https://community.intel.com/t5/Analyzers/How-Can-I-count-the-flops-of-my-code-using-VTune/m-p/987989#M10603 Thank you so much! I only need the number of floating point operations in my code. So I needn't divide by the excutive time, right?

I think I have made a mistake. I need to count the floating point operation in my code. I have a PC with Pentium III and a PC with Pentium IV. Thanks!

On the PIII you can use the event FP Operations Retired. However these will not give you a true meaning of FLOPs since they do not count floating point calculations using the SSE and SSE2 instructions (Pentium 4 only). Generally when calculating FLOPs you looking at you algorithm at a high level and see how many floating point operations there are per iteration. Than you multiply that by the total interations and divide by the execution time.
