Parallel Level set algorithm with MPI and accelerated on GPU
arXiv:1612.04040
Abstract
Level set method has been used to capture interface motion. Narrow band algorithm is applied to localize the solving of level-set PDE on global domain to a tube around interface. Due to the unknown evolving interface, narrow band algorithm brings load balance problem for parallelizing computing. This work presents a tool for evenly distributing work loads on CPUs. On the other hand, numerically solving level-set PDE only needs simple operations but on large grid points. This work also presents a GPU acceleration for solving level-set PDE using finite difference method.
