Nvidia's newest tensor cores that are available on the latest A100 GPUs are expected to greatly accelerate deep machine learning workloads. This master project, however, wants to investigate whether these latest tensor cores can also be used for physics-based simulations, with cardiac modeling as the target domain.

Proper functioning of the heart relies on coordinated electrical activities of the cardiac cells. In-depth scientific understanding requires in-silico simulations of the individual cells. Advanced mathematical models of the cardiac cells are continuously being derived, but manually implementing these models as efficient software code is both cumbersome and challenging. Automated code generation is thus an important strategy.

In the context of cardiac simulations, the irregular 3D volume of the heart poses a computational challenge. Not only sophisticated 3D mesh generation techniques have to be applied, but the resulting unstructured data structure can seriously hamper the overall computing speed, on both conventional single-core computers and modern parallel computers.
