Exascale Drives Industry Innovation for a Better Future

By Caryn Meissner, ECP contributing writer   Outside the high-performance computing, or HPC, community, exascale may seem more like fodder for science fiction than a powerful tool for scientific research. Yet, when seen through the lens of real-world applications, exascale computing goes from ethereal concept to tangible reality with exceptional…
