You're off by three orders of magnitude.

My point of reference is that back in undergrad (~10-15 years ago), I recall a class assignment where we had to optimize matrix multiplication on a CPU; typical good parallel implementations achieved about 100-130 gigaflops (on a... Nehalem or Westmere Xeon, I think?).

You are 100% correct, I lost a full prefix of performance there. Edited my message.

Which does make the clusters a fair bit less impressive, but also a lot more sensibly sized.
