Noticed today that you can now run Boinc on NVIDIA Gpu's like you've been able to do with Folding At Home. This would be another great way for people to contribute to our SETI team. Details in the link.

A version of SETI@home that runs on NVIDIA graphics boards using their CUDA computing engine has been released. The CUDA version runs up to 10X faster than the CPU version. NVIDIA has put out a press release about the SETI@home CUDA client and about GPU Grid. See directions for getting started.



Quote:
SETI@Home
Researchers in the scientific field of SETI received a massive increase in computing power today, when NVIDIA and BOINC released an optimized client that will allow SETI@home to be accelerated on GeForce GPUs. SETI@home, the largest BOINC project with nearly 200,000 active users, searches for extra terrestrial intelligence by using radio telescopes to listen for narrow-bandwidth radio signals from space. The performance of a GeForce GTX 280 GPU running SETI@ is nearly 2 times faster than the fastest consumer multicore CPU (3.2GHz Intel Core i7 965) and almost 10 times faster than an average dual core consumer CPU (2.66 GHz AMD Phenom 9950)ii

Just shows how powerful todays GPUs are - for the subset of tasks they can do.

I've been trying to get it running on the GPU in my laptop. No luck. Tried both Dell modified video driver that it came installed with as well as the "proper" one from Nvidia.

Page load error here atm :(

However a cached version thanks to google allows me to get to the downloads that still work.

Link.

Finally got it up and running, well sort of. Having major stability issues with it and my laptop is damn near unusable now when running SETI. Will look into another client but I may go back to just using my CPU for SETI.

What type of stability issues? It's okay here.

Not sure if I know enough about video cards to properly explain but I will try. After thirty minutes or so I started to get what I would best describe as static. Kinda like only 1 in 10 pixels would render at a time. It wasn't the same pixels, it was all over the place. Attempting to fix the issue was impossible so I had to do a hard shut down and reboot. I've been able to run it since then without the problem reoccurring. Not a stability issue but if I am running CUDA and I try to watch a video at the same time I can not render it at full frame at anything more then about 10fps. I'm off the next few days so I plan on tweaking some things and seeing if I can get this to work right.

Well your issues make sense to me. The static could be as simple as heat build up. You can try to downclock your videocard and bit and see if you can still run SETI on it while maintaining a proper display. The video running slow would likely be because your card can't render as quickly since it is currently processing other processes or it could be that the heat is causing it to re-calculate due to errors. Pretty common when you OC processors and the heat gets to be too much.

heat and laptops dont go well together , might wanna cancel it, a desktop with a new nvidia card would be faster , most likely an old Nvidia gfx chipset and a dual cpu prolly be rather close to eachother in performance.

Not sure if you read the topic where the onboard Nvidia gfx chips melt/break down due to overheating easily ...

These cuda optimised units take about 10 to 30 minutes on my dual gainward 9600 GT SLI setup.

StANTo I can't believe it's taking that long for those work units to complete. I'm not running the CUDA client often but when I do I am completing work units in just a few minutes. Doing so using a 256mb 8600m GT.

I have SLI enabled, not sure if that makes a difference.

i got some units 8 mb big and they like take over 100 hours to complete on my 3.6 ghz X3 720 BE :) .

Now lets hope i get 1 zillion billion points for completing them ;)
