DescriptionComputational geophysics has reaped enormous benefits from advances in high performance computing; large forward and inverse models of myriad processes have allowed continually-expanding insight into the formation, evolution, and present-day structure of Earth and other planets. Multiscale phenomena, enormous spatial and temporal domains, and a growing set of relevant physical processes have created new challenges in scalability: scalable algorithms are required, data processing and I/O workloads grow, and software becomes more complex. Performance-driven co-design has become more and more important to address these scalability challenges - domain scientists, applied mathematicians, software developers, and HPC systems architects have growing incentive to work more closely. In this minisymposium, we discuss recent advances in the modelling of large-scale geodynamical processes in the earth and other terrestrial planets, including mantle and lithospheric dynamics. In particular, we focus on simulations and software taking advantage of scalable algorithms on modern HPC systems.
