Matt,
Thanks for the quick reply. Users of our ALE3D hydro code at LLNL run very
large problems , which I believe can pass in large amounts of local integer
data to solver packages like HYPRE and PETSc for global solves. All of our
local integer data is stored with 32-bit indices and switching

Does PETSc have different data types for local ID’s and global ID’s? For
example, if PETSc is configured for 32-bit indices on very large problems with
say 10 billion degrees of freedoms (exceeding the limit of 32-bit indices for a
global ID) would it crash and require us to re-compile with
