Accelerating Bio-Inspired MAV Computations using GPUs

In the paper, we discuss the use of general purpose GPUs for simulating the flapping flight of a fruit bat. The highly deformable prescribed wing motion is simulated using an Immersed Boundary Method (IBM). These computations are optimized for the GPU platform using CUDA Fortran to obtain about six times speed up over CPUs. Strong scaling study and code profiling is performed to understand code characteristics to develop a path for future improvements.
