ABSTRACT:

We present simulations of blood and cancer cell separation in complex microfluidic channels with subcellular resolution, demonstrating unprecedented time to solution and performing at 42% of the nominal 39.4 Peta-instructions/s on the 18'688 nodes of the Titan supercomputer.

These simulations outperform by one to three orders of magnitude the current state-of-the-art in terms of numbers of cells and computational elements. We demonstrate an improvement of up to 30X over competing state-of-the-art solvers, thus setting the frontier of particle based simulations.

The present in silico lab-on-a-chip provides submicron resolution while accessing time scales relevant to engineering designs. The simulation setup follows the realism of the conditions and the geometric complexity of microfluidic experiments, and our results confirm the experimental findings. These simulations redefine the role of computational science for the development of microfluidic devices -- a technology that is becoming as important to medicine as integrated circuits have been to computers.
