Hi,

I'm using the new client, and I have found that I'm considerably much faster than normal Versions without CUDA support.

My PC Spec:
GenuineIntel
Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz [Intel64 Family 6 Model 23 Stepping 10]
+ 1* NVidia 8800 GTS 786 MB
CPU Sec: 6,703.24

Other Spec:
GenuineIntel
Intel(R) Xeon(R) CPU 3060 @ 2.40GHz [Family 6 Model 15 Stepping 6]
CPU Sec: 9,568.96

I don't know how good you can compare the both systems, but it's a big different's between the two systems.

One interesting point is, that the measuring of the floating points and such are higher for the XEON PC, so I presume that the Benchmarking are not optimised for CUDA yet.

kind Regards,
Matthias

One Q9550 core is of course faster than one of Xeon 3060, as the numbers say. New client doesn't give any speed improvement.
CUDA task actually takes about 200 seconds of CPU time ;)
You didn't tried SETI@home beta CUDA tasks yet?

Hm, thought I did... :)

To be hounest There's no good information how to get it to work with CUDA (http://setiweb.ssl.berkeley.edu/beta/cuda.php).
I do get the information that the BOINC Manager has CUDA and found the GeForce 8800 GTS as Coprocessor.

Maybe someone can give me a hint what to do?

You already have appropriate video card and BOINC 6.4.5, so you just need to install CUDA 2.0 drivers, if you haven't those, and then attach to project in the client using this adress, but it seems you have been attached already since I see 'volunteer tester' under your name...(?)

Hi again,

thanks for your information. I'm already registered there, but i didn't receive a task from there yet. What do I need to do, to get those Beta WUs?

If the pc you're trying to get WU's on has the CUDA drivers required, and is attached to the Beta project, with "Allow New Tasks" enabled, you should already be getting them.

If you post can post in the SETI@home Enhanced section of Beta there's probably more people there than at main that could assit you. If you're not able to post in that section then you should be able to post in the AstroPulse section.

---

You just registered there or trough BOINC? It probably don't know you did :)
On the projects tab you see SETI@home and SETI@home Beta Test as well?
If not, then attach to project via Tools>>Attach to project... and use the adress I gave. SETI@home beta test have its own message board.

All right, that worked.
but now I get the message Enhanced is not available for your type of computer.

Kind a hearts. :P

You're not first with 8800 who get this message. The program is too yellow.

It appears you need a CUDA capable GPU of 1.1+ certain 8800s can... some cant. Below is from GPU grid...

To bring some light into the jungle of chip code names, computing capabilities and shaders I created the overview below.

Since Cuda 2.0 has been made available in the middle of August this year, the project provides applications that are compiled with the Cuda 2.0 SDK.
Unfortunately Cuda 2.0 only supports Cards that have the compute capability of 1.1 and higher.
Cards that offer only compute capabilities at 1.0 level are lacking a hardware features (support for Atomic functions) that Cuda 2.0 relies on, hence Cuda 2.0 compiled apps won't run.

64 high clocked or 96 moderately clocked stream processors should be fine to participate and give results within a reasonable amount of time.

Cards that are red will not run the new applications that are compiled using the Cuda 2.0 SDK.
Cards in grey are able to run these applications, but are to slow and hence not recommended by the project.
Green cards will run the current applications without problems, if there is any it should be a software bug...


Computing capability 1.0 - it won't run

* GeForce 8800 GTX - 768M - 128 shader units

Computing capability 1.1 - it works

G84


* GeForce 8600 GT - 256/512M - 32 shader units

G86


* GeForce 8400 GS - 128/256M - 16 shader units
* GeForce 8500 GT - 256/512M - 16 shader units



G92


* GeForce 8800 GS - 384M - 96 shader units
* GeForce 8800 GT - 256/512/1024M - 112 shader units
* GeForce 8800 GTS - 512/1024M - 128 shader units
* GeForce 9600 GSO - 384/768M - 96 shader units
* GeForce 9800 GT - 512M - 112 shader units
* GeForce 9800 GTX - 512M - 128 shader units
* GeForce 9800 GTX+ - 512M - 128 shader units
* GeForce 9800 GX2 - 2x512M - 2x128 shader units



G94


* Geforce 9600 GT - 512/1024M - 64 shader units



G96


* Geforce 9500 GT - 256M - 32 shader units



Computing capability 1.3 - it works

D10U-20


* GeForce GTX 260 - 896M - 192 shader units



D10U-30


* GeForce GTX 280 - 1024M - 240 shader units



The information given is based on the following two pages and I'm not giving any warranty that I didn't understand all this completely wrong ;-)

There's a report that the Beta SETI@home Enhanced message board has been enabled for new testers without any Credit/RAC to post directly. Those of you already testing the Windows version may want to join in the discussions there.

Well I'll be waiting for this to be finalized and released. Looking forward to using my GPU:

G92
* GeForce 8800 GT - 256/512/1024M - 112 shader units

Linux laptop:
record uptime: 1511d 20h 19m (ended due to the power brick giving-up)

Really doesn't make me happy to hear this, because that was never mentioned on the starting website.

They should make it clear, so people could save their time and effort to get in the beta.

I'm not sure I understand what you're not happy about. Starting website? Do you mean the home page? I don't recall anything Beta ever being announced on the home page, and I don't think that should change. Beta should only be heard about on the forums and not advertised.

Make what clear? Anyone can get into Beta if they really wanted to. Everything blew up because of a casual mention by Matt Lebofsky when he was merely trying to announce upcoming plans and hoping to create a little bit of excitement - and I think he got more than he bargained for!

I'm not sure I understand what you're not happy about.

Looking at the opening post, Gunhed has an 8800 GTS card. And on Mike Davis' list, that has CUDA 1.0 capability - it turns out not to be capable of running the Beta.

It's certainly not possible to work that out from the SETI/CUDA introduction and instructions page - perhaps that could be updated sometime?

hey guys i'm a big computer guy and have a lot of friend with cuda vcards i have look at them and found that the cards bios is the cause of the card not working with seti. likely you can update that for most of them but get it for that card who makes and all specs. do at you own risk it can be done safely read and ask around for how i will not say how here.

i have an 8.500 GT and get this

that is a case where the bios update will work and has the ram on broad of at less 256 i do not know if the shard ram will work with cuda

fixed spelling

Yeah, it's

Run SETI@home on your NVIDIA GPU
Check NVIDIA's list of CUDA-enabled products.
If your GPU is listed here and has at least 256MB of RAM, it's compatible.

But Mike Davis' list is from general GPU GRID, may be compute capability of 1.0 should be supported by SETI@Home?

You're using an opti app for the MB you've been doing and are in the process of doing. As long as you use that you won't get the CUDA tasks. Once you've finished the current cache of MB, get rid of the app info file and you'll download the new files needed to do 6.05
