Professor Kristin Persson from UC Berkeley give a very interesting talk on her groups efforts to build a materials properties database using the quantum mechanical codes on the high performance super computers at Lawrence Berkeley National Laboratory. There are about 70,000 inorganic compounds but there is only materials properties on only about 300-400 compounds. It took about a year to get the code to run on the super computer that would work well with the work flow of the user community. It the last 2 years, the project has generated 10 time the data that was previously available. The Materials Project database is open source and open access.
