According to the top 500 website, Jaguar's peak value is 2.33 petaflops. The max value is 1.80. [1]


As defined by top 500, peak vs max:
Rmax - Maximal LINPACK performance achieved [2]
Rpeak - Theoretical peak performance [2]

IIRC LINPAK is the benchmark program they use.

And even Rmax isn't a fair comparison as the organic structure of BOINC means that measuring Rmax or Rpeak would be impossible or have no meaning (when will every single BOINC computer be on at 100% utilization simultaneously?).

Perhaps in the future, take another step and list the Rmax values of the top 10 computers - then you could show how BOINC is number 2 (thereby discussing the weakness of the comparison and a little bit about BOINC structure).

I think it would be neat to integrate a plot of BOINC's 24 hour average compared with time. I don't know where to find that though.

I also think this is really neat that you did this. I need to introduce it to some people I know.
