Hi there, I just uploaded a new version of Join library into Vault under "Concurrent Programming". Could a review be arranged? A brief description: "Join is an asynchronous, message based C++ concurrency library based on join calculus. It is applicable both to multi-threaded applications and to the orchestration of asynchronous, event-based applications. It follows Comega's design and implementation and builds with Boost facilities. It provides a high level concurrency API with asynchronous methods, synchronous methods, and chords which are "join-patterns" defining the synchronization, asynchrony, and concurrency." This update includes code cleanup and exploring using Join for dynamic flow based programming. project website: http://channel.sourceforge.net doc: http://channel.sourceforge.net/boost_join/libs/join/doc/boost_join_design.ht... download: http://sourceforge.net/project/showfiles.php?group_id=157583 Thanks Yigong
