A Spatio-temporal Coupling Method to Reduce the Time-to-Solution of Cardiovascular Simulations
Abstract
We present a new parallel-in-time method designed to reduce the overall time-to-solution
of a patient-specific cardiovascular flow simulation. Using a modified Para real algorithm,
our approach extends strong scalability beyond spatial parallelism with fully controllable
accuracy and no decrease in stability. We discuss the coupling of spatial and temporal
domain decompositions used in our implementation, and showcase the use of the method
on a study of blood flow through the aorta. We observe an additional 40% reduction
in overall wall clock time with no significant loss of accuracy, in agreement with
a predictive performance model.

My research in biomedical simulation and high-performance computing focuses on the
development of new computational tools that we use to provide insight into the localization
and development of human diseases ranging from atherosclerosis to cancer.
