As biological research demands simulations with increasingly larger cell counts, optimizing these models for largescale deployment on heterogeneous supercomputing resources becomes crucial. This requires the redesign of fluid-structure interaction tasks written around distributed data structures built for CPU-based systems, where design flexibility and overall memory footprint are key considerations, to instead be performant on CPU-GPU machines. This paper describes the trade-offs of offloading communication tasks to the GPUs and the corresponding changes to the underlying data structures required, along with new algorithms that significantly reduce time-to-solution. At scale performance of our GPU implementation is evaluated on the Polaris and Frontier leadership systems. Real-world workloads involving millions of deformable cells are evaluated. We analyze the competing factors that come into play when designing a communication layer for a fluid-structure interaction code, including code efficiency, complexity, and GPU memory demands, and offer advice to other high performance computing applications facing similar decisions.
