How can May be used for shared-nothing architecture? about may

[Xudong-Huang]

stackful coroutines are independent to some extend, in theory they can be executed everywhere. The atomics and locks are only tools that designed for state sharing and it totally depends on how custom program coroutines. I don't have too much knowledge about shared-nothing architecture. and don't fully understand the real requirements.

I would like to have some kind of LocalExecuter that has no requirements for either Send or Sync and that performs tasks strictly sequentially. Conditionally, within the framework of one such executor, I could create 10 tasks that generate other tasks, but all these tasks will be performed within the same thread and sequentially. This allows us to get rid of locks and atomics, since we do not have competition for resources.

If this functionality already exists, I'd like to know about it. If such a thing exists, I am ready to write an example for documentation myself.

oh, currently there is no mechanism for coroutine thread affinity. but when work_steal feature is disabled, coroutines would execute in the same thread where they got first executed.
