Tier 3 (T3) resources play an essential role in the success of the U.S. CMS physics program by providing critical CPU and storage to meet the needs for the final stages of analysis. T3 computing is used for ntuple production, histogram creation, fitting, limit setting, and other similar activities that are necessary to complete a physics analysis. These sorts of activities rely on a flexible and interactive computing environment, and ensuring sufficient resources are available to U.S. CMS institutions is essential for guaranteeing that U.S. CMS physicists can continue to push the envelope and play a leading role in CMS physics analysis. Furthermore, U.S. CMS institutions have demonstrated the ability leverage NSF and DOE investments in T3 sites by obtaining additional contributions of funding, hardware, and services from universities.
