Yeah I think Billy's made a mistake somewhere as I get a silly number for ppd if I use that formula

Grr. I'll get it right one of these days.

(time per frame in minutes * 100 frames per WU) = minutes per WU
(Minutes per WU / 1400 minutes per day) = days per WU
(Points per WU / days per WU) = points per day

so a bit of substituting yields

Points per day = (Points per WU / ((time per frame in minutes * 100 frames per WU) / 1400 minutes per day))

For Rich's benchmark:
376 / ((42.8166667 * 100) / 1 400) = 122.942779

I have no idea where FahMon's other 4 ppd are coming from. Maybe rounding errors? :confused:

rich99million · 2 May 2006 at 00:07

Or a little more friendly looking...

PPD = (Points per WU x 14) / Time per Frame in Mins

yup FahMon seems to have given extra points, like you say it is probably a rounding error somewhere - though being out by 4 is quite some error

I got the same as you when I worked it out btw so it has to be something FahMon has done
edit: I'm still using FahMon v1.8.1 so it may be something that has been fixed in the new version - have put off upgrading as I wanted to keep my benchmarks but I will probably put the new one on when I get my rigs sorted out

Joe42 · 2 May 2006 at 00:15

Aren't the benchmarks kept in a text file somewhere that you can keep when you upgrade?

They're kept in a .dat file that I don't know how to read. If I wasn't crap at C++ I could have a gander at the source code and tell you. But I'm am...

I'm pretty sure I read that v2 uses a different way of storing them and the two aren't interchangeable

It's no bother really - I can keep both versions and just run the old one when I want to check an old benchmark. I was only really keeping it for when we were running a benchmark site a long while back which has since been put on a very very slow back burner

BillytheImpaler · 2 May 2006 at 00:23

I just checked going from v2.x to v2.1.0c. The benchies carried over. I'll try again now with v1.8.

rich99million · 2 May 2006 at 00:25

i think I may have just assumed it wasn't possible due to this in the program revision history...

v2.0.0 (24/09/05)

* FahMon has been entirely rewritten and now works also with Linux. A lot of changes have been done, just check them! (Beware that file formats have changed and are not compatible with previous ones!)

BillytheImpaler · 2 May 2006 at 00:28

Confirmed by me. You're out of luck, Rich.

It's interesting to note that the v1.8 binary I just tested was 72 kiB. The v2.1.0c binary is 1.51 MiB

Joe42 · 2 May 2006 at 00:33

Ask them to put an 'export benchmarks' in the next version. You can copy and paste them all but its a lot of hassle.
I wouldn't mind an integrated vnc client aswell while they're on...

BillytheImpaler · 2 May 2006 at 00:36

Meh, it's feature bloat that makes me not use EMIII. I don't want my nice'n'quick FahMon to get the same way.

By the way, there's not a "they" it's one pHD student in France named François Ingelrest who writes it.

Bennah · 2 May 2006 at 11:09

Im using FahMon 2.1.0c here. Everything seems to be ok. No problems. Dont really need to change if a new version comes out.

Anyway, this rig had some time on its own with F@H last night. New info.

Wish that it stayed like this when I was using the rig too

I think you'll find the extra 4 ppd comes from the fact there's 1,440 minutes in a day, not 1,400 as you've put in your formula

hahahaaha - oops

can't believe I didn't notice that either

well that's another mystery solved then

Berserker · 4 May 2006 at 01:30

Well, that's a new one. First time I've come across pornography in the DC forum in 3½ years worth of browsing. :eek:

Keep it clean please.

I find it more disturbing that you'd be at less than 100% ever anyway :eek:

my x2 @ 2.7 is on the track :cool:

, hope to see a large turnover thanks to it

im commin' to get ya' peeps.

X2 Core1 ->
Min. Time / Frame : 06mn 25s - 222.17 ppd
Avg. Time / Frame : 06mn 25s - 222.17 ppd

after being stuck with some rubbish Gromacs WUs for the last couple of days I finally got something which the X2 likes

Just a shame they are only short WUs

not bad PPD though since there are no bonus points on these AFAIK

that's still at stock so can't wait to see what a bit of speeding-uppage will do

There's some better ram arriving soon that might improve things though.

rich99million · 5 May 2006 at 00:06

yeah there are some really terrible Gromacs WUs around at the moment

you should think about joining the beta team - my beta rig (currently an overclocked XP1700) has got nothing but DGros for weeks now, it doesn't like them anything like as much as the X2 does but they are still better points than the Gros
