SUMMARY:Modeling the Transport of Red Blood Cells and Platelets on Multipl
 e GPUs
DESCRIPTION:Minisymposium\nComputer Science and Applied Mathematics, Physi
 cs, Life Sciences, Engineering\n\nModeling the Transport of Red Blood Cell
 s and Platelets on Multiple GPUs\n\nKotsalos\n\nWe present a computational
  framework for the simulation of blood flow with fully resolved red blood 
 cells and platelets using a modular approach that consists of a lattice Bo
 ltzmann solver for the blood plasma, a novel finite element (FE) based sol
 ver for the deformable bodies and an immersed boundary method for the flui
 d-solid interaction. For the deformable bodies, we propose a nodal project
 ive FEM (npFEM) solver which has theoretical advantages over the more comm
 only used mass-spring systems (mesoscopic modeling), such as an unconditio
 nal stability, versatile material expressivity, and one set of parameters 
 to fully describe the behavior of the body at any mesh resolution. At the 
 same time, the method is substantially faster than other FEM solvers propo
 sed in this field and has an efficiency that is comparable to the mesoscop
 ic models. We use the open-source CFD solver Palabos for the blood plasma 
 simulation and the fluid-solid coupling. Palabos has a proven scalability 
 on multiple CPUs using MPI, while the npFEM solver is fully ported on GPUs
  using CUDA.
