ABSTRACT:
Stencil computations are a common class of operations that appear in many
computational scientific and engineering applications. Stencil computations
often benefit from compile-time analysis, exploiting data-locality, and
parallelism. Post-processing of discontinuous Galerkin (dG) simulation
solutions with B-spline kernels is an example of a numerical method which
requires evaluating computationally intensive stencil operations over a mesh.
Previous work on stencil computations has focused on structured meshes, while
giving little attention to unstructured meshes. Performing stencil operations
over an unstructured mesh requires sampling of heterogeneous elements which
often leads to inefficient memory access patterns and limits data
locality/reuse. In this paper, we present an efficient method for performing
stencil computations over unstructured meshes which increases data-locality and
cache efficiency, and a scalable approach for stencil tiling and concurrent
execution. We provide experimental results in the context of post-processing of
dG solutions that demonstrate the effectiveness of our approach.
