The Asteroseismic Modeling Portal is a community facility that allows astronomers to derive the fundamental properties of sun-like stars from observations of their natural vibrations. The underlying science code uses a parallel genetic algorithm to match the observations with standard theoretical models of stars. In the first five years of the project, AMP was applied to more than 100 stars observed by NASA's Kepler mission, yielding a uniform set of stellar properties that have been used to study the structure and evolution of stars and their planetary systems. By using the AMP gateway, more than 100 users around world can submit jobs, retrieve results and even analyze the performance of source codes very easily. And during 8 year running, AMP has submitted 30424 jobs and spent 18,795,892 SUs. XSEDE/ECSS objectives include updating OS and related software of the servers, and optimizing parallel performance of AMP 2.0 science code on by TACC staff.
