No idea where to ask this so I figured I'd ask where I know there's going to be other uber-geeks. :P

I can't bloody remember the formula for calculating Gflops in a supercomputer or a cluster, i.e. put in the variable which equals the number of CPUs, the variable which equals the average speed of the cpus or somesuch... I can't even remember where I found the webpage and googling around several times hasn't really found much of anything beyond white papers that only vaguely address any sort of formula beyond ones specifically meant for certain systems or cpus.

Thanks in advance.
