Top 100 Supercomputer Locations

If you want to rank cities, the location of supercomputers may be one factor.  They are expensive to build and maintain and presumably they give some benefit to the surrounding area.  Here is a list of the top 100 supercomputers in the world by nearest big city, computer name, organization, and local city.  Some of the cities are guesses (like anything in Korea is labeled Seoul).  This is similar to the other lists in some ways and different in other, with surprises, like Knoxville TN, and Albuquerque.
