SUMMARY:High-Resolution Simulation of Earthquake Recurrence Enabled by Opt
 imization for Multi-Core CPUs and Large-Scale Parallelization
DESCRIPTION:Posters, Research Posters\n\nHigh-Resolution Simulation of Ear
 thquake Recurrence Enabled by Optimization for Multi-Core CPUs and Large-S
 cale Parallelization\n\nAndo, Ozawa, Ida, Hoshino, Muramatsu...\n\nWe have
  successfully developed an efficient algorithm capable of computation of N
 =1 million elements and 0.1 million time-steps. Strong-scaling analyses sh
 ow that the algorithm exhibits the good scalability for OpenMP / MPI of 8 
 threads and more than 10000 cores (~200 nodes). This capacity is necessary
  to simulate the nationwide fault activity for the Japanese Islands with t
 he current HPC systems. The algorithm is applied to simulate the 15 thousa
 nd years of the earthquake recurrence history along one of the largest act
 ive faults in SW Japan, the Median Tectonic line. We demonstrate that the 
 optimized algorithm is a powerful tool enabling us to build a physics-base
 d method applied to long-term  forecast of earthquake generation.\n\nRegis
