This data synchronization library provides read-side access which scales linearly with the number of cores. It does so by allowing multiples copies of a given data structure to live at the same time, and by monitoring the data structure accesses to detect grace periods after which memory reclamation is possible. Changelog: * Version 0.5.0 changes the API presented by memory model, architecture abstraction and data structure primitives in headers. The prefixes are, respectively: - cmm_ : Concurrent Memory Model - caa_ : Concurrent Architecture Abstraction - cds_ : Concurrent Data Structures This will make UST's life easier for instrumentation of large projects like MariaDB and qemu.
