libco is a C++ coroutine library and user-space task orchestrator designed for cooperative multitasking and high-concurrency execution. It functions as a high-concurrency network framework and a synchronous-to-asynchronous wrapper that allows blocking system calls and socket functions to run asynchronously without modifying existing business logic. The project utilizes a specialized stack-copying context switching model to support millions of simultaneous TCP connections on a single machine. It includes a high-performance time wheel scheduler for managing asynchronous background jobs and dela

Gevent is a Python coroutine concurrency library and asynchronous task manager designed for high-concurrency I/O tasks. It provides a cooperative networking framework for building asynchronous TCP, UDP, and HTTP servers, as well as a WSGI web server implementation for hosting web applications. The project is distinguished by its standard library monkey-patching tool, which replaces blocking synchronous functions with cooperative versions to enable asynchronous behavior in third-party code. This allows for a cooperative multitasking workflow where the system yields execution during I/O waits t

libaco is a low-level C library for cooperative multitasking that provides a runtime for managing asymmetric coroutines. It functions as an execution context manager and stack memory allocator, allowing a single process to initialize independent execution units with private stacks and perform manual context switching via yield operations. The library distinguishes itself through its memory management and stability features, utilizing read-only guard pages at stack boundaries to trigger hardware faults upon stack overflow. It supports both private stack allocation and shared stack pooling to r
