“Trestles allowed us to perform calculations on larger molecular systems that are difficult to calculate elsewhere,” said Aspuru-Guzik. “We were able to perform more complex calculations of systems with more than 300 electrons, which are currently impossible to run on smaller systems. As well as large molecules, the computing power of Trestles let us gather most interesting and promising candidate molecules at a higher level of theory, resulting in a much improved molecular characterization of those systems of interest.”
