- The unit of computing power kSI2K corresponds to one Intel Xeon 2.8 GHz processor: http://www1.jinr.ru/Pepan/2005-v36/v-36-1/pdf/v-36-1_02.pdf
- Giga Flop: Xeon processors execute 2 floating point operations per clock cycle. A Xeon with 2.4 GHz is able to execute up to 4.8 billions of floating point operations per second: 2 operations / clock cycle X 2.4 x 10^9 clock cycles / sec = 4.8 GFlops
