Is the FVP accurate in terms of measuring performance of programs? Is it cycle accurate? If I use clock_gettime to measure time taken on applications, is it meaningful? If not, is there an accurate way to measure performance of programs on the FVP?
Hi Eltro, I would not rely on the Fast Model for that level of accuracy. You may see that one implementation is 'better' than the other, but I would not rely on 'how much better', for exactly reasons like this (this is unfortunately the cost of keeping these models "fast").
Great, that is good to know. Of course I'll need to benchmark on real hardware in the end, but knowing that the numbers from the Fast Model are not completely off in this case is already quite helpful.
