A Sparse Distributed Gigascale Resolution Material Point Method

SessionMost Def: Fast, Large and Learned Deformables

DescriptionWe present a four-layer distributed simulation system along with an MPM (Material Point Method) adaptation. Using hierarchical block-tile-cell sparse grids and an efficient dynamic load balance optimization, our system can be distributed to multiple MPI ranks with user-selected backend HPC programming models, including OpenMP and CUDA.
