OpenPA: Open Portable Atomics

OpenPA (Open Portable Atomics) is an open source library intended to provide a consistent C API for performing atomic operations on a variety of platforms. The main goal of the project is to enable the portable usage of atomic operations in concurrent software. Developers of client software can worry about implementing and improving their concurrent algorithms instead of fiddling with inline assembly syntax and learning new assembly dialects in order to improve or maintain application portability.
