Presented on July 14, 2013 at the annual KDE Akademy conference: ThreadWeaver is the concurrency scheduler framework in KDE. It provides a high-level multi-threading API convenient for application programming, combined with powerful features like aggregate tasks, task dependencies and queue policies. With the dawn of KDE Frameworks, ThreadWeaver has been refactored, extensively tested, benchmarked and generally polished. This presentation will introduce the audience to ThreadWeaver programming and central concepts, explain the (few) changes and additions in the API in KDE Frameworks, and show some performance benchmarking results.
