Impact/Purpose:
The primary goals are to: (1) Construct a 400-node PC-based supercomputing cluster supporting Windows and Linux computer operating systems (i.e. SuperMUSE: Supercomputer for Model Uncertainty and Sensitivity Evaluation); (2) Develop platform-independent system software for the management of SuperMUSE and parallelization of EPA models and modeling systems for implementation on SuperMUSE (and other PC-based clusters); (3) Conduct uncertainty and sensitivity analyses of the 3MRA modeling system; (4) Develop advanced algorithmic software for advanced statistical sampling methods, and screening, localized, and global sensitivity analyses; and (5) Provide customer-oriented model applications for probabilistic risk assessment supporting quality assurance in multimedia decision-making.
Description:
Developed by NERL/ERD for the Office of Solid Waste, the enclosed product provides an example uncertainty analysis (UA) and initial process-based sensitivity analysis (SA) of hazardous waste "exit" concentrations for 7 chemicals and metals using the 3MRA Version 1.0 Modeling System. The report was developed for OSW as an interactive, installable electronic report and was crucial to the successful completion of the 2003/2004 SAB review of 3MRA. The electronic form of the report represents a 2 gigabyte hard disk requirement for actual installation on a Windows-based PC. NERL has also made the report available through the web via EPA's Center for Exposure Assessment Modeling (CEAM), located under Multimedia Modeling (http://www.epa.gov/ceampubl/mmedia/3mra/index.htm).
