Abstract

In this paper, we describe a verified implementation of the Levenshtein distance problem on a GPU cluster using MPI and OpenCL. The implementation is based on an existing verified single GPU implementation. The speed of the implementation is higher on a cluster, but the efficiency is affected by the overhead, which is caused by the extra communication between nodes.
