This PR is to mitigate the regression reported in https://github.com/tikv/tikv/issues/7122 by changing the strategy of `pop`. It is found that CPU is mostly wasted in stealing other workers. The situation...
Both async-std and tokio support spawning blocking, which is essential to support IO operations ATM before IO uring is widely supported.
Hello! I recently made crate named `async-executor` that makes it quite easy to create custom executors with almost arbitrary task scheduling strategies. Sharing this here because I thought you mind...
## Problem Currently the maximum level 0 chance is 0.98. Sometimes we still fail to achieve our target even with this maximum value. For example, if we have plenty of...
