You saw the log message about disabling libHilbert, but I guess you missed the discussion about why? It was giving us collisions. Two separate users managed to find cases where ~10 levels of refinement would cause libHilbert to be unable to distinguish between two nodes, leading to an I/O assertion failure in debug modes or a corrupt output file in optimized modes. We're not turning it back on until that's fixed. But of course we don't want to disable MPI for everyone either. I've written a tolerable default global_indices(), and I'm testing it now. The testing will be unfortunately less than such a low lying change deserves, but better to have code that might not work than code that's definitely been found to have failure cases... --- Roy > Or we should disable MPI in configure if > Hilbert is > disabled.
