ThreadWeaver
ThreadWeaver is a system library initially developed for KDE Software Compilation 4 and later refactored for KDE Frameworks 5.
ThreadWeaver allows developers to easily take advantage of multi-core processors and multithreading. In ThreadWeaver the workload is divided into individual jobs, then relationship between jobs (what order they should be completed or which has a higher priority); from that ThreadWeaver will work out the most efficient way to execute them. Krita has implemented visual filter previews using ThreadWeaver to prevent GUI lockups.
