In this work, we compare the performance of two partitioning algorithms, Recursive Coordinate Bisection and Recursive Inertial Bisection, in the mesh generation of ALE3D, a massively parallel physics simulation. Analyzing load balance, grind time, and ghost zones on a 10 million element, 512 domain mesh, we compare time invested in RIB with time saved in the subsequent simulation’s runtime.
