Application Scalability

HOMME: The High-Order Method Modeling Environment (HOMME) is a community model supported by the NSF and the DOE with contributions from NCAR, DOE laboratories and universities.

HOMME uses fully unstructured quadrilateral based finite element meshes on the sphere, such as the cubed-sphere mesh for quasi-uniform resolution.

Employing Spectral Element (SE) and Discontinuous Galerkin (DG) methods to solve the shallow water or the dry/moist primitive equations, HOMME is an extremely scalable and efficient dynamical core.

CESM: The Community Climate Model (CCM) was created by NCAR in 1983 as a freely available global atmosphere model for use by the wider climate research community. The formulation of the CCM has steadily improved over the past two decades, computers powerful enough to run the model have become relatively inexpensive and widely available, and usage of the model has become widespread in the university community, and at some national laboratories. 

DART: DART is a community facility for ensemble DA developed and maintained by the Data Assimilation Research Section (DAReS) at the National Center for Atmospheric Research (NCAR). DART provides modelers, observational scientists, and geophysicists with powerful, flexible DA tools that are easy to implement and use and can be customized to support efficient operational DA applications.

SPLSQR: This research project is to solve large-scale linear systems in seismic tomography. This is a collaborative project of Department of Computer Science and Department of Geology and Geophysics in University of Wyoming, and National Center for Atmospheric Research (NCAR). Structural seismology is the study of the internal structure of the Earth using seismic waves obtained on the surface. It plays an important role in a wide range of scientific as well as practical applications. Today, advances in computational technology, seismic instrumentation, and numerical methods have enabled large-scale seismic surveys and full-waveform tomographic inversions that can provide images of the Earth’s internal structure at unprecedented resolution. A key component in today’s seismic tomographic inversions is the solution of large-scale linear systems.
