How to calculate PPD with FAHMON?

post #1 of 12
Thread Starter 
What is the standardized approach to calculate PPD with FAHMON? It gives calculations based on the All Frames, Last Frame Only, Last Three Frames, Effective Rate. These all give different results for me. Which one do we use? All Frames gives the most, while Effective Rate gives the worst.

I use all frames, then use the benchmark feature if you want an in depth breakdown.

I use last 3 frames seems more accurate for the gpu clients if you do that.

I have used a few different versions of fahmon and it has never displayed PPD numbers for me. 4 of the 7 lines in the Work Unit Info box say "Unknown". Does anyone have this problem or know how to fix it?

Have you tried 'download new projects' maybe to update the Fahmon database?

I have also noticed with Fahmon, if I add up all the work units for the day and compare to Fahmon, it seems that Fahman really overestimates PPD, especially on very small work units like the GPU2. For one thing it doesn't take into account the small down time between work units. So while Fahmon says my 8800GTS is 5644.80 PPD, I'd be willing to bet tomorrow when I add them up for the day I don't get but about 5k actual points. Or maybe even less.

Thanks!

I try downloading new projects every time and no change. I can understand how PPD only calculates working time, some work units seem to take a while to upload too. Oh well, I don't use fahmon that much except to see how much time is left on a SMP work unit anyway. Just would have been nice to see everything work like it should. The same problem happens with both XP and Vista.

Are you sure you are setting the path in Fahmon to the home folder for F@H and not the work folder? That's weird

Sounds like you don't have it set to the right directory.

Yep, same folder with install.bat and fah.exe. It displays the ETA and progress bar fine but no PPD. I agree, it's weird.
