foldingathome doesnt work

dragonajie · 2006-10-12 16:15:24

Hi,

foldingathome doesnt work. the file /opt/fah/FAH502-Linux.exe wont execute. anyone having same issue?

Kenetixx · 2006-10-13 08:09:58

if its an .exe file it will not execute, that is a windows file

Folding at home really starts a exe file under linux.

dragonajie: Be sure to start foldingathome as a daemon, you can't run the exe directly

# /etc/rc.d/foldingathome

If it starts properly ad "foldingathome" to the daemons in /etc/rc.conf.

If you did all the stuff written above and it still doesn't work: Could you provide a little more info? Error messages or the like? Your f@h configuration?

Couldn't start folding@home manually under Arch 64, so installed it the way Sigi wrote. But it won't start

# /etc/rc.d/foldingathome start
/opt/fah/FAH504-Linux.exe: Aucun fichier ou répertoire de ce type

Same stuff than when started manually (FAH502 as well as 504), even when :

$ ls -l /opt/fah
-rwxr-xr-x 1 kozaki users 250964 2006-10-15 13:41 FAH504-Linux.exe
-rwxr-xr-x 1 kozaki users    129 2006-10-15 13:44 client.cfg

The foldingathome .exe file is a x86 binary. It won't work in Arch 64 unless you use chroot or something similar. That may be the problem here.

kozaki · 2006-10-17 11:01:35

Allright then we have to use chroot to run folding@home
Ha ha ! guess I was fooled because I get used to launch it under Windozzz 64 after having configured the launcher to ru in Compatibility mode.

dragonajie · 2006-10-18 02:01:19

Thanks for the responses guys.
I checked out their website, apparently they are not planning on a 64-bit client at least until 2008 (!!!) so i installed it in 32bit chroot, and placed

dchroot sudo /32bit/etc/rc.d/foldingathome start

in my rc.local so it will get started every boot time.

i sure hope they will come up with 64-bit client sooner when they realise that 64-bit is already nearing mainstream.

Stanford is currently Beta testing an SMP 64 bit Linux ( and Mac OS X ) Folding @ Home client !
Macaholic is running it on a Quad core 3.0 GHz Mac G5 , processing a single Work Unit on all four Cores !
it's a 1210 point Tinker that finished in 21.1 hours !
57.3 Points Per Hour !
:shock:

dragonajie · 2006-11-09 02:43:18

Hey this is good news! when this goes out i will have one less application to have to run under chroot. w000ttt11!!!

Pick2 · 2006-11-14 05:45:35

The 64 bit SMP Linux client is released into Public Beta !
http://forum.folding-community.org/ftopic16812.html
They recommend 4 cores for now , a few problems to work out yet , you might want to wait a bit
A few are running on Dual Core Mac OS X Boxes ......
They say they are going to do a 32 bit Linux SMP client soon.
Exciting times for We Folders

I just Fired up a new Opteron 175 Blade last Saturday 8)

Beta fah5 binary for SMP client (x86-64 bit only) is available from their download page

We are also releasing another type of client: the Folding@Home SMP client. SMP means "Symmetric Multi-processing" (...)
The goals of the SMP client and the GPU client are similar: in order to tackle many of the problems of interest (especially related to protein misfolding and aggregation, such as in Alzheimer's Disease), we need to not just have lots of computers participating, but we need results returned more quickly so that we can simulate trajectories of sufficient length. Right now, we achieve this by running for many months to years (indeed, our first Alzheimer's Disease simulations ran for almost two years straight). That's where the SMP and GPU (and PS3) clients come in. They give us considerably longer trajectories in the same wall clock time, allowing us to turn what used to take years to simulate even on FAH, to a few weeks to months.
Moreover, the SMP and GPU clients are complementary. The GPU client can greatly (~30x) speed up a specific type of calculation (implicit solvent calculations), whereas the SMP client can lead to a 4x speed up over the complete range of calculations we need to run. (...)
Our goal is to apply this new technology to dramatically advance the capabilities of Folding@Home, applying our simulations to further study of protein folding and related diseases, including Alzheimer's Disease, Huntington's Disease, and certain forms of cancer. With these computational advances, coupled with new simulation methodologies to harness the new techniques, we will be able to address questions previously considered impossible to tackle computationally, and make even greater impacts on our knowledge of folding and folding related diseases.

This is a beta release and we expect that there will be several bugs, flaws, problems, etc. To minimize problems, we have been testing the client and cores extensively in house and they run well there. However, it's our experience that running in the controlled setup in our lab and running "out in the wild" are very different situations.

Note that it may not be as simple as launching new fah5 binary. From Folding-community forum, i can see
fah5 binary itself is 32 bit : the guy on Ubuntu Edgy x86_64 needs to install the 32bit compatibility package "ia32-libs".
Anyway there's no solution yet for single proc x86_64 like my amd 64 ?
Will give fah5-beta a try just in case.

EDIT
Well, that was worth a try :
$ ./fah5

Note: Please read the licen
se agreement (fah5 -license). Further
use of this software requires that you have read and accepted this agreement.

Now 3 questions for you guys.
- will it works as expected by folding team (SMP) ?
- will it runs on custom kernel recompiled without SMP for single core machines ?
- wonder what kind of flags they're using when building this binary.
