Points for Discussion at CIG-SPICE Meeting

What are outstanding technical issues (e.g., boundary conditions, time integration, grids, rheologies, etc.) in the fields of wave propagation and rupture?
What computational methodologies are optimal for the various problems/scales/model complexities (e.g., reservoir, basin, regional, global)?
What are optimal strategies for computational grid generation (2D, 3D, hexahedral, tetrahedral, mixed)? Should we define standard formats for geophysical Earth models?
How should we parameterize observations for waveform inversion methods (structure and source inversion)?
How should we quantify misfits between observations and synthetics?
How can we improve the calculation and visualization of model uncertainties for waveform inversion?
Under what experimental conditions (local, regional, global, station density vs. number of events, event distribution, prior information, etc) is waveform inversion useful?
How should classical methods (e.g., ray-based tomography) be combined with 3D simulations?
What are major scientific problems that will most likely benefit from 3D wave simulation/inversion technology?

How can we coordinate developments in computational seismology on an international scale (working group, joint projects, www page, workshops etc)?
How can we collect, pool, and maintain software/tools efficiently?
What aspects need international cooperation (e.g., data and model formats, joint storage of observations and synthetics etc.)
What is necessary to facilitate the use of 3D simulation software for modelling/inversion studies particularly for observational Earth scientists?
Should forward and inverse modelling benchmarks be coordinated?
Should we team up with other scientific communities?
Does our community have sufficient computational resources?
Can we define some grand challenge problems in seismology?
