• The recent advent of novel multi- and many-core architectures forces application programmers to deal with hardware-specific implementation details and to be familiar with software optimization techniques to benefit from new high-performance computing machines. An extra care must be taken for communication-intensive algorithms, which may be a bottleneck for forthcoming era of exascale computing. This paper aims to present a high level stencil framework implemented for the EULAG model that efficiently utilizes heterogeneous clusters. Only an efficient usage of both CPUs and GPUs with the flexible data decomposition method can lead to the maximum performance that scales communication-intensive elliptic solver with preconditioner.
