Hierarchical low-rank compression exploiting symmetric boundary integral equations in transmission scattering

We propose an approach using matrix symmetry to accelerate hierarchical low-rank compression for wave transmission scattering. For Helmholtz transmission problems, we introduce a symmetric M\"uller-like boundary integral equation formulation. Although not of the second kind, this formulation creates no difficulties for...

Mixed-Precision Computing for Scientific Discovery: Formats, Co-Design, and Responsible Approximation

This paper organizes the landscape around seven coupled themes---number formats, floating-point emulation, emerging architectures, hardware/software co-design, relation to other approximations, software design, and precision as a multilevel resource ---and synthesizes the state of the art, future directions, and open q...

HPC-AutoResearch: Adapting Autonomous Research Systems for HPC through Split-Phase Execution and LLM-Based Code Generation

HPC-AutoResearch is presented, a proof-of-concept system for the autonomous execution of compiled-code research workflows in HPC-like environments that divides this sub-pipeline into five phases—planning, environment setup, coding, compilation, and execution—localizing failures within each phase and enabling iterative...
