NVIDIA CORES:

Nvidia core 1.19 http://foldingforum.org/viewtopic.php?f=52&t=6690

If you are having problems with v1.15 or v1.18, please try replacing it with this newer version. This version of the code removed some of the optimizations that were causing EUEs for WUs for larger proteins. It worked well for most people in beta testing over the weekend. It can be downloaded from http://www.stanford.edu/~friedrim/FahCore_11.exe. Thanks.

Nvidia core 1.18 http://foldingforum.org/viewtopic.php?f=52&t=6552

No showstoppers were found during the beta testing of v1.18, but we do not want to force a core upgrade at this time. If you are having problems with v1.15, please try replacing it with this newer version. It can be downloaded from http://www.stanford.edu/~friedrim/FahCore_11.exe. Thanks.

wow, one is up to over 5500ppd on a 8800gt. this is pretty cool. I've never seen over 5120 on this one before..

Are you sure it's not because of the new core 1.13 or 1.15?

[MikeB12]

ahhh! you're right... I just checked my logs...

my systray clients were pulling:
Folding@Home GPU Core - Beta
Version 1.09



and the console clients are pulling:
Folding@Home GPU Core - Beta
Version 1.15


I also tried increasing my 9800gt shader to 1836 which was stable on 1.09, but it's not on 1.15
so that new core must have some utilization improvements in it... I went back to 1783 and it's stable again.

[MikeB12]

I like the ppd improvement with this one: (core 1.09 vs core 1.15) I wasn't pulling the new core until I switched to console. but I didn't try deleting the core in systray first to make it dl a new one. someone should try that and see if systray will pull a new core.

Hm I may have to try this out when I have time

[WFO]

The systray client will pull core 1.15 if you delete/rename the old core. Mine just did. Thanks for the heads up Mike.

[MikeB12]

thanks for testing that wfo.. could have saved myself some work. lol... shoulda just deleted the old core and restarted the client... oh well, I'm on all console clients now...

[Shadowtester]

One thing about the new version of core_11 (v1.15) it will give you more ppd but it also produces more heat and if your card is maxed out on the over clocking you will most likely have to step back at least 1 step to keep it stable.

[Kondik]

Thanks for this echo Mike will try it at home, Hope I'll see stable 8.000 PPD +
As for the heat the card didn't hit it's 60's still good

[Marvin_The_Martian]

Thanks Mike, I could need a ppd boost lol

They always do, deleting current core and letting it auto download the new one is standard policy?

[ThunderDuck]

Thanx Mike I can use a few more ppd.

Really. Will have to try that. Thanks!

[Loony]

I just deleted the old core and downloaded the new one!

I also deleted my work folder just in case; is that needed? Will it resume in the middle of a WU if you download a new core?

Most of the time it will, but to be safe it's always prudent to do it between wu's ( eg run -oneunit and delete the core once done so it can auto dl the new core when you get a wu which requieres that core ).

[Shadowtester]

It will resume in the middle of the wu you do not need to delete the work folder if you do that it can not resume it will have to start a new wu and you will loose any credit for the work you had done on that wu.

Edit additional comment

What Marvin said about using the -oneunit flag to complete the current wu and then delete the core and remove the -oneunit flag is the safest way but for most small core revision you can get by with just stopping and then deleting the existing core and letting it download the new version. If its a new core not just a minor revision I think I would do the -oneunit method to be safe.

[Loony]

It was only around 15% so it's no big loss. I was just curious for next time.

My 8800gs is pumping ~4600ppd on project 5015 with 1700 shaders. That's about the same number. The temps are about the same. Ambient is a little higher right now so it's hard to tell.

[Sparky]

Well my 9600GSO got the new core, went from about 4900 PPD on 5016 to 5250 for a 350 PPD increase. Not bad for just downloading a new core
Will do this to my 8800GT next later today when I have time and it isn't halfway through a unit, I don't want to risk losing one at this point.

[Marvin_The_Martian]

It will resume in the middle of the wu you do not need to delete the work folder if you do that it can not resume it will have to start a new wu and you will loose any credit for the work you had done on that wu.

I could look it up if you doubt me but there been reported and confirmed cases on which a new core would not like to continue a wu in progress, 100% sure on that. There mostly isolated cases though but still I would say be prudent and be safe. If you have to choose between doing a mid wu change or having the client run overnight/weekend with an older core I'd say take the risk as the gains are usuaully big enough to warrant loosing a single wu then, but in other cases I would definetly use -oneunit.

I would agree the -oneunit flag method is safest however I had asked this exact question in the Stanford Folding@Home beta testers forum when FahCore_11(v1.13) came out and was told by one of the mods and a Pande group member that I could just stop and delete the existing core and restart the client that it should download the new core and continue where it left off. I then did that for (v1.13) and (v1.15) without any problems.

So in conclusion does it work and is it safe?
Answer yes it works most of the time however the safest method to ensure you do not loose any work would be to use the -oneunit flag let the current wu end then delete the core remove the -oneunit flag and restart the client and let it download a new wu and if a new core is needed it will download that as well.

[road-runner]

Got about 400 to 500 ppd boost myself, thanks for the info...

[Sparky]

OK I know this isn't nvidia, but I just tried deleting the core on my ATI client for my 4870, which previously would just EUE constantly. I got core 1.17 downloaded, and now so far it isn't giving out EUEs right away and at 4% it is estimating 3334 PPD and gradually increasing. Also, CPU usage is lower too, no longer using a whole core of my quad but around 2/3 to 3/4 of the core. Hmm, interesting. Might be able to run SMP and this client on my main PC now if they fixed the stability issue, that would be nice. We'll see how it plays out and whether it actually finishes a unit or not.

Confirmed also. Actually WOW. Went from 1min 17sec to 1min 9seconds. Server 2008 x64, 8800GTX, 1693Mhz Shaders.


Thats 6019 ppd rate.!

I'll temporarily stick this thread. THis is a significant increase.

[MikeB12]

just noticed fah forum has new threads about the new core from yesterday.. I'll add these to the OP.
core 1.15 http://foldingforum.org/viewtopic.php?f=52&t=6203
core 1.13 http://foldingforum.org/viewtopic.php?f=52&t=6182


I kinda stumbled into this new core this morning by accident playing around and converting my clients to console clients, and they dl'ed a new core as a fresh client install. I guess if I would have visited the gpu section of fah forum, and read those threads, I could have saved myself some hassle of swapping client installs and confusion.. I'm not a frequent flyer of the gpu section over there since I never have issues with the gpu client. anyway, I'll edit the op and add those threads.

[road-runner]

Went from 5316 PPD to 5841 on my 8800gt...
