High Performance Computing 1
Measure
•Ttheor: theoretical peak performance; obtained by multiplying clock rate with no. of CPU and no. of FPU/CPU
•Treal:real performance on some specific operation e.g. vector add and multiply
•Tsustained: sustained performance on an application e.g. CFD
–             Tsustained <<   Treal  <<  Ttheor
