		+	COMMUNITY COMPUTATIONAL PLATFORMS FOR DEVELOPING THREE-DIMENSIONAL MODELS OF EARTH STRUCTURE
		+	Project lead: Thomas Jordan, University of Southern California
		+	Yellowstone allocation: 7.3 million core-hours
		+
		+	Precise information about the structure of the solid Earth comes from seismograms recorded at the surface of a highly heterogeneous lithosphere. Full-3D tomography based on adjoint methods can assimilate this information into three-dimensional models of elastic and anelastic structure. These methods fully account for the physics of wave excitation, propagation, and interaction by numerically solving the inhomogeneous equations of motion for a heterogeneous anelastic solid. Full-3D tomography using adjoint methods requires the execution of complex computational procedures that challenge the most advanced high-performance computing (HPC) systems. In this allocation, we request computational resources to migrate and run two tomographic platforms onto NWSC systems. The two computational systems we propose to port to NWSC include the AWP-ODC 4th-order, staggered-grid, finite-difference code, which has been widely used for regional earthquake simulation and physics-based seismic hazard analysis, and the SPECFEM3D spectral element code, which is capable of modeling wave propagation through aspherical structures of essentially arbitrary complexity on scales ranging from local to global. We will use these tomographic computational tools to refine Community Velocity Models (CVMs) using earthquake waveforms and ambient-noise Green functions, and to investigate the iterative convergence of the tomographic models from disparate starting models. The resulting improved regional and global 3D models will provide better images of mantle convection and its relationship to crustal tectonics and the geodynamo; will more precisely constrain the plate-tectonic processes of lithospheric creation, deformation, magmatism, and destruction; and will improve imaging of seismic sources, including damaging earthquakes and nuclear explosions.

 The ASD call for proposals (https://www2.cisl.ucar.edu/docs/allocations/asd) noted several key deadlines for benchmarks and reports. These deadlines are in place to ensure that ASD teams are engaged and ready to take advantage of Yellowstone as soon as it is available. As stated in the call, "If a project is unable to meet these benchmark and production deadlines and guidelines, the ASD allocation will be reduced to 10% of the original allocation, and CISL will reallocate the resources."

		+
		+	ASD project leads and technical leads,
		+
		+	Congratulations on your Accelerated Scientific Discovery (ASD) project and being one of the first projects with a chance to showcase the capabilities of Yellowstone and its potential for scientific impact! (Project leads should have received the official award letter on Friday.)
		+
		+	Now the work begins.
		+
		+	This message covers a number of logistical topics and will help ensure that CISL and the ASD teams are on the same page regarding schedule, deadlines, support, and system access, and to make sure all projects have the best chance at success.
		+
		+	As explained below, you will be receiving information on user accounts, support contacts, and system access from various channels. Please read this message carefully; it describes your responsibilities as well as what you can expect from CISL.
		+
		+	For general ASD questions, please don't hesitate to contact me, but otherwise please work directly with your designated support contacts, who will be contacting you soon, (or cislhelp@ucar.edu) from this point on.
		+
		+	Best regards,
		+
		+	Dave

		+	Manager, User Services Section, Computational & Information Systems Laboratory
		+	National Center for Atmospheric Research, PO Box 3000, Boulder CO 80307-3000
		+
		+
		+	SYSTEM ACCESS: JANUS, JELLYSTONE, AND YELLOWSTONE
		+
		+	To prepare for Yellowstone access, we will provide access to the Janus cluster at CU-Boulder for the purposes of porting, compiling, testing, and benchmarking of codes to be used. Next, once the Yellowstone test system is available -- it's named "Jellystone" and comprises 32 16-core nodes -- we will give your team access to this system to port and test codes on Yellowstone-equivalent hardware.
		+
		+	For these first two systems, we will provide user accounts for the project's technical leads and any additional team members that you identify. To minimize unnecessary accounts, we ask that you limit Janus and Jellystone account requests to users essential to running the HPC jobs on Yellowstone.
		+
		+	Project leads or technical leads can send user account requests to cislhelp@ucar.edu. (Please see LOGINS AND ACCOUNTS at the end of this message.)
		+
		+	Once the Yellowstone system has passed acceptance, we will be happy to add user accounts for additional team members.
		+
		+
		+	PROJECT CODES
		+
		+	On Janus, all ASD teams will share a common project code that has been established for this purpose: "NCAR46660123". Please communicate with your designated consultant before submitting any very large jobs.
		+
		+	As Yellowstone and its new accounting system become available, each ASD team will be given a unique project code for use on that system. Jellystone may use this code or may not require a project code.
		+
		+
		+	CONSULTING AND VISUALIZATION SUPPORT
		+
		+	Each ASD project will be assigned a consultant from CISL's Consulting Services Group (CSG) and a CISL visualization expert. These persons will contact the technical lead within the next week to introduce themselves and help begin work on Janus.
		+
		+	Please feel free to contact these individuals directly (no need to work through me!) or you can always contact cislhelp@ucar.edu (303-497-2400). Be sure to mention your ASD involvement and help requests will get to your designated point(s) of contact.
		+
		+
		+	ASD DEADLINES AND SCHEDULE
		+
		+	The ASD call for proposals (https://www2.cisl.ucar.edu/docs/allocations/asd) noted several key deadlines for benchmarks and reports. These deadlines are in place to ensure that ASD teams are engaged and ready to take advantage of Yellowstone as soon as it is available. As stated in the call, "If a project is unable to meet these benchmark and production deadlines and guidelines, the ASD allocation will be reduced to 10% of the original allocation, and CISL will reallocate the resources."
		+
		+	-- Preliminary benchmark: June 29, 2012. On Janus or Jellystone (if available).
		+
		+	-- Yellowstone benchmark: July 31, 2012 (or no later than 10 days after Yellowstone acceptance).
		+
		+	-- Primary HPC runs: August 2012 - October 2012. To accommodate all meritorious ASD requests, university ASD projects will be able to complete some of their runs in November 2012. Please note: You will be running alongside the entire Yellowstone community in October and November and should plan your HPC runs accordingly.
		+
		+	-- NWSC GRAND OPENING: October 14-15, 2012. NCAR and the University of Wyoming are planning the NWSC Grand Opening for mid-October. The director of NSF, the governor of Wyoming, and other dignitaries will be in attendance. CISL would like to showcase the early accomplishments of the ASD program at that time. Please work with your designated consultant, visualization expert, and CISL's communications specialist (Marijke Unger) to plan runs, prepare visualizations, and briefly describe your projects in time for this event and the surrounding publicity. (This work will satisfy the preliminary reporting requirement.)
		+
		+	-- Preliminary report: November 5, 2012. You may choose to provide additional details beyond the materials requested for the NWSC Grand Opening.
		+
		+	-- Geyser/Caldera, GLADE access: August 2012 - June 2013. ASD projects will continue to have access to the Geyser and Caldera clusters, as well as their GLADE project spaces for data analysis and visualization through June 30, 2013.
		+
		+	-- FINAL REPORT: July 1, 2013. The final report should be up to five pages describing the research results, the computational experiments performed, the code efficiency, and listing the scientific papers in preparation, submitted, or published as a result of the ASD computations.
		+
		+	-- HPSS access: November 2013. CISL will allow ASD projects to keep data for one year after the end of the ASD period on the HPC system. After that point, projects should plan to make arrangements for there data or discuss other options with CISL.
		+
		+	(Should the Yellowstone installation schedule change significantly, we will notify you of any changes to these deadlines.)
		+
		+
		+	ACKNOWLEDGING CISL AND YELLOWSTONE
		+
		+	ASD projects are required to acknowledge CISL and Yellowstone support for the provision of computational resources in all resulting publications. Please see https://www2.cisl.ucar.edu/docs/acknowledging-ncarcisl.
		+
		+	* Such acknowledgments are a requirement for participation in any future Accelerated Scientific Discovery opportunities. *
		+
		+
		+	LOGINS AND PASSWORDS
		+
		+	If you currently have or previously had CISL user accounts, your login and token will be unchanged.
		+
		+	If you do not have a CISL account, you will receive a YubiKey via FedEx. Instructions will be emailed to new users. We require you to return all access tokens to us when your CISL use ends. Otherwise, there will be a charge of $15 per YubiKey (or $67 per previously issued CRYPTOCard).
		+
		+	Users may not share passwords or accounts on NCAR/CISL computers. Project leads or technical leads may send account requests for additional users to cislhelp@ucar.edu. Please include full contact information, including a shipping address for the YubiKey.
