Proposed Timeline for CME Milestones

The SCEC Community Modeling Environment will be developed by collaborative efforts between the SCEC institutions and ISI, SDSC, IRIS, and USGS. The research and development tasks will be supported by teams consisting nominally of supervisory staff, one or more post docs, and one or more graduate students. The teams will be constructed to ensure the linkage of expertise in information technology and geoscience, with supervisory staff in geoscience provided by SCEC, USGS, and IRIS, and supervisory staff in computer science provided by ISI and SDSC.

Geophysics activities will be supervised by primarily by senior scientists from the Scripps Institution of Oceanography, Carnegie Mellon University, University of California at Santa Barbara, University of Southern California, and San Diego State University. However, we expect many other geoscientists to be involved through their participation in SCEC research, which will be tightly coordinated with this project. Activities associated with knowledge-based collection management will be centered at the San Diego Supercomputer Center, while Grid, knowledge-base and knowledge-acquisition activities will be centered at the Information Sciences Institute. Integration activities will be the responsibility of all participants, but they will be coordinated by the P.I. and the SCEC Information Architect, who will act as Project Manager.

Each year of this five-year project will have an overarching goal and a series of specific objectives, listed below. For the purpose of indicating the division of task responsibilities, the efforts of USGS personnel, who will participate at no cost to this project (and are thus not in our budget), are not listed separately, but rather combined as part of SCEC.
