“Accelerating simulations of cerebrovascular blood flow through parallelization in time (PiTflow)”

Funder: EPCC
Duration: August 2017 - December 2018

HemeLB [1] is code designed to simulate blood flow in arteries using Lattice-Boltzmann methods (LBM). For complex geometries like the Circle of Willis, it scales up to 25k cores on the Cray XC30 supercomputer ARCHER but simulations still take several days to complete. Building on the work by Randles and Kaxiras [2], this project will integrate parallel-in-time integration capacities into HemeLB to extend scaling and reduce wall-clock times.
