The Materials Project (materialsproject.org) uses supercomputing and informatics to compute and disseminate properties of all known inorganic bulk solid materials. Through web pages and web-powered interfaces, the Materials Project currently makes available over 65,000 compounds and over 43,000 bandstructures as well as an unprecedented number of other data such as elastic tensors. With roughly 15,000 users, it is one of the success stories of the Materials Genome Initiative. To achieve this result, the team has put a great deal of work and thought into the underlying computing and informatics infrastructure. This talk will attempt to describe, in clear and straightforward language without the usual alphabet soup of technology acronyms, the essential aspects of this infrastructure and lessons learned in its implementation. The talk will conclude with a preview of some of the data mining efforts and the "user contributions" framework for integrating experimental and other types of external community data into the core database.
