Modified SETI MB CUDA + opt AP package for full GPU utilization

[Slawek]

time to OC my SP unit ;P

or buy faster GPU like 260 or 280


Now BOINC computing AP  to

[Raistmer]

temp 63 celsius stable at any freq

Fine, thanx. Collecting runtime statistics now then will OC

[Slawek]

i need info for my 8600GT what shader clock max for this card ?  and safe temp.

It's seems now time for searching some GPU OCing forums I need that info too About temperature - look at Devaster's post.

Has anyone tried multiple cuda enabled cards plugged into a single system yet?  Like 3 or 4 PCI cards in a single system.

Yes, I read at least two such reports already. Look om main forum thread with same name as this one - there is nice picture (snapshot) of BOINC manager state for syc system (2 cores and 2 GPU all working together on SETI AP + CUDA MB)

Nice, so it looks like a nice 4 slot PCI Express board with 4 GPU would be a crunching monster,.

Now what about GPU benchies,  4 9800 GT can be had off Newegg for about $100 each, or 980 Gtx for $169 or better yet GTX260 for about $229 each
Add a MSI 4 slot MB for $129, a nice quad core AMD for $119 and you would be in the super computing business.

Aha, and liquid nitrogen or helium better for cooling system
Although for "Ultimate cruncher" I could chose i7-based CPU instead.

3 X the new GTX295.  6 GPUs.  296W per card @ full load.  soo...900w just for 3 cards.

Curious if there is a standard power supply that can actually run 3 of these beasts on a 1366 board???
Takes (3) 6 pin + (3) 8-pin power connectors.

It would make a nice room warmer for cold winter months though.

Is there any way to combine AK for CPU cores with CUDA GPU app? I rarely get AP workunits, so AP/ MB CUDA often would leave my cpu cores idle...

No way still. Try to use SETI/Einstein combo for this moment.

pfu i try 178.28 180.60 180.84 driver from nvidia X64 windows xp but just crunch some work units with the gpu cuda and then all units goes error
what is wrong here

use the modifed seti mb cuda + opt ap

i try and boinc 6.4.5 and then 6.5.0 same problem
and even the boinc tell me the unit is success but when i go to the web site i see there is an error in all units
v_BaseLineSmooth (no other)
            v_GetPowerSpectrum 0.00016 0.00000
                   v_ChirpData 0.01016 0.00000
                  v_Transpose4 0.00387 0.00000
               FPU opt folding 0.00170 0.00000

all unit is that problem

[The Grinch]

I got on x68 BOINC (6.4.5 and 6.5.0) same error!
On my x64 machine i have CUDA don't get work ...
I think: it's very BETA

The only projekt thats work fine is folding@home (for ATI and nvidia)

[Raistmer]

Yes, it's very beta indeed.
If it can't work on your host it's better to refrain from SETI CUDA app till next, more stable release. And continue with AK8 opt app for now.
