This is a really useful option, thanks @pefarrell. Any chance you could add the mean patch size too? Could be useful to know if the min/max are particular outliers or not. |

We often would like to know what kind of sizes of patch problems we are dealing with in ASMStarPC and friends.
When using
-snes_view, PETSc prints out the size of the first patch on the first processor, but this isn't all that useful; really we want the minimum and maximum.This adds an option
-pc_star_print_patch_statisticsthat computes the minimum and maximum patch sizes and prints them out in the viewer, if requested.
