I've reuploaded archives, it appeared it indeed had cudart.dll dependancy.

Got it running again

Works perfect!

And gave me a new high score

How much did you have to pay for all that shit o_O
and how much power does it need while working?

For this box alone not sure, $400 for each 295 X 3, $160 for the 9600GT, the LS-1200 PSU was $230, orginal system, motherboard, cpu etc was $2000, not including monitor and stuff.

That's weird.. No errors or anything. 0.B just won't work out of the box...
Won't register my card, and just run CPU cracking... :/

Could you try to update your display drivers? What's your GPU?

8800 GTS

Actually.. Following up on that.. Old Bars won't work either..
Will check drivers if I can figure out how (Opening NVidia Control panel )

EDIT: 185.85

EDIT: Friend has 190... I'm getting newer

EDIT: Got 191.07 now.. All fixed...

Is there any reason that speed varies so much between cores? Those systems were all idle otherwise.

Well, you might need to wait a little, it calculates averages among some 10-100 seconds of execution.
Also, GPU thread is running on one of these 4 cores, and it eats some cycles to prepare work for GPU.

Yea I usually wait a bit as well, tends to get a little faster as it goes..

By the way finally broke into the 5's

There is a problem with a time estimation, when I use:

gpu_time=1000
charset=aA
min_len=16
hash=1b0e9fd3086d90a159a1d6cb86f11b4c

What kind of a problem? Screenshot and details please

As you can see below, ver 0.B cannot show a correct time required for a calculation.
A hour value is changed every second, for example, like 2, 21, 18, 9, 16, 19, 6....

Could you try this with length 15?

[protter]

Sure:

Code: Select all

gpu_time=1000

min_len=15
hash=1b0e9fd3086d90a159a1d6cb86f11b4c

This happens because days left is more than 2^31. I guess if days left is more than 2^31 then ETC could say "NEVER" or have it state time left in millions of years.

BarsMonster, what is the max supported amount of GPUs for BarsWF? I just order a new motherboard and it should allow me to use more than 8GPU's. I heard that there is a driver limit of 8 but I don't know anyone that has had more than 8 in a single motherboard to test that out. Also I've heard IvanG's say his ighashgpu only supports 8 cards as well. But inside pros Extreme GPU bruteforcer is now supporting mulit GPU's and he has said his software can support up to 16. In anycase I I guess I'll find out later this week what the actual results are.

[IvanG]

Also I've heard IvanG's say his ighashgpu only supports 8 cards as well.

It's not true, actually. I haven't heard about systems with >8 GPUs so I have no idea will ighashgpu works with them or not. But there no hard limit of 8 GPUs in source code, AFAIR I used value like 32, so if CUDA layer will reports 16 GPUs it should handle it properly.

However, I've already linked somewhere here quote from nVidia's guy about systems with >8 GPUs, it's something like "good luck finding BIOS which supports such config".

I guess you'll got several problems going this way

[protter]

good luck finding BIOS which supports such config

Hmm... actually it is possible to write BIOS by yourself

[IvanG]

Hmm... actually it is possible to write BIOS by yourself

Well, it's possible to make hardware MD5 cracker with FPGAs or even better -- design in VHDL and order 40nm MD5 crack specific chips... But somehow I have feelings that nobody will actually do this .

There are problems with ATI GPUs at driver level -- not possible to use more than 4 of them. And still nobody found solution for this by rewriting ATI drivers. It's still impossible to normally activate more than 5 nVidia GPUs under Vista/7, again drivers issues and, again, nobody "hacked" the drivers to solve this.

So I really really doubt anyone will care about writhing his own BIOS to support specific hardware setups. Just too many time required and you must be very experienced with low level I/O.

[D3ad0ne]

- Perhaps this is why I thought you mentioned 8 GPU as a max.

The motherboard I picked up is the asus P6T7 WS supercomputer - http://promos.asus.com/US/Newsletter200 ... /P6T7.html it has X58 / ICH10R chipset, and an additional nforce200 x2 chipset to add more PCI-e lanes. Primarily targeted for folding@home type users. At least I should be able to get 4 GTX 295s in this one, unlike the P6T/SE version I currently have only supports 7 GPUs total.

Bars do you have any hard limit set in your software?

Current limit on BarsWF side is 128

Michail, you think positive and look deeply in to the future, ehh ?

No. just a visionary guy, i guess.

[Sc00bz]

How does --gpu_mask work with 128 GPUs?

[BarsMonster]

How does --gpu_mask work with 128 GPUs?

Everything over 32 is always enabled

[Sc00bz]

Then why is there a set limit?

Array length?

Just my guess
