There are many tools for OpenMP benchmarking which measure the various aspects of the performance, such as the overheads of OpenMP directives and the characteristics of the whole system. But we lack some tools to show us the worksharing details when the OpenMP program finished running. The OMPit (OMPi for tutoring) is designed to provide the worksharing information during the running, which can be used for tutoring and might help debugging or tuning. The work-sharing logging includes the work assignment and the timestamps for three different work-sharing behaviors. The logging information can be output as a text files or visualized figures. The designing of OMPit is provided and the details of how to inserting the logging code into the OMPi compiler is discussed too.
