This is true, but having an idea for what a node should give you and
running HPL on each node and comparing can reveal poorly performing
nodes (say due to BIOS/UEFI issues) and that will have knock on
effects for real codes if you are running tightly coupled MPI jobs or
are doing timing runs whilst tuning and you end up on a bad node.

cheers!
