[petsc-users] hypre-ILU vs hypre Euclid

[Alexander Lindsay]

I know that PETSc has hooks for Euclid but I discovered today that it does
not support 64 bit indices, which many MOOSE applications need. This would
probably be more appropriate for a hypre support forum (does anyone know if
such a forum exists other than opening GitHub issues?), but does anyone
here know what the difference between hypre-ILU and hypre-Euclid are? From
the docs it seems they are both supposed to be parallel ILU solvers.

If hypre-ILU worked with 64 bit indices (I can probably check this sifting
through the sources), then I would probably add hooks for it in PETSc
(AFAICT those don't exist at present).
