Is superlu doing full (dense) LU or ILU? If it's the former, that would explain why it's better... Anyway, it's probably fine for small examples like this one to use -pc_type lu. That way our examples don't require superlu/hypre just to run. -- John ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
