Hello, A change in allocation has been requested: Requester: raok (Rao Kotamarthi) Project: Atmos_Chem Title: Process Scale Modeling of Atmospheric Chemistry and Transport Description: We continue to investigate the regional scale climate modeling and data assimilation of aerosols in chemical transport models. The models employed for these studies include (a) WRF-CHEM (b) NRCM and (3) GEOS-CHEM. Each of these models has been ported to the fusion luster and uses to perform calculations by our group. All the codes use a mix of MPI and OpenMP programming models and can scale for as few as 4 nodes to several hundred. The GEOS-CHEM model doesn't scale beyond 32 nodes due to gridding constraints. The NRCM (Nested Regional Scale Climate Model) and the WRF-CHEM models are highly scalable and limited by job turnover times and queue limitations. The project will have approximately 4 members. Current: undetermined amount Justification: Requested: 100000 A specific reason has been given: We have just received funding to support the DOE EERE for a modeling project that uses high resolution models at wind farm scale. We plan to test WRF-MPS and WRF-LES for this project and port these models to Mira /NERSC in the near future This needs to be approved and the final allocation amount decided upon. Thank You, The LCRC Accounts System
