Scientific progress in drug discovery hinges on our ability to understand and manipulate matter at large molecular scales. However, existing computational approaches for drug discovery are often either too slow or lack the accuracy required for reliable predictions, necessitating costly and time-consuming physical experimentation. These constraints hinder innovation, prolong development cycles, and introduce limitations inherent to synthesis and observation. To overcome these challenges, we present a pioneering digital chemistry framework that integrates many-GPU high-performance computing, computational quantum chemistry, and machine learning, delivering unprecedented accuracy and scalability for drug discovery. By leveraging novel algorithms and software optimizations, we overcome the steep computational cost and efficiency limitations that have historically hindered the use of quantum chemistry at large molecular scales and useful speed. Awarded the 2024 Gordon Bell Prize, our approach enables, for the first time, quantum-level simulations of bioscale molecular systems with accuracy close to physical experimentation. Through exascale supercomputing, automated workflows, and machine learning models trained on quantum-accurate data, we streamline end-to-end simulation and design processes. These intelligent workflows reduce dependency on laboratory experiments, offering a fully automatable, cost-effective, adaptive, and highly precise solution for investigating complex molecular phenomena. The result is a powerful technology that accelerates drug discovery, enhances molecular design, and redefines in-silico research possibilities across chemistry and biology.
