Enabling Bitwise Reproducibility for the Unstructured Computational Motif

Enabling Bitwise Reproducibility for the Unstructured Computational Motif

In this paper we identify the causes of numerical non-reproducibility in the unstructured mesh computational motif, a class of algorithms commonly used for the solution of PDEs. We introduce a number of parallel and distributed algorithms to address nondeterminism in the order of floating-point comp...
