We are deeply saddened by the passing of Distinguished Professor and CIG Director Louise Kellogg on April 15, 2019. Louise built innumerable ties among people, using her outstanding science, trans-disciplinary vision, and dedication to equity. Her family, friends and colleagues around the world are grieving her loss. Messages of sympathy and memories of Louise may be sent to memories-of-louise@ucdavis.edu. [In Memoriam]
Louise’s memorial will be held on Sunday, June 2, 2019 at 11 am in the Walter A. Buehler Alumni Center's AGR Hall at UC Davis. All are welcome. The memorial will be Quaker style, with silence at the beginning and end, with the opportunity for those attending to share as they wish. There will be a reception following the memorial.
Computational Infrastructure for Geodynamics (CIG) is a community-driven organization that advances Earth science by developing and disseminating software for geophysics and related fields.
In the next months, the new NSF-funded Petascale Computing System Fronterawill open for early testing at the Texas Advanced Computing Center (TACC). Frontera will be approximately twice as powerful as the current XSEDE flagship Stampede2. It will provide a “leadership-class” computing resource to enable much larger and more complex research challenges than previously possible and push the boundaries of currently available numerical methods.

NSF has awarded CIG 0.27 million node hours to participate in Frontera’s early testing phase from May 2019 to January 2020, which will be used to benchmark the performance of existing CIG software and further its scalability using new numerical methods in preparation for wider community use. Specifically, we will focus on testing and developing the CIG codes ASPECT and Calypso for mantle and core dynamics, respectively. In addition to research on numerical methods to reduce scalability bottlenecks applicable to a range of CIG codes, we will also conduct “proof-of-concept” simulations that target outstanding geophysical questions that were intractable with the current generation of HPC systems. ... continued [research highlight]
