Ultimate Guide To Folding@home

We have had a few warmer days just now Rock.
Is there any chance heat is the problem?

Like in "Sun shining on your case" or,
"Dust and cobwebs on yyour heat-sink" :ph34r:

Most times when you delete a work unit you'll just get the same one handed out over and over.

Yeah it sucks, been there, done that..... :angry:

Close FD2, i found it out. Because of the heat i'm using CoolerXp and guess what?
They don't like each other. Stopped CoolerXp and Wham there it go's.

Spend 3 full days folding and no points were added. :angry: The bad thing is i did no work for the cause! :angry: :angry:

Oh well...

Thanks for the help guys
 
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:
 
As of client 4.0 there is a new switch: -forceSSE

Quote from: http://www.broadbandreports.com/forum/rema...22116~mode=flat
With an AMD processor, -forceSSE forces SSE on, -forceasm forces 3DNOW on and if you don't code either, you run with just normal processing. -forceSSE = fast, -forceasm = slower and no switch = very slow.

The -forceSSE switch forces an AMD processor to use its SSE optimizations. Use this switch only if SSE optimizations work well for you. If running the client under SSE optimizations causes too many problems, then switch to -forceasm, which will force 3DNow optimizations on an AMD processor. Seldom do AMDs have problems with 3DNow, but some do have trouble with SSE.

Quote from: http://forum.folding-community.org/viewtopic.php?t=6170
The assembly optimization for SSE is the code that occasionally pushes many AMD machines into unstable conditions. The parameter -forceSSE simply gives those who have demonstrated their machines are stable with SSE operations to regain the extra 15% speed boost that they had before the default was changed to 3DNow optimizations.

There are 3 types of code in the PC version of Gromacs: Unoptimized, 3DNow+, and SSE. How you invoke them was changed depending on the flags and the client version, but the fundamental code is still the same.

So, with the newer AMD CPUs you could use:

-advmethods -forceSSE


Fold on ! :)
 
1. What is FAH?
FAH is a distributed computing project, the purpose of which is to learn how proteins fold and misfold. By breaking down the process by which proteins are created we can find out what causes them to miscreate or misfold. The hope is that this will lead to future research that can help scientists come up with better treatments/cures for many of todays common ailments. But the most important part of the project is putting together an effective model of how to fold and unfold proteins with supercomputer power.

:) Thanks Lynx, your explanation seems plausible, I shall check it out to see if I can make F@H "pausable" again! :lol:

Ps. Good to see you moving up strongly...

Ok,

Now I added a second rig to the Folding-community,
this time folding for team 34905 !

This might be my only chance to kick Lamsey's ass....

I assume you've all checked the Team statistics, and noticed that Lamsey isn't leading by THAT much

btw i noe y bigdawgfox has so many WUs he went to his school...and borged LOTS of computer....

tht lucky guy has like P4s 1.7ghz at his school mine has P2 233mhz... ;)

damn borger....

its very easy to borg its like a .bat file and u just run the bat file and the cmd windows pops up does everything and the FAH starts up....the person wont even know tht u hav it running (runs with services)

theres a .cfg file as well which u config and put ur username and team number B)

one clickers:
Win XP, and WIN 2k
Windows 9x

get permission b4 u start putting this on floppys and going and putting em all over ur school or workplace u could get suspended/fireD! :ph34r:

hav fun borging

remember to edit the .cfg file
and put my name in it :ph34r: :lol: j/k

At the top of the list on the stats-page you'll find some cheaters using more than 1 CPU.
Click to expand...
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
 
I know, but sometimes by repeating the number, now and then and not just a link to the number, some members might then think, " I will try it too" untill they see lynx's and VB's scores of course..Perhaps there is a way of hiding them. :o

... Me myself, I know the number actually, it's 34905.
