concurrency - 幕后的 Erlang 进程是什么？

Question

我对 Erlang 的了解非常有限，但据我所知，它可以以非常低的成本产生“进程”。

所以我想知道，幕后的那些“过程”是什么？

它们是纤维吗？线程？续集？

Answer 1

另外，来自 Erlang 文档:

Erlang processes are light-weight (grow and shrink dynamically) with small memory footprint, fast to create and terminate and the scheduling overhead is low.

在谈论 Erlang 进程时，它说:

Erlang processes are lightweight threads. They're very cheap to start up and destroy and are very fast to switch between because under the hood they're simply functions. A typical Erlang system running on a modern desktop computer can switch between many tens of thousands such processes. Processes are switched every couple of dozen function calls which makes switches less granular but saves a tremendous amount of time normally wasted on context switching.
