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: Mark Grippo Applicant's institution: ANL Applicant's division: EVS Project Name: MHK Project title: Hydrodynamic model development for Cobscook Bay Associated funding: DOE Other Systems: Science: Hydrology Project description: Create high resolution hydrodynamic model for Cobscook Bay Maine Project URL: Requested allocation: 1088640 Q1: 272160 Q2: 272160 Q3: 272160 Q4: 272160 Justification: Our run (with turbines activated) simulated 6 days of tides in 12 days of computer time, i.e., 12 real time days. That comes to 12 days * 24 hours * 360 cores = 103680 core-hours for a 6 day tidal simulation. This is for our marconi cluster at UMaine. The rate is 130680 core.hours / (6 days*24 hours*360 cores) = 2 core-hours per 1 hour of tides simulated per core. For the Fusion cluster, we have 800 nodes at roughly the same cpu speed and available memory. So, the rate is 103680 core.hours /( 6 days*24 hours*800 cores ) = 0.9 core-hour per 1 hour of tides simulated per core. We expect to do 7 simulations. 5 simulations of experiments (each is 7 days long) 2 simulation of calibration (each is 14 days long) This gives (5 runs * 7 days) +( 2 runs *14 days) = 63 days of tidal simulations = 1512 hours of tidal simulations. That translates to: 0.9 core-hour per 1 hour of tidal simulated per core * 1512 hours of tidal simulation = 1361 core-hours per core. That comes to 1361 core-hours per core *800 cores=1,088,640 core hours. The requester has used undetermined amount hours of their initial startup project. In addition to approving an initial amount, please specify a Category and Subcategory for this project.
