摘要

In their work, Uphoff et al. (2004) presented optimization of the SeisSol code. For the reproducibility challenge during the Student Cluster Competition at SC18 we reproduce selected results from the mega-scale earthquake simulation by Uphoff et al. on our competition computer cluster. Our cluster configuration is a 4-node system with Intel Xeon Gold processors (96 cores total, Skylake architecture) running under a 3 kW power limit imposed by the competition. We ran the computations during a 48-h marathon along with other competition applications. We successfully reproduced an increase in FLOPS w.r.t. the discretization order. Results we obtained for scaling are not consistent with the original work due to crucial hardware differences. (C) 2019 Elsevier B.V. All rights reserved.
