Preparing the HARVEY Circulatory Modeling Code for Exascale
- Lawrence Livermore National Laboratory (LLNL), Livermore, CA (United States)
Atherosclerotic cardiovascular disease is the leading global cause of death, accounting for more than 17.3 million deaths per year, a number that is expected to grow to more than 23.6 million by 2030. Personalized computational models of the coronary arteries can be used to analyze the influence that a narrowing of the blood vessel can have on the associated hemodynamics. To achieve the necessary scale and precision in circulatory models with explicit fluid coupled to deformable cell models, our simulation code HARVEY must be designed to efficiently use current and next-generation HPC architectures. This Feasibility Study will involve a careful assessment and redesign of the code’s core data structure to prepare for GPU-accelerated systems like Sierra as well as next-generation architectures like the A21 exascale system.
