BOINC Exceeds 2 Petaflop/s Barrier

Myrrh writes "Though an official announcement has not yet been made, it would appear that the BOINC project as a whole has exceeded two petaflop/s performance. The top page features this legend: '24-hour average: 2,793.53 TeraFLOPS.' According to last month's Top500 list of supercomputers, BOINC's performance is now beating that of the fastest supercomputer, RoadRunner, by more than a factor of two (with the caveat that BOINC has not been benchmarked on Linpack)."

Botnets

I wonder what the computing power is of some of the larger botnets. They are not likely to be listed in the "Top500".

Considering a spherical cow: 140 tons/hour CO2

Lets say a typical computer running BOINC contributes 1 GFlop at 100W (1e2W). So at 2e6 GFlops, tats 2e8W or 2e5 kW.

According to the energy department, we can assume that 1.4 pounds of CO2 per KWh, so that says BOINC is at ~3e5 pounds/hour of CO2, or about 140 tons/hour of CO2.

I get a very similar number if I back of the envelope what a coal plant should be based on ~500 tons/1 GW.

Once that's done, we can do a comparative analysis of CO2 of all the machines machines running WoW (factoring in the increased power draw of a machine with a higher end video card, plus increased disk & memory I/O compared to a machine running BOINC). I'd be willing to be the BOINC 24x7x365 number works out to be smaller, or at least on par with a WoW machine going 4 hours a night several times a week.

Waste is, and will always be, a relative term.
