I think we are far from having an optimized queuing, but one successful sequence was 48 nodes/384 cpu, and we had 3 jobs going at the same time with this allocation. Steve Ray asksŠ This project was granted 83K hours per quarter (332 total) for FY14. It appears that they want to add 200K for the 2nd half. Should we add 100K now for Q3 and then take the rest to the Committee in March? Ray

Hello,

A change in allocation has been requested:

Requester: kuhlmann (Stephen Kuhlmann) Project: Supernova_DES Title: Supernova modeling and analysis for Dark Energy Survey 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.

Current: undetermined amount Justification:

Requested: 200000

A specific reason has been given: The previous 166K hours on fusion have been well used. The results form the basis of a presentation at the most prestigious astronomy conference next week in Washington DC. In addition, we upgraded our software to use MPI and most of the previous allocation was used efficiently. We have learned a lot from the previous results and are preparing a new set of supernova simulations and analysis that require a new allocation of comparable size.

This needs to be approved and the final allocation amount decided upon.

Thank You, The LCRC Accounts System _______________________________________________ allocations-admins mailing list [email protected] https://lists.lcrc.anl.gov/mailman/listinfo/allocations-admins
