PETSc binary formats can't carry enough metadata to be usefully plottable without user interaction. I think I'm still in favor of a SQLite backend (for simplicity and versatility) indexing binary files written using MPI-IO. Most visualization and metadata tasks should be answerable in 1-line SQL queries instead of custom page-long graph traversals. >>> On a different but not unrelated topic, Imtiaz who had started looking > at the vtk IO had to leave LSU after our international services office > screwed up his immigration paperwork...
