Road to "AI for Science": Exploring Software Sustainability through "Couplers"

"Coupler" is originally a tool for coupling multiple simulation models such as atmosphere and ocean, structure and fluid. In recent years, computer systems and workloads have become more diverse, and the role of couplers in supercomputing has become more importan. In this lecture, we will focus on the "history" of couplers and consider what software sustainability means.
