Is 2.44 Trillion Unknowns the Largest Finite Element System that can be Solved Today?

Ulrich Ruede, Professor, Universitaet Erlangen-Nuernberg

Abstract

Supercomputers have progressed beyond the Peta-Scale, i.e. they are capable to perform in excess of 10^(15) operations per second. I will present parallel multigrid based solvers for FE problems with beyond a trillion unknowns. This is e.g. enough to discretize the whole volume of planet with a global resolution of about 1 km. Since the compute times are around 1 minute for computing a single solution, so that they can still be used reasonably e.g. within an implicit time stepping procedure or a nonlinear iteration.
