Ultimate Guide To Folding@home

Twice now since I've been using F@H, it's crashed taking hours of CPU time with it. The first time I lost about 71% of a work unit, due to a communications error with the server:

"[06:21:45] Completed 355000 out of 500000 steps (71)
[06:33:02] CoreStatus = 1 (1)
[06:33:02] Client-core communications error: ERROR 0x1
[06:33:02] Deleting current work unit & continuing...
[06:33:22] - Preparing to get new work unit...
[06:33:24] + Attempting to get work packet
[06:33:24] - Connecting to assignment server
[06:33:27] + Could not connect to Assignment Server
[06:33:27] + Could not connect to Assignment Server 2
[06:33:27] + Couldn't get work instructions.
[06:33:27] - Error: Attempt #1 to get work failed, and no other work to do.
Waiting before retry."

Which prompted me to stop using it. I retried it the other day, got one WU completed. My PC crashed again today, and no surprise, F@H lost its WU again:

"[16:33:30] Completed 480000 out of 500000 steps (96)"

:(
 
Me too.. some time ago.

Didn't know there was a certificate for it.. thanks!

dose eny1 know about overclocking ?How dose it work?do i need a prog?to check my cpu heat level do i need a senser?sorry to ask so much Q's but i want to learn about this stuff. :D
 
I was looking over the team statistics, What I was wondering about is the pts. I see there is a page that you can goto to see what the worth of a package you are doing. How do you get these pts is it after you are done the package or every so offten? Im not really worried about the pts but it would be kool to see how I stack up against other ppl.

One last thing to ask, then I will stop asking so questions.

I was think about how to get my pc fold faster. I thought about running F@H in safemode, So I did. The #'s are hard to read and I only did this for a hour but it seemed to be a bit faster. Could anyone else see if this could work or not.
 
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 :)
 
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))
 
the points are credited when you return the WU to the server. but it my not show up on the stats for a wee bit. to give it time to update.
it probably will run faster, but maybe not alot, since it safe mode will be using less resources. but prob isnt worth it, since u gotta restart to use it/

try updaating your graphics driver,

has it always done this? or just recently?
Click to expand...
Nothing wrong with my driver.
I happened this morning after my modem resets himself.

If i leave the Icon alone it's ok. Right-clicking is allowed, left is not.
As long as it's running it fine by me.
Hoovering over the icon gives all the info i need anyway.


Thanks for your help Ivy. ;)
 
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'm sure more people would sign up for this if they knew about it.

Another group (newz.dk, team number 34688) were moving along at a rate lower than our group, in fact we had passed them. They were getting just under 1000 points per day. But they did something a few days ago and they now have over 800 processors and are now getting just short of 20000 points per day, and rising!

I feel sure that if more of our users knew about Folding@Home they would happily take it up. We need a link ON THE FRONT PAGE - something as simple as that could bring in loads of new participants.
 
if anyone has probslems using the -forceSSE command with amd processors, there is a beta gromacs core which fixes the problem. it will be automatically distributed soon if you dont want to use a beta core.

http://www.stanford.edu/group/pandegroup/folding/beta-core/

to install, download the new core. close folding@home, and put the new core in the f@h folder, then run f@h again and it will use the new core for gromacs WU's
