This document discusses computational biophysics, including current trends, needs, and challenges regarding high-performance computing (HPC). Computational biophysics uses physics-based modeling and simulation to study biological processes at the molecular level. Simulation sizes have increased from 20,000 atoms in 2000 to over 3 million atoms currently. Emerging needs include faster CPUs, solid state storage, and GPUs to analyze large simulation data in real time. Connectivity and infrastructure also need improvements to enable larger multicenter simulations. Overall, computational biophysics provides insights into cellular functions and mechanisms of life through increasingly detailed molecular simulations.
