Computation’s Amanda Randles and Erik Draeger and University of Arizona researcher Peter Bailey are coauthors of a paper that won the Best Paper Award at the International Conference on Computational Science, held in Reykjavik, Iceland, at the beginning of the month.
The winning paper, “Massively Parallel Simulations of Hemodynamics in the Primary Large Arteries of the Human Vasculature,” demonstrated, for the first time, large (>500 cm) fluid dynamics simulations of the circulatory system modeled at resolutions as high as 10 μm. Their computational model of three-dimensional and unsteady hemodynamics within the primary large arteries of humans ran on 1,572,864 cores of Sequoia.
Models of large regions of the circulatory system are needed to study the impact of local factors on global hemodynamics and to inform next-generation drug delivery mechanisms. The HARVEY code successfully addresses key challenges that can hinder effective solution of image-based hemodynamics on contemporary supercomputers, such as limited memory capacity and bandwidth, flexible load balancing, and scalability.
Their paper bested 81 others that were accepted to the conference (out of 248 submissions—a 33% acceptance rate).
