AIX

Yep, that was the official thing I mentioned in my 1st post and I think I have to take a closer look at those values and descriptions.
Currently I might simply have a look for our processors ie.

Code:

p570, p5 1,9GHz
p590, p5 2.1GHz

and just compare them with some middle sized p7 boxes to get some kind of ratios.

Tbh I am not sure if we use more int or fp base calculations. That's something I never (or anyone in our company) lost a thought about.

Well, for fp to get interesting, someone would be modeling airflow on a wing or something like that, with huge matrixes of fp (more at home on a SIMD box but $$). Even applications with considerable fp still use many int operations to calculate addresses. Applications more in strings and RDBMS get very little from fp prowess.

Our IBM var ran a tool to capture system utilization during heavy loads.

I would post the link but cannot, I need at least 5 posts.

I am not sure if it cost the company money but it might be one of those spend a little now and save a lot later.
