Bench Testing CPU Performance


We need to bench test the CPU horse power of a server we have on evaluation. This is a 24 CPU box. A colleague of mine wrote  a simple C program that induces Floating Point Operations on each CPU by a simple looping, we have been running this at about 20 billion loops/FPO's. The C program provides a parameter for us to say how many CPU's to load up and I was wondering when you write in C how you process a loop on a specific CPU (i.e. any 1 of the 24). Looking at the source the C program says "execute( cpu, loop counter)" is this correct ?
