Folding@Home: CF Official Discussion Thread

Great! Each person folding helps out, both for Stanford and our team.

I think I have everything running now, with one core for GPU, one for a CPU F@H. While I won't be having as many clients running, even this setup is better than I thought, PPD wise. Now I just need to figure out what's up with my graphics card that makes it tricky to overclock...
 
I'm in a Junior Achievement Program and they have a computer lab, 5 2.8 Gh P4s with 1 GB Ram each, and i talked with the coordinator, and she forwarded me on to the branch manager, but said that they do leave them on 24/7 and they do have DSL, so wish me luck...

I hope you don't have them fold for you :P Make a different username...

Goodness no, i don't want to get passed by myself!

Whatever. Suit yourself. So far, people have only used computers that they have built, or they own for their own usernames. I'll have to start asking others to fold for my username if you have them fold for you!
 
Jet, the AIW X1900's I've read are not good overclockers. Which, with all of those extra things on the PCB, I can understand it. Perhaps with an aftermarket cooler, if they make one for it.
 
Heeyy...

I think it's perfectly fine if people fold under their username on other people's PCs. That way, it stimulates competition and brings our team (which is what matters most), to a next level. Feel free to use your username for all your PCs as well as other PCs. It's not about how many PCs you got on your side, but how much you can contribute to the team :)

I have read of people who have gotten them up to 700/700. I think the driver 6.10 isn't as good as the 6.5 driver. I think I will change back eventually. Before I changed the driver, I got up to 600/685, with no voltage increase.

F@H didn't count my last WU :(. Oh well, I'll be in 6th until tommorrow :)
 
Heeh

Heya,

I think there are some issues with the stats on F@H on extremeOC. Every team I checked out is experiencing a substantial drop in the amount of points/day and as Jet suggested, may not be getting the points for it. For me it's fine and I am sure that it will turn out just fine.

Oh

jan did you get my PM over the HT question
Click to expand...

My bad,

here's the answer:

What about hyperthreaded (HT) CPUs?
The SMP client was originally intended for multi-core CPUs, which generally do not support HT. For machines with 2 physical CPUs, we do recommend enabling HT for the SMP client as this presents the operating system with what looks like 4 logical processors (and our SMP client is intended for 4 processors). If you have 4 physical CPUs, we do not recommend using HT, as this presents the operating system with 8 logical processors, which will make the SMP client run inefficiently (especially since the logical processors coming from HT run much slower than the normal ones).

Its funny, with one driver I got 1:14 (hh:mm) per percent, instead of 0:12 that I usually get. I was 55% done with one, and then I got a EE because of tampering with the clocks. I just need to be patient... :)
 
I havent been folding for awhile because something went wrong with my desktop computer but now i am getting a laptop sometime next week so i will be able to start folding again but i wont be able to fold 24/7 like i used to.

No problem. The main thing is that you are still helping out. We all appreciate it.

Now here's an update on the stats:

Date of last work unit 2006-11-17 03:19:34
Active CPUs within 50 days 129
Team Id 44358
Grand Score 406242
Work Unit Count 2248
Team Ranking (incl. aggregate) 943 of 46572

JAN :D
 
I can't wait for 800th place :)

Just around 20 days more, and lots less if we up our production to what it was :D

EDIT: 400,000!!!

Im still not sure on this, my research suggests that on single core rig, setting Hyperthreading can boast 20-30%ish.
However, if you try and run two instances of Folding@home on the same Hyper-Threaded CPU, they will both be competing for the same instruction units. This essentially means that each Folding@home instance shares its access to those instruction units. Overall a small performance gain is achieved due to the few calculations that can be run on the "spare" instruction units. However the end result is that the two WUs you are running complete in just under twice the length of time as a single WU would because of the afore mentioned instruction unit sharing.

on another note regarding smp, the new beta v5.91 will support SMP :D
http://folding.stanford.edu/FAQ-highperformance.html
2/3 down the above site said:
November 2006 The SMP client is now looking good enough that we are starting a more broad beta test outside of Stanford. If that looks good, we will move to a completely open beta test of this new client. The SMP client supports OSX/Intel natively (which means a major points boost for OSX donors) as well as 64-bit linux (with 32-bit linux hopefully to come soon). Windows support will come much later, as this is a very different architecture for porting than OSX & Linux.

another reason to move to linux :)

in the mean time, i thing that there is a slight improvement in running two instances on a single cpu with HT turned on.
