−	== ~~Project Summary~~ ==	+	== Overview: ==
		+
		+	A key problem of geoinformatics is the systematic integration of seismological and geological
		+	information into unified structural representations (USRs). The goal of this project is to
		+	develop the cyberinfrastructure needed to manage a "USR lifecycle" that can progressively
		+	and efficiently refine 3D Earth models. The lifecycle is initiated by the integration of several
		+	components into a starting model; the starting model is refined by full-3D tomographic inversion
		+	of seismic waveform data; the refined model is validated for its proposed applications and
		+	then disseminated to user communities. This new model becomes the main component of the starting
		+	model for the next lifecycle.
		+	In Phase I, we are developing three high-performance computational systems, a UCVM platform
		+	for synthesizing, comparing, and delivering Earth models and two platforms for full-3D tomography,
		+	based on the SPECFEM3D and AWP-ODC codes for anelastic wave propagation. These codes are being
		+	optimized on CPU-GPU supercomputers and used to derive new global and regional models. Our
		+	global focus is on the 3D mantle structure needed to understand geodynamics. Our regional
		+	focus is on California USRs needed for physics-based seismic hazard analysis.
		+	This proposal requests funding for Phase II, a 16-month project that has four goals: (1)
		+	Accelerate the USR lifecycle by improving the interoperability and I/O capabilities of the
		+	computational platforms. (2) Increase the scale of full-3D tomographic inversions by optimizing
		+	simulation software on heterogeneous CPU-GPU systems and by creating scientific workflows
		+	to automate full 3D tomography. (3) Deliver improved global and regional USRs by adding additional
		+	complexity to the model parameterizations (e.g., anisotropy, attenuation, small-scale stochastic
		+	heterogeneities) and by simplifying community access to these complex USRs. (4) Establish
		+	quantitative methods for evaluating USRs against standardized sets of observations. We specify
		+	milestones marking progress towards each objective; in particular, we will move the global
		+	and regional USRs developed in Phase I through another complete lifecycle by the end of this
		+	16-month project, thereby demonstrating acceleration of the lifecycle.
		+
		+	== Intellectual Merit : ==
		+
		+	The intellectual merit of the proposed work derives from (a) the generality of the USRs we
		+	shall construct, which are capable of representing a broad spectrum of heterogeneity controlled
		+	by a variety of geological processes, from the global scale of mantle dynamics to the small-scale,
		+	near-surface structure of sedimentary basins; (b) the power of our data assimilation approach,
		+	which employs the most advanced forms of full-3D tomography; and (c) the creation of a scientific
		+	workflow for progressive model refinement, which structures the USR lifecycle and accelerates
		+	this lifecycle through the efficient use of high-performance computing.
		+	== Broader Impacts : ==
		+	The broader impacts of this project derive from its potential to provide new information to
		+	a very wide range of user communities, from basic researchers who are investigating the fundamental
		+	problems of lithospheric tectonics and mantle dynamics, to applied scientists and engineers
		+	who are trying to improve the utility of physics-based seismic forecasting and hazard analysis.
		+	Regional USRs with lateral dimensions of hundreds of kilometers will be used to simulate earthquakes,
		+	predict strong ground motions, and provide a physical basis for seismic hazard analysis. Regional
		+	USRs with lateral dimensions of thousands of kilometers will constrain the plate-tectonic
		+	processes of lithospheric creation, deformation, magmatism, and destruction. Global USRs will
		+	image the convective structure of the entire mantle and map its relationship to crustal tectonics
		+	and the geodynamo. Global and regional models will also improve imaging of seismic sources,
		+	including earthquakes and nuclear explosions.
		+	Our education and outreach plan is centered on using challenging scientific problems of
		+	compelling societal importance to engage and train a diverse STEM workforce, beginning at
		+	the undergraduate level and continuing through the post-doc level. Our objectives are to build
		+	interdisciplinary collaborations that can apply petascale technology to the most difficult
		+	problems of solid-Earth science and cross-train diverse groups of undergraduate interns and
		+	early-career scientists in geoscience and computer science.
