Rmax/Rpeak= 0.83 seems a good guess based on one very similar system on the Top500. Thus I come up with a number of around 1.34 TeraFLOPS for my cluster of 24 servers. Does the value seem reasonable ballpark? Nothing too accurate but I do not want to be an order of magnitude off. [maybe a decimal mistake in math! ] Hardware: Dell PowerEdgeSC1345's.
