I have a question regarding the reported ALU:Fetch ratios.

For the black scholes model sample (and the other samples as well), there is no branching or control flow so the calculated ALU:Fetch ratio should be quite simple to obtain.

However, the SKA gives 440 ALU and 13 Fetch for an ALU:Fetch of 110.00.

Profiler gives 440 ALU and 13 Fetch for an ALU:Fetch of 33.85.

While the ALU and Fetch numbers are consistent, somehow the ALU:Fetch ratio numbers are NOT.

The given numbers are for 5870.

Any explanation??

It seems that if you take 440/13 = 33.85 but then why does the SKA report 110?

I'm going to assume that the SKA still takes into account the 4:1 ratio while the profiler does not, this seems to be the case for all the samples I have looked at.
