Rethinking Scaffolding in LLM Tutors: The Interactional Mismatch Between Benchmarks and Real-World Deployments
Alexandra Neagu, Jeffrey T. H. Wong, Marcus Messer +2
A central pedagogical value evaluated in AI tutor benchmarks is scaffolding: guiding students through graduated steps toward a solution. Alignment and evaluation methods for embedd…
"How Do I ...?": Procedural Questions Predominate Student-LLM Chatbot Conversations
Alexandra Neagu, Marcus Messer, Peter Johnson +1
Providing scaffolding through educational chatbots built on Large Language Models (LLM) has potential risks and benefits that remain an open area of research. When students navigat…
Automated MPI-X code generation for scalable finite-difference solvers
George Bisbas, Rhodri Nelson, Mathias Louboutin +3
Partial differential equations (PDEs) are crucial in modeling diverse phenomena across scientific disciplines, including seismic and medical imaging, computational fluid dynamics,…
A Novel Immersed Boundary Approach for Irregular Topography with Acoustic Wave Equations
Edward Caunt, Rhodri Nelson, Fabio Luporini +1
Irregular terrain has a pronounced effect on the propagation of seismic and acoustic wavefields but is not straightforwardly reconciled with structured finite-difference (FD) metho…
Temporal blocking of finite-difference stencil operators with sparse "off-the-grid" sources
George Bisbas, Fabio Luporini, Mathias Louboutin +3
Stencil kernels dominate a range of scientific applications, including seismic and medical imaging, image processing, and neural networks. Temporal blocking is a performance optimi…
Scaling through abstractions -- high-performance vectorial wave simulations for seismic inversion with Devito
Mathias Louboutin, Fabio Luporini, Philipp Witte +5
[Devito] is an open-source Python project based on domain-specific language and compiler technology. Driven by the requirements of rapid HPC applications development in exploration…
