Hello, A yearly allocation for the LCRC cluster has been requested with the following updated information: Submitter/PI: Stephen Kuhlmann Project Name: Supernova_DES Division: HEP Project title: Supernova analysis and modeling for Dark Energy Survey Associated funding: DOE/Office of Science/High Energy Physics Other Systems: 32 nodes ANL/HEP division, 50% time Science: The Dark Energy Survey is a 5-year DOE project to study cosmology, dark energy, and dark matter. It has just completed it's first year of data collection, and it discovered many hundreds of new supernova explosions in distant galaxies. The key to supernova cosmology is the measurement of the brightness of the explosion. We are determining this brightness using data packages on the LCRC cluster, as well as simulating the explosions. Project description: The project is to define the supernova cosmology uncertainties for the new Dark Energy Survey, using a combination of data analysis and parametric simulations. This project uses three software packages, all of which are compiled and running successfully at LCRC. We do not anticipate needing further packages. The SNCosmo and SNANA packages were compiled by the project members, and the MEEP package was compiled by LCRC support and is a softenv product. The use of these resources led directly to several publications in the past year, as described in the project report. The supernova light-curve fits for the supernova data set from year 1 data take 2K-coreHrs each. The second year data set is already becoming available for analysis and will eventually double this. After analysis, we determine about 10% of the raw data are good supernova candidates. For simulations, we need x10 more statistics than good data candidates to define cosmology uncertainties, using at least 10 different simulation parameters. With these numbers we estimate we need 80K coreHrs per quarter. This project will involve five members of the ANL/HEP DES collaboration.
