Research Highlight
Using Matrix-free, Multigrid Methods in ASPECT for Large Scale Computations
Solving discrete finite element systems rely heavily on the computation of matrix-vector products with sparse matrices. These matrix-vector products tend to dominate the total amount of work required for the average finite element program, and, as these matrices can be quite large and do not fit into the cache of a modern machine, accessing the data from RAM has become a major bottleneck in finite element computations. Instead of computing the entries of and storing a system matrix, matrix-free methods define an operation on a vector as a loop over the cells in the domain, applying small, dense matrices defined locally on the cell, and summing the results over the entire domain. In this way, one replicates the action of a matrix while never actually storing a matrix. These methods show significant gains in the time of a matrix-vector product as compared to traditional matrix-based methods when using degree 2 and higher finite elements ...

Dear Colleagues,
The first CIG webinar of 2019 will be held next Thursday, November 14 from 2-3 PM Pacific Time.
The webinar will be presented by Dr. Richard Styron (GEM Foundation and Earth Analysis, LCC) on “The Release of the GEM Global Active Faults Database and Global Seismic Hazard Map”:
In late 2018, the Global Earthquake Model Foundation (GEM) released the initial version of several major products relating to seismic hazard and risk, including the Global Seismic Hazard Map, the Global Seismic Risk Map, and the Global Active Faults Database. Though these are intended primarily to support GEM's mission to reduce earthquake risk, they may be of use or interest to geodynamics researchers and the broader Earth science community. The GEM Global Active Faults Database (github.com/GEMScienceTools/gem-global-active-faults) is a dynamic, evolving compilation of active faults worldwide, currently containing ~14,000 fault traces. Associated metadata describe the geometry, kinematics, slip rates and other parameters relevant to seismic hazard analysis. Metadata completeness varies regionally, with ~75% of faults having some slip rate information. The GEM Global Seismic Hazard Map (globalquakemodel.org/gem) displays the geographic distribution of Peak Ground Acceleration with a 10% probability of exceedance in 50 years, and is derived from a mosaic of national or regional seismic hazard models created by a variety of organizations including the GEM Secretariat. Additional topics of collaboration or mutual beneficial research between the geodynamics and seismic hazard communities will be discussed.
To join the webinar, please connect at: https://zoom.us/j/955605274
For additional information, please visit https://geodynamics.org/cig/events/webinars/.
As this webinar may be of interest to the broader Earth Sciences community, we encourage forwarding this announcement on to additional mailing lists or colleagues that may not normally receive CIG announcements.
We look forward to your attendance and please do not hesitate to contact us if you have any questions!
Sincerely,
John Naliboff

IGNITE-Future Faculty Development Program
William and Mary (Williamsburg, VA)
March 22-24, 2020
All expenses paid workshop
https://www.wm.edu/offices/diversity/ignite/index.php
IGNITE provides participants with the opportunity for professional development, and to have candid discussions with department heads, deans, and early career faculty members about life in academia. As a part of the experience, participants will be offered opportunities to tour campus and research facilities, meet with current faculty to gain a greater awareness of research and teaching opportunities, discuss their career prospects and academic work, attend workshops, and present a job talk.
Post-docs and ABD candidates with research interests in sedimentology, stratigraphy, mineralogy, petrology, data science, geoengineering, or geophysics are especially encouraged to apply.
William & Mary is a public liberal arts and sciences research university, located in Williamsburg, Virginia, with nationally ranked undergraduate, graduate, professional programs, as well as select online programs. W&M is the second oldest institution of higher learning in the United States and combines the best features of an undergraduate college with the opportunities afforded by a modern research university. Its moderate size, dedicated faculty and staff, highly-motivated students, and distinctive history give William & Mary a unique character among public institutions, and create a learning environment that fosters close interaction among students and their faculty mentors.
IGNITE Program Objectives:
- Enhance William & Mary's faculty pipeline by establishing and developing significant meaningful relationships with prospects, especially those from groups underrepresented in the professoriate, with a focus on historically underrepresented minorities in the United States.
- Provide the opportunity for participants to gain a deeper understanding of the challenges and rewards of a faculty career.
- Develop a network of emerging scholars in priority research areas who could be candidates for current and future vacancies at William & Mary.
Participants are also expected to:
- Be a graduate student or post-doctoral scholar seeking a faculty position at a research intensive institution;
- Demonstrate career goals, research interests, and academic potential that align with William & Mary's mission and programs;
- Be able to meaningfully contribute to the university's continuing commitment to diversity and inclusive excellence as reflected by click (The Office of Diversity and Inclusion).
The IGNITE application will be available on January 1, 2020.
For more information or questions, please contact Dr. Rowan Lockwood, Chair of W&M Geology via email (rxlock at wm.edu).

Subject: [CIG-ALL] EGU 2020 session on 3D printing and AR: EOS4.3
Message-ID:
Dear colleagues,
We would like to draw your attention to the following education session at the EGU General Assembly in Vienna (3-8th May 2020):
EOS4.3: 3D toys in Earth Science: 3D-printing, AR (Augmented Reality) and VR (Virtual Reality) for outreach and pedagogy
3D representation technology is a fast developing field, made possible by progress in computing and reflected by the gaming and video industries. Notably, 3D-printing provides a cost-effective and tactile way to illustrate research concepts, while Augmented Reality (AR) or Virtual Reality (VR) allow to grasp complex processes and geometries using common smartphones or handheld devices. Using these technologies, 3-dimensional objects and datasets are developed that are well suited for outreach, teaching and wider public engagement.
The design of 3D models of the Earth on different scales based on photogrammetry, mapping and imagery, modelling and inverse modelling is a challenging task. Before 3D data sets (physically real or virtual) can be explored in outreach activities or teaching settings, several steps have to be taken which all come with their own issues: how to export data into the objects formats used in the 3D engineering community; how to feed objects into software to allow 3D-printing; how to manipulate virtual objects easily using handheld devices.
We welcome contributions that are focused on technical aspects of real or virtual realisations, as well as their use in pedagogy, outreach or public communication of Earth Sciences research topics.
Submit your abstracts here:
https://meetingorganizer.copernicus.org/EGU2020/session/34772
Note that submitting to EOS programme sessions does not count towards the one-regular-abstract-rule; you can thus still also submit an abstract to other programme group sessions.
This year the abstract submission deadline is 15 January 2020, 13:00 CET.
Please get in touch with us if you have any questions related to the session.
Best wishes,
Paula Koelemeijer, Royal Holloway (p.koelemeijer at rhul.ac.uk)
