An HPC Approach to Accelerate Tensor Decompositions

Markus Hellgren, Erna Begovic Kovac, Hans O. Karlsson +1

Quantum systems grow in complexity so rapidly that even modest models become difficult to simulate, creating a strong need for methods that can handle high-dimensional data, also k…

General framework for re-assuring numerical reliability in parallel Krylov solvers: A case of BiCGStab methods

Roman Iakymchuk, Jose I. Aliaga

Parallel implementations of Krylov subspace methods often help to accelerate the procedure of finding an approximate solution of a linear system. However, such parallelization coup…
