Abstract
FPGAs are fostering interest as energy-efficient accelerators for scientific simulations, including for methods operating on unstructured meshes. Considering the potential impact on high-performance computing, specific attention needs to be given to the scalability of such approaches. In this context, the networking capabilites of FPGA hardware and software stacks can play a crucial role to enable solutions that go beyond a traditional host-MPI and accelerator-offload model.
