I didn't mean any special insult to the latest top 500 entry. Rather, that was a comment on the general nature of that list. Does anyone know, off-hand, how often these big machines run with all compute nodes dedicated to a single message-passing job? My guess is less than 1% of the time, and for the most part these machines are used as batch servers for smaller (N=512, 64, 32, etc) Amber/Gaussian/CFD like jobs.
Am I far off the mark? Along similar lines, has Google or Amazon ever published their batch job capacity (it must be in petaflops...)
