Geophysics and Computers: Together on a journey from the earliest CPUs, GPUs and into the clouds

Geophysicists were quick in recognizing the potential of computers to help them carry out the many calculations needed when working to assess subsurface properties. Geophysicists are also experts in leveraging mathematics to create the computational frameworks needed to solve the key tasks they rely on in this work, like wavefield modeling, inversion, and large-scale optimization. In this presentation I will review how the field of geophysics, or maybe more accurately, computational geophysics have evolved along with the evolution of computers as a framing for offering some thoughts on where this journey might lead in the future.

Although many of the mathematical methods rely on approximations in the physics and geometry of the problem (dimensionality), the frontier of computational geophysics has pretty much tracked the frontier of computing by progressively adopting more accurate mathematical models and better physics in their problem definition. At any time, geophysical algorithms for imaging and inversion were pushing the limits of what was possible with the best and largest computers, quickly turning the industry into a dominant player in the field of high-performance computing (HPC). The leading companies deployed HPC infrastructure that rivaled that of the national labs, using this ever-increasing capability to solve ever more difficult subsurface imaging problems, unlocking vital energy reserves as a result. Can the growth in compute power continue indefinitely?

There is no way of predicting this, but I will argue that the emergence of cloud computing along with the economic conditions surrounding the industry, are forcing the development and adoption of new approaches to computing. Cloud computing has been a game changer for so many things in society, including geophysics, but it can sometimes be hard to see how this is the case unless we unpack the ‘cloud stack’ within the correct context. The hardware and computers are maybe the same, but the cloud services offer up new and exciting ways to think about and address the computational challenges. Although I will not endeavor to provide firm answers to this question, I will review multiple, emerging, cloud-based technologies that can impact the field of geophysics and be leveraged by the many clever people that work in the field, from server-less architecture applied to solving large-scale modeling and optimization to the role of AI as manifested in the fast evolving field of very large language models.

By adopting a software-defined computational framework, I postulate that a similar computational growth rate that the field has benefitted from in the past can also be sustained going forward, allowing new insights to be gained and help provide real a foundation for tackling some of the truly hard geophysical problems that are still out there.

Speaker Bio: Dr. Sverre Brandsberg-Dahl is the CTO for Microsoft’s Energy Engineering organization. Here he works with a range of engineering teams to bring the latest technological developments in Cloud Computing and AI to the energy industry. With a passion for technology and innovation, he is helping to position Microsoft with customers, partners, and governments as they accelerate their adoption of cloud technology, while giving equal focus to the transition to clean power and emissions management.
