ThreadWeaver is a programming library developed for KDE 4 by Mirko Boehm that allows developers to easily take advantage of multicore processors. 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.
