[Trilinos-Users] Ifpack(IC) + Belox(Tpetra)

[Erik Boman]

The best work-around for now is to use Ifpack2::RILUK. Since this does 
ILU(k) without pivoting, the incomplete factors you get will be 
essentially the same as if you did IC (only the diagonal scaling is 
different in L and U). Sure, this is twice as many flops in the setup 
but that cost can be amortized over many solves so no big deal.
