Distributed finite element solution using model order reduction
<|reference_start|>Distributed finite element solution using model order reduction: We present a method for the distributed finite element solution of elliptic boundary value problems using model order reduction on each subdomain of the domain decomposition. We show that the error of the reduction can be succesfully controlled in the $H^1$ norm due to the properly weighted $l^2$ low-rank approximation. Our numerical results demonstrate the technique using tetrahedral meshes with up to 85 million degrees-of-freedom on a laptop computer by distributing the bulk of the model order reduction to the cloud.<|reference_end|>
