Student Cluster Competition 2018, Team Northeastern University: Reproducing Performance of a Multi-Physics Simulations of the Tsunamigenic 2004 Sumatra Megathrust Earthquake on the AMD EPYC 7551 Architecture

This paper evaluates the reproducibility of a Supercomputing 17 paper titled Extreme Scale Multi-Physics Simulations of the Tsunamigenic 2004 Sumatra Megathrust Earthquake. We evaluate reproducibility on a significantly smaller computer system than used in the original work. We found that we able to demonstrate reproducibility of the multi-physics simulations on a single-node system, as well as confirm multi-node scaling. However, reproducibility of the visual and geophysical simulation results were inconclusive due to issues related to input parameters provided to our model. The SC 17 paper provided results for both CPU-based simulations as well as Xeon Phi based simulations. Since our cluster uses NVIDIA V100s for acceleration, we are only able to assess the CPU-based results in terms of reproducibility.
