Hello, A yearly allocation for the LCRC cluster has been requested with the following updated information: Submitter/PI: Mihai Anitescu Project Name: UQCLM Division: MCS Project title: Uncertainty Quantification for Land Model in Climate Science Associated funding: Climate Science for a Sustainable Energy Future; PI: Mihai Anitescu; site PI: Ian Foster Other Systems: Science: In this project we study uncertainty quantification (UQ) methods applied to Community Land Model (CLM). CLM is the land model for the Community Earth System Model (CESM) and the Community Atmosphere Model (CAM). It consists of several sets of large and nonlinear complex systems. We aim to develop intrusive uncertainty quantification methods and to demonstrate their computational advantage over a differentiated version of CLM with automatic differentiation (OpenAD) which will open the way for gradient-based optimization for calibration in land testbed. Project description: Notes: This is a renewal of a proposal that we submitted after July. We request an additional 35K hours to what we had allocated last year. Rationale: We have a deliverable on Oct 31, so we expect to burn a lot of time in October. We need about 20K for development, and the rest for production. Project URL: Current FY Hours Used: undetermined amount New FY Requested allocation: 85000 Q1: 25000 Q2: 15000 Q3: 15000 Q4: 30000 Justification: Thank You, The LCRC Accounts System
