Ultimate Guide To Folding@home

What is gromacs?

Gromacs is the new folding core (FAHcore_78.exe) GROMACS provides extremely high performance compared to all other programs. For some calculations, gromacs affords benefits over the current code in FAH (the current code is based on Jay Ponder's Tinker), especially a great speed increase (perhaps up to 10x-20x). This will substantially increase the power of FAH for many calculations.

some ppl say that it actually gives you more points as well...so its a WIn WIN! situation :D

Streaming SIMD(Single Instruction Multiple Data) Extensions

Processors & applications that do not use SSE process one data element in one instruction, a processing style called Single Instruction Single Data, or SISD. In contrast, processors having the SIMD capability have the ability to process more than one data element in one instruction. In other words the processor can work harder with the same two hands (if you get the metaphor). Using SSE requires support from the application, the operating system & the CPU.

Processors that have SSE are as follows..

Athlon XP
Duron 1 GHz & above (morgan core)
Pentium 4
Pentium 3
Celeron 566 mhz & above (coppermine & tualatin cores)

Processors that do not have SSE are as follows..

Duron 950 & below (spitfire core)
Athlon (K7, K75, & Thunderbird cores)
K6-3
K6-2
Celeron 533 MHz & below
Pentium 2
Pentium
All Via/Cyrix CPU's

Anything released before the processors listed of course does not have SSE.

Any version of Windows after '98 supports SSE (95' may just not sure). Any newer Linux distro should have support as well.

The Gromacs core also uses AMD
 
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?

88 points in it

are you going for 3rd? [/b][/quote]
Well, yourself and IC have three CPUs; I know yours are slightly better than mine, and I don't know about IC but he seems to do well, so I'll be hard pressed to catch up with you. I'll overtake Clocker at some point though :devil:

I had to format my comp the other day so I lost that big juicy WU :(

bummer. i dont think ive lost any WU so far anyway.

ive also just added another machine, a amd k6-2 500, with 256mb ram. running a little each day. running the genome@home, which is now just folding WU without a deadline, since its a slow machine, and not on alot.

Woot, finished my first WU, was a 1000 one, only took like 8 hours on my athlon XP 1900, but yet the I'm doing a 2500 on my Athlon XP 3200+ and I'm still at 934/2500 after 24 hours???!!!???

Lots of things affect how long a particular wu takes, not just the number of steps. You may have a very simple molecule with 1000 steps, or a very complex molecule with the same number of steps. Obviously there are a lot more ways a complex molecule can fold, so the process takes much longer. But you should also get a lot more points for the complex one.
 
if your machine has sse commands, then go to your startup folder, and alter then folding at home run command, and add the -advmethods switch, this should give u mostly gromacs, which use optimisations, where as the tinker core doesnt, thats why they are slower.

Yeah, I believe so. I can see it go up to 65% (when the task manager first opens) but FAH only uses 50% of it.

Either way, even if it is only 50% it is still a lot faster then my old one:)

Ok, from what I can tell, I have 2 processors. This is what the everest program tells me anyway.

I would like to set up 2 instances of the console version of FAH but cannot figure it out. This is what FAH says:


**Yes, you can. Additional processors must run the console version
(with the "-local" command-line argument if run on Windows).
First, make additional directories for each processor and copy
the FAH Console executable file into each. Then configure them
with the -config switch, filling in settings for each.
It is very important to make sure that under the "Advanced Settings"
option each copy is given a unique machine ID (from 1 to 8).
The first copy will default to a machine ID of 1, so additional
copies should be given IDs of 2, 3, 4, etc. Each may then be run
out of their installed directory, using the -local switch on windows.**



Anyone one else do this? I cannot figure out how to name each version. Where is the config switch? Where is the advanced settings in the console version? If you know how to make this possible for an idiot like me I would greatly appreciate it.

Also, does it matter where I make the separate directories? Or can I make them both in the folding@home folder?

Thanks

go to the second page there is a guide on it :D ;)
 
Ahh, thanks for clearing that up for me Lynx, it just seemed rather odd that it was taking longer to work on a faster processor. lol

After the first WU, they seem to be going much faster now. The Gromac tags really do help alot!
 
I've joined too and will let this run at all times, unless i'm gaming. I've also had UD Agent running for a while now which helps in cancer research. My computer is running 24-7, and i'm not even at it most the time so why not use up some clock cycles.

Well done jaigandhi5, for promoting this.


EDIT :- Athlon XP 2400 = 2gHz (let's not get into that one, ok :lol: (the geeks here will understand))
 
and just to prove how much this helps look at the team stats page...

i used to be in 25th or 26th place and look at me now..... ;)

im geting like 4WUs done in 24hrz sometimes even 5WUs :)
