Now... Witness the power of this fully armed and operational i7!!!

[ozzlo]

So my first bigadv 8 core Workunit cleared today and all I can say is holy smokes!!! :burn::burn:

That's about 20,000-25,000 PPD, and i've got like a million other programs running in the background and i've been using my computer all day today and yesterday... I can't imagine what this thing could do if it was a dedicated folder :eek:


If you have an i7 and you've been slacking setting up the 8 core VM all I can say is that you've been missing out!!! i'm seeing an 16,000 PPD increase... That's like an entire 2nd i7 and 2nd gpu...

[ihrsetrdr]

I've never been quite clear about the math here- a p2682 is worth 25403 points, it takes my i7 2.9 days to complete, then that's looking like 7596 PPD.

What part am I missing? :chair:

[ozzlo]

I dunno, Extreme stats is listing this as a single workunit which I got 54,819 points for... It took between 2 and 2.5 days...

The incredible bonus factor! 2.9 days should yield approx. 48 - 51k points - or about 16,000+ ppd.

You won't get much more if it were dedicated. What's the clocks on that baby?

Here's the data straight from the Stanford database on my last bigadv unit from my currently dedicated i7 w/8-Core VM @ 3.8GHz.

58376.1 2009-12-08 14:33:40 2681 17 7 20

...and by the way, if you haven't updated to HFM v0.4.6.99 (http://code.google.com/p/hfm-net/) yet... you should, it calculates this Bonus Credit & PPD for you on the fly. ;)

[NV]

My i7, also running at 3.8GHz, is getting just under 58k per WU in native linux. Its not a dedicated folder (it's my only computer...) but it's not running much else most of the time. I see frame times go up from about 32 minutes to 40 or so if I'm actually making modest use of the computer, longer if I use it heavily.

I'm getting something like 23-24k ppd on the CPU right now, but I plan on tweaking my OC in the coming weeks and possibly getting more out of this thing :sn:. Gotta love the i7s.

The early completion bonus equation drives the points up.
The Multiplier is calculated as below in Excel format;

multiplier = IF(Kfactor>0,IF(WU-Time<=Preferred_Deadline,max(SQRT(Final_Deadline*Kfacto r/WU_Time)),1),1)

KFactor is found in the last column of psummary.
WU_Time is the time it take you to complete the WU including download and upload.

Plugging in some numbers based on a -bigadv WU with TPF of 38:00/frame (2.6389 TPU) to calculate the WU credit:
WU_Credit = Base_Value x SQRT(Final_Deadline x Kfactor / WU_Time)
WU_Credit = 25403 x SQRT(6 x 2 / 2.6389)
WU_Credit = 25403 x 2.1324
WU_Credit = 54,169.36 (PPD = 54,169.36/2.6389 = 20,527)

THe Stanford stats will show that amount awarded for the return of the WU.

Harlam has made this much simpler for us by including the calc in HFM. This is going to become quite important based on this blurb from Dr. Pande concerning SMP2 WUs:

In particular, we will use early-completion bonuses, which we have been testing with the bigadv work unit program, more extensively for SMP2 cores.

[Bobnova]

Someone buy me an i7! I want bigadv WUs, they'd about triple my PPD, and that's if i shut off the entire farm except the i7.

[ihrsetrdr]

Well, I hate to admit it, but math is not my strong suit- since I'm left-handed(right headed) I'm not a math genius(Einstein was a lefty, and was a math genius but he was smarter than me), so the bonus equation will take some time to soak in my brain. :o

HFM.NET(thanks harlam :beer:) is showing my one i7 running SMP2 @13360 PPD right now; I started up a bigadv client on the other i7 right after the last WU completed, but it's only done 2 frames, not showing any TPF or PPD right now. Maybe the client needs to progress past at least 3 frames for those calcs to register...?

The bigadv client was one of the first I had run on my first Asrock X58/17 920 rig, it trashed before completion(wasting 2 days of production), which I guess is why I've not embraced bigadv wholeheartedly. I'll see this through, and GET my bonus points yet. ;)

I am curious if there is any difference in folding power between the i7 socket 1366 and the i7 socket 1156 if clocked the same.

[Shiggity]

Awesome!

It's hard to believe how far this project has come in only 18 months!

[ihrsetrdr]

I am curious if there is any difference in folding power between the i7 socket 1366 and the i7 socket 1156 if clocked the same.

Well, the attractive feature of the i7 chip is that it give you 4 real cores plus 4 HT 'cores', whereas the i5 does not have hyperthreading.

Edit: see post #17 (http://www.ocforums.com/showpost.php?p=6326425&postcount=17).

[torin3]

Well, the attractive feature of the i7 chip is that it give you 4 real cores plus 4 HT 'cores', whereas the i5 does not have hyperthreading.

Which means that the i5 will not run the bonus WUs, as it has only 4 cores available, and you need 8.

[Khemikal]

I am curious if there is any difference in folding power between the i7 socket 1366 and the i7 socket 1156 if clocked the same.

Me too. I would love to grab an i7 860 and do a full upgrade. I'm guessing there wouldn't be much, if any, difference mhz per mhz comparing the 1366 vs 1156.

[glussier]

Well, the I7 socket 1156 i7 860 and 870 can.

I saw "socket 1156" and thought "i5"...

:o


Well, the I7 socket 1156 i7 860 and 870 can.

Yes, and a little higher clock for a little less $$ I see. Are there still socket burning issues (http://www.overclockers.com/socket-1156-i5i7-burning-issues/) with the current 1156 boards?

[orion456]

DO NOT be too proud of this technological miracle,
its power is insignificant compared to the FORCE


on the other hand, 50,000 points is an awesome boost!

[otogrim]

Finished 2 of these they're crazy!

Almost fell out of my chair laughing at that one... Wife is looking at me weird now :chair:

When making my first i7 purchase decision those "burning issues" weighed heavy on my decision making. Although we're not "extreme" OC'ers. I would guesstimate that we OC'ing DC'ers put much more stress on our systems (not just the cpu) over their life than the OC'ing Gamer (which I believe is the majority of the community) due to our 24x7 style of "play". :D

So although this might seem to be an "extreme" voltage kind of issue... you never know if moderate voltage, under load, over time might also be an issue... only time will tell - and I didn't feel like being the guinea pig. ;)

[ozzlo]

^^^ Yup I was so happy when I found out intel was releasing the performance line first and not last.

[ihrsetrdr]

I'll see this through, and GET my bonus points yet. ;)


Cha-ching! P2681 finally credited, along with bonus points. :D

My other i7 is mysteriously just doing p6012s; I must have set that machine up on my bbd*

:shrug:
