Attempting to break up the direct solver MR into smaller, more reviewable pieces. As a rundown

The code for this is mostly in the deprecated https://gitlab.tiker.net/inducer/pytential/-/merge_requests/137.

@inducer This should be ready for a look. It doesn't do much:

  • adds a data structure to hold the hierarchical cluster info from boxtree.Tree and merge cluster indices.
  • adds some helper functions to do the recursive skeletonization + simple tests.

Noticed a pending review. Figured it'd be better to submit it. :) Don't quite know how old this is.

Current level that is represented.

Is this avoidable?

Reworked this a while back, so not quite sure if your comment still applies?

Is this two things rather than one?

Yeah, separated into a ClusterTree and ClusterLevel with a ClusterTree.levels() iterator to go through them for the recursive skeletonization.

Naming could still be better probably?

logger.info("\n%s", case)

run_skeletonize_by_proxy(actx, case, case.resolutions[0], visualize=visualize)
dd = sym.DOFDescriptor(case.name, discr_stage=case.skel_discr_stage)

Update the test docstring to describe precisely what's being tested here.

@inducer I think inducer/ci-support@1475971 broke pylint (it's not finding the cython stuff anymore?). Any suggestion for a fix?
