Southern California Earthquake Center SCEC SEISM2 Proposal SCEC’s SI2-SSI: Community Software for Extreme-Scale Computing in Earthquake System Science (SEISM2) Project will push validated simulation capabilities to higher seismic frequencies by addressing scientific problems that limit the accuracy and scale in current numerical representations of earthquake processes. Project software development will address three main computational requirements: (1)Extend earthquake simulations to higher seismic frequencies. (2)Validate simulations against existing earthquake data and empirical GMPEs. (3) Decrease the time-to-solution of SEISM simulations and physics-based seismic hazard models.

Southern California Earthquake Center SCEC SEISM2 Award Details Name: SI2-SSI: Community Software for Extreme-Scale Computing in Earthquake System Science (ACI ) Division of Advanced Cyberinfrastructure Programs (ACI) Software Infrastructure for Sustained Innovation - SSE & SSI (SI2 - SSE&SSI) II. PROGRAM DESCRIPTION The goal of the SI2 program is to create a software ecosystem that scales from individual or small groups of software innovators to large hubs of software excellence. The program includes three classes of awards: 1. Scientific Software Elements (SSE) 2. Scientific Software Integration (SSI) 3. Scientific Software Innovation Institutes (S2I2) -> co-Design?

Southern California Earthquake Center SEISM2 Project Milestones Timeline, Milestones, and Responsibilities. In our revised workplan, we define 14 (was 17) milestones (M1-M14) over the course of the 3-year project. The milestones for each of the three project objectives O1-O3 track a 4-step iterative process for SSE development: improve, evaluate, release, and apply. Each milestone requires the re-integration of one or more SEISM platforms. Year 1:M1: AWP-ODC released with near fault plasticity (O1) M2: Hercules released with frequency-dependent attenuation (O1) M3: Simulations validated against historic events using using SWUS procedures (O2) M4: CyberShake 1Hz Los Angeles hazard model (O1) Year 2:M5: Integrate SEISM-IO Library into AWP for checkpointing (O3) M6: Hercules released with nonlinear plastic yielding (O1) M7: Prototype of parallel discontinuous mesh AWP-DM (O3) M8: Simulations validated against historic events using GMSV SDoF Procedures (O2) M9: CyberShake 1.5Hz LA hazard model (O1) Year 3:M10: Parallelization and optimization of discontinuous mesh AWP-DM (O3) M11: CyberShake SGT data used by Broadband platform (O1) M12: High-complexity ShakeOut simulation (O3) M13: AWP-ODC ported onto MIC (O3) M14: CyberShake EKS hazard model (O1) The project scientists responsible for O1 (physics) are Jordan, Olsen, and Bielak; for O2 (validation) Taborda, Goulet, and Olsen; and for O3 (performance) Cui and Maechling.

Southern California Earthquake Center SCEC Blue Waters Project Extending the Spatiotemporal Scales of Physics-based Seismic Hazard Analysis (OCI ) large-scale simulation targeted at three primary objectives: O1. Validation of high-frequency simulations (up to 8 Hz) against seismic recordings of historical earthquakes, such as the 1994 Northridge earthquake (M 6.7). O2. Computation of 2-Hz CyberShake hazard model for the Los Angeles region as input to the development of high-resolution urban seismic hazard maps by the USGS and SCEC. O3. High-frequency (4 Hz) simulation of a M7.8 earthquake on the San Andreas fault that will revise the 2008 Great California ShakeOut scenario and improve the risk analysis developed in detail for this Scenario

Southern California Earthquake Center SEISM2 Year 1 Project Milestones Milestones for Next Year’s SCEC Annual Meeting 2016: M1: AWP-ODC released with near fault plasticity (O1) M2: Hercules released with frequency-dependent attenuation (O1) M3: Simulations validated against historic events using using SWUS procedures (O2) M4: CyberShake 1Hz Los Angeles hazard model (O1) The project scientists responsible for O1 (physics) are Jordan, Olsen, and Bielak; for O2 (validation) Taborda, Goulet, and Olsen; and for O3 (performance) Cui and Maechling.

Southern California Earthquake Center SEISM2 Project Logistics: Public Interface: Wiki Site with Links to Relevants Results Project Interfaces: Login-required web site access Project subscription list Quarterly group status calls for all funded groups Project objectives for Y1 are consistent with ongoing High-F, CyberShake, and Broadband, Blue Waters PRAC activities. Project participants are asked to contribute to project NSF reports. Project participants are asked to contribute to HPC allocations and to report accomplishments using allocations. Science Goals: SEISM2 software will support the computational requirements of SCEC projects including High-F, BBP, CyberShake, Ground Motion Simulation Validation (GMSV), and Committee for Utilization of Ground Motion Simulations (UGMS) Sustainable Scientific Software Goals: SCEC has special, valuable, expertise in scientific software and should encourage computer skills in sciencies, software projects in NSF, ongoing training for staff. Consistent with SI2 program goals, our SEISM2 project will continue to improve our practices and processes for converting research code into community codes.
