Description

  • expand blueprint index to take options node
  • add option for new map-based bp index (supports all cases including AMR)
  • add options to compute more metadata
    • extents (for coordsets and fields)
    • number of elements
    • sizes (total strided bytes per MPI task, and total bytes per field, etc)

We want these metadata cases to be optional b/c they involve examining problem-sized arrays

Research direction

No files, tests, or entry points are named in the issue. Start by locating the blueprint index implementation and its current options handling, then determine how optional map-based indexing and metadata computation should be represented; done requires optional support for AMR indexing, extents, element counts, and byte-size metadata.
