Ultimate Guide To Folding@home

Thanks lynx.

If I do this, then the only difference is that I will have 2 separate wu's going? It will not use more of my processors capabilities? Sorry, this new computer setup is new to me and I want to be sure I am using it to it's full potential.

I am kinda confused about the HT technology. Do I really have 2 separate processors or does everest just report it that way?

I can see 2 separate cpu's listed and how much power is being used by each, however according to HP I only have 1 processor.

Anyway, thanks for you help. Hopefully I can use this computer for good as well as evil;)

I don't know what's happening recently, but FAH is screwing my machines.

I did a full reinstall of XP on my newest machine, now it usually hangs after a few minutes with FAH. It isn't overclocked or anything. If I start FAH and then stop it, it still hangs after a while. But if I never start FAH then it doesn't hang.

My old machine has run for 2 years without hanging. I installed Linux on it the day before yesterday. If I run FAH it hangs within an hour, even if FAH has been cancelled. Without running FAH, it has been up for 30 hours.

Something has obviously happened with the type of projects I am currently receiving (which may have changed because of the reinstallation?), because I never had hanging problems before. I'll keep trying new projects occasionally, but until these problems go away, sadly, I can no longer commit my machines permanently.

I know it doesn't help, but Rocktron and I both had similar problems. They started last Thursday.

I had serious problems with a WU from project 524,
locked up the machine 3 times in a row, every time restarting at 0/500 :angry:
Deleting the work-folder doesn't help as the F@H servers just hand out the same WU over and over again.

As a temp solution I made a backup of my WU several times a day using WinZip.
Shutdown F@H first before zipping it, as F@H writes "shutdown in a normal way" to disk.
Failure to do so (as in a lockup) will restart your WU @ 0/500 when you use the backed up files.

Now what is the cause?
The only thing I can think of:
I used a proggy "CWShredder" mentioned here on the forum. Could it be we all used the same proggy? :unsure:
 
You've only got one processor, but some parts of it are duplicated. These are the simpler components which don't produce much heat, such as the main instruction path, the arithmetic unit etc.

It has to report that it has 2 processors so that windows can schedule it to execute 2 tasks simultaneously. That effectively means that with two tasks which for the most part only use the duplicated parts you can get more performance out of the chip.

Unfortunately F@H mainly uses parts which aren't duplicated - the MME stuff and the FPU. These are complex units and produce large amounts of heat, which is why they aren't duplicated. So although you could have 2 copies of the program scheduled to run, in practice they would be waiting for the shared resources to be free.

There's even a down side to HT when you want to run another program, even with only one copy running. Windows sees that it has a spare "processor" which can run your prog, it doesn't know about the shared resources. So windows schedules your prog and doesn't bother interrupting the other FPU/MME intensive prog. If your prog uses the duplicated parts there's no problem, but if it uses the shared parts then it runs like a dog.

Nice one Intel - how to slow down our systems by not thinking out the problem. Nothing new there then. :dry:
 
Woot!!! i needed something to keep my cpu warm and here it is thanks guys practicle and i am yhelping poeple wow very nice... it will vae to compete with muy other one that is tryong to calcuate and find other alien species... on other planets... :01: :lol:

ohh ya 2500+ and 2gigs ecc...
 
I think I'll just pause my hard earned little weeny WU until the server comes back up.
If I'm gonna get stuck with these damn Tinker units at least I want credit for them.

Lamsey...last I looked I was still 1000 points ahead of you.
I believe that I can mosey along in this lane for a while longer before you are inconvenienced. :P

Just to show you what we're doing is child's play. :unsure:

It makes me humble.
Over at Sudhian.com a guy named MarkF build a 'Folding Farm'.
A rack totally filled with stripped boards, with a single goal: Folding.
Every floor in this rack carries 2 boards.

(Pics are shamelessly nicked from Sudhian)

Now these things are AWESOME!

what are they? :unsure:

Just kidding. :rolleyes:

I'll make a KLF forum sig as a supporters banner type thing tomorrow which people can feel free to use.

By the way, can you explain gromacs? ..

I installed the installer linked to in the first thread, set username and left running ... now it shows:

17/400 ..... 4%

Am I doing everything right or is there more to it?

go to the second page there is a guide on it :D ;)
 
30,000 over here, :)

also team just passed 6000 wu mark.

ive taken 2 of my machines of full time folding for electrcity use, which isnt much as there laptops, and the noise, so they get put off at night now. :(

Just got me this morning a "Protein: p858_p53dimer858"
It's 160 points worth, and takes 25 minutes to complete a frame
----------> almost 42 hours to complete this WU
----------> 160/42 = 3.84 points per hour!

I want more of these ! :rolleyes:

I've got that one on my main pc, and P859 on my XP1700. That one is going to take about 56 hours, so there won't be any changes to my stats for a couple of days. :(

On the up side, a friend is going to GIVE me a dual Athlon mobo and processors (1 Ghz I think), then I will really be able to raise some dust.

Btw, anyone got any info on ocing dual processor systems? :lol:

At the top of the list on the stats-page you'll find some cheaters using more than 1 CPU.

just coz ive got more than one pc doesnt mean im a cheater. :edit: we seem to be slowing down a bit now, we need more folders. :D

i think 7th should put a subcontent on the main page. get more people in. since we are higher ranked mor epeople will be interesed i think.

go team 34905
