Next generation experimental facilities generate data at rates that overwhelm conventional processing and demand real-time analysis at the source. Analog computing, which exploits the continuous dynamics of physical systems to perform computation, promises a transformative path toward orders-of-magnitude gains in energy efficiency and time-to-solution for scientific workloads.</p> <p>The workshop’s findings also identified several cross-cutting challenges underpinning all six PRDs, including a mathematical theory of continuous computation under noise, programming abstractions and compiler toolchains, and community benchmarking infrastructure, emphasizing the needs for a coordinated, multi-faceted effort to enable rapid progress in the area. The research directions outlined in the workshop report aim to guide the development of energy-efficient analog computing technologies that can support future scientific discoveries and address the growing energy demands of scientific computing and artificial intelligence.</p>
