Multiple F@H-GPU clients on multiple ATI cards

**Steensen** · 11-03-2006, 09:46 AM

Just reciewd my X1950XTX, and then went to DL the GPU F@H client, and then i saw a new version 5.91, and a FAQ multi GPU link.

So for those of you running two X19xx cards there is now hope foreward.

http://fahinfo.org/gpu/multi_gpu_howto.html

This FAQ doesn't say anything about, if it is possible to run two GPU clients on a CF setup, so if anyone can test this, it would be great.

Well its a step in the right direction for those of us who do DC projects. Im not a F@H guy, but there is light at the end of the tunnel.

Is it just me or has AMD/ATI just found another way to add value to old hw

Though if the G80 comes out doing stream processing for F@H...X1950XTX will get owned by more than 2x performance.

umm Perkam the reason that the 7900 isn't used for F@H is because they can only do 24bit Floating point. You need 32bit floating point for scientific calculations

Hence why i pointed towards G80 not G70

Actually the 1950XTX will not get owned by a G80. If anything it might be 20% better but not the kind of owning I am guessing that you are thinking.

Yields on GPGPU are dependent on the software that utilizes it. If F@H guys worked with NV as hard as they did with ATI, I'm sure G80 would be ahead by a bit.

Apples to apples here gentlemen.

Ive heard rumors that the 8800 might not run f@h, cant remember where i read it but it hinted that they might not let it run on the 8800. (thats not saying it cant)
It needs to think you have 2 screens so it wont work on xfire, if i have time i will get round to trying it out, need to find a second screen though.....

**Timmay** · 11-04-2006, 02:13 AM

The G80 can run F@H but will still not run it as well as a X1950XTX

Man OC'd watercooled x1950xtx crossfire and phase cooled kents would be like having a small DC farm in one case

My 3000+ can't fold...so why should anyone else fold !!!

WHINE WHINE WHINE !!!

Think of it as a benchmark program for forums.

its definately not going to help cure cancer or anything with that attitude.

The reason people fold is for the stats and competition. They have been doing it for years and there have been no results. Maybe in a few more years they will get something done but as of now nothing is coming from it.

That's like describing Cancer Run For the Cure annual marathon as "It's for buff people that like to show off...but they haven't cured anything yet"

Quite resentful considering some of the dedication we've seen. I will admit that some of the stuff with Dr. Barker and XS did get very screwed up...but you can't discount ALL projects on the demerits of a few.

DR. Baker Basically said that we were not the type of help he wanted. So it is his loss, not the community's

**Pillo-kun** · 11-04-2006, 08:51 PM

Returned home after a quite a misserable partynight. Maybe I´m to old now and find going out and drink and such too boring nowwadays, who knows? When I saw the that somebody(not mentioning any names here ,hehe) has edited my post i bursted out in laughs..Thanx ya just saved my night, hehe.

Well i still dont see the point with folding. I rathed turn my pc off than fold to try and find some cure for a disease and not getting any credd for it. Even if i did get a thanx from a million persons i would not be happy cus it would not be my doing. Just a program and a machine doing what they are told to do.

I have a friend that does real research on viruses and such at AstraZenica(never ending studying), and he said to me once that this kind of sysems are more or less worthless but still there is always a possbility that theirs folks and supercomputers have missed something small that folding can provide with, but that is a very small possiblity. His words.

I know this seems hursh or harsh, eh whatever. But this is how i see it. And my 3000+ being to weak? Well i dont see any reason to upgrade yet, I feel that if ya wanna paly games at max ya just need a reasonable amount of ram and a good videocard.

well time to go to sleep if i can.

**[cTx]Philosophy** · 11-04-2006, 09:06 PM

Your 3000 isnt to weak...
Points isnt the only reason we do it, its for the science behind it..
And your friend is wrong, every little pc helps alot more than one human can..

Yeah the G80 has the same performance in this regard as the 7900 does... and so will not be able to beat the X1950/1900 in performance in this situation.

**awdrifter** · 11-05-2006, 03:39 AM

Didn't the human genome was decoded by a distributed computing project like F@H? So maybe we aren't seeing any results now, but in 10-20 years, we'll definitely see some results from all this computing. But with that said, I wouldn't buy a new comp or even run an old comp dedicated just for F@H, that's too extreme for me. I just let F@H run on my comp when I'm downloading or just web browsing. Too bad my vid card is too crappy for F@H, otherwise I would run a copy on my vid card too.

**Scimitar** · 11-05-2006, 05:02 AM

Simulating protein folding is a process. The cure for Cancer or any other disease will not come overnight, but misfolding simulations done by distributed computing ARE a valuable resource towards that goal.

True for most of us.

False.

I wouldn't call 45 peer-reviewed papers no results. Sure, they haven't found the cure for cancer. But things don't work like that. Their primary mission is to understand protein folding which in turn may help finding cure for a bunch of diseases.
