Hello,

A new project on the LCRC cluster has been requested. Please forward the information on to the LCRC Allocation sub-committee.

Applicant's name: Stephen Kuhlmann Applicant's institution: ANL Applicant's division: HEP Project Name: Supernova_DES Project title: Supernova modeling and analysis 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 new 5-year DOE project to study cosmology, dark energy, and dark matter. It will discover thousands of new supernova explosions in distant galaxies. The key to supernova cosmology is the measurement of the absolute brightness of the explosion. We simulate the explosion in a parametric way, and we need to model the full 5-year survey by varying the explosion parameters in a systematic set of simulations. Project description: The project is to define the supernova cosmology uncertainties for the new Dark Energy Survey which will collect thousands of supernova explosions.

This project uses the SNANA simulation package http://sdssdp62.fnal.gov/sdsssn/SNANA-PUBLIC/ as well as the SNCosmo analysis package http://sncosmo.readthedocs.org/en/latest/index.html. Both packages have been compiled on Fusion.

The light-curve fits in SNANA, to a single supernova, takes 30s on a dedicated processor. We need x10 the expected data statistics in our simulations to define uncertainties. The total expected simulation load per quarter is: 50K supernova * 30s * 10 parameters * 20 sets = 83K hours. Each quarter our simulation will be updated due to improved knowledge based on the new data now being recorded.

This project will involve five members of the ANL/HEP DES collaboration.

Project URL: http://www.hep.anl.gov/des/ Requested allocation: 332000 Q1: 83000 Q2: 83000 Q3: 83000 Q4: 83000 Justification:

The requester has used undetermined amount hours of their initial startup project.
