This is just wrong. 100 gigabit ethernet switches are commonplace in the datacenters of companies like google, facebook, etc. Facebook even open sourced their second generation 100 gigabit switch design years ago. Combine this with the fact that LINPACK is not a benchmark that involves a lot of communication in the relative scheme of things. If any of them big players cared, they could probably destroy the top LINPACK numbers instantly. There are HPC benchmarks that they would have a harder time with, just not LINPACK.
