+**True parallel processing using native threading and multiprocessing for parallelizing code, *without* blocking.**
 
 This library is a component for [Amp](https://amphp.org) that provides native threading, multiprocessing, process synchronization, shared memory, and task workers. Like other Amp components, this library uses Coroutines built from Awaitables and [Generators](http://www.php.net/manual/en/language.generators.overview.php) to make writing asynchronous code more like writing synchronous code.
