LOCKIN is a new locking library that includes more than 10 state-of-the-art lock algorithms. For simplicity, LOCKIN offers these algorithms in C header files, so that selecting the algorithm to use can be as simple as setting one configuration flag. LOCKIN can be also set to overload the default pthread mutex lock interface, in order to allow for easily modifying locks in pthread-based systems.

Most importantly, LOCKIN includes MUTEXEE, our optimized version of pthread mutex algorithm. MUTEXEE delivers significant performance and energy efficiency benefits over mutex.
