cuIBM -- A GPU-accelerated Immersed Boundary Method

16 Sep 2011  ·  Simon K Layton, Anush Krishnan, Lorena A. Barba ·

A projection-based immersed boundary method is dominated by sparse linear algebra routines. Using the open-source Cusp library, we observe a speedup (with respect to a single CPU core) which reflects the constraints of a bandwidth-dominated problem on the GPU. Nevertheless, GPUs offer the capacity to solve large problems on commodity hardware. This work includes validation and a convergence study of the GPU-accelerated IBM, and various optimizations.
