Abstract

-point computations are not deterministic on parallel environments. Therefore, due to the non-associativity of the floating-point addition, non-reproducibility of results might become a critical issue. We present two parallel solvers for triangular systems. Both solvers provide a numerically reproducible solution independently from the running environment.
