/fiber/doc/html/ It seems to me that with Boost.Fiber C++ is coming closer to Erlang's ability to have thousands of "processes", also known as "green processes[threads]"…

Is there a fiber api in .net?

Out of more curiosity than anything I've been looking for a set of C#/.net classes to support fibers/co-routines (the win32 version) and haven't had any luck. Does anybody know of such a beast?

Lightweight, portable C++ fibers, MIT license

I would like to get ahold of a lightweight, portable fiber lib with MIT license (or looser). Boost.Coroutine does not qualify (not lightweight), neither do Portable Coroutine Library nor Kent C++CSP (both GPL). Edit: could you help me find one? :)

What are Erlang processes behind the scenes?

I've got very limited knowledge about Erlang, but as far as I understand, it can spawn "processes" with a very low cost. So I wonder, what are those "processes" behind the scenes? Are they Fibers? Threads? Continuations?

Fibers in C#: are they faster than iterators, and have people used them?

So I was chatting with a colleague about fibers and turned up this paper from 2003 that describes a implementation of coroutines in C# using the Fiber API. The implementation of Yield in this paper was for .NET 1.1, so it predates the yield return…
