This code provides an example of a transactional memory proposal as described in n1613.
You can find the transactional memory implementation in the transaction-impl folder. This folder also contains several .cpp files with usage examples, which can be executed for time measurement.
Another folder, mutex-impl, contains the same classes but implemented with std::mutex for synchronization. This allows for performance comparison between the transactional and mutex-based implementations.
The last folder, test-configuration, includes settings and initial data needed for measurement, such as the number of iterations or the timer class used to calculate the elapsed time.
To build that project you need gcc compiler and libitm installed on you machine. Other compilers haven't support for that proposal.
