Abstract

This paper demonstrates large full-wave inverse-scattering solutions on the Blue Waters supercomputing facility. The high computational complexity of the distorted-Born iterative method (DBIM) is reduced with the multilevel fast multipole algorithm (MLFMA). A hierarchical parallelization of DBIM and MLFMA provides scaling to thousands of computing nodes of the supercomputer. Furthermore, we obtain considerable speedup with modern CPU+GPU architectures over conventional CPU+CPU ones. Results obtained on 4,096 GPU nodes demonstrate a near-real-time tomographic reconstruction, which is crucial for real-life imaging applications.
