	I am in a kind of strange situation where I really need to run CUDA units only and nothing on my CPU's. Is it possible to only run CUDA? Motherboard : Intel DG965RY Processor : Intel Core 2 2.13 Memory : 4gb PC8500 OS : WIndows 7 Video : Nvidia 8800GT 512 ____________

	I am in a kind of strange situation where I really need to run CUDA units only and nothing on my CPU's. Is it possible to only run CUDA? Yes. If you do everything to run CUDA - BOINC v6.4.5, updated CUDA drivers (from Windows Update IIRC for Windows 7), BOINC not installed as a service, MB and GPU processing enabled in preferences - then CUDA should run. Then, provided you don't join any other project (or set 'No New Tasks' for any other projects you've already joined), and dis-allow Astropulse in your profile preferences, the CPU won't be sent any BOINC work to do. This is one case where the BOINC 'bug' of not sending CPU and GPU versions of the same application actually works as a 'feature' for the scenario you describe.

Downgrading to v6.4.5 should restore the "bug/feature" as described.

Raistmer has done a lot of work to enable both cpu AND gpu processing, so in your situation you want to avoid those. [edit]You have to do extra work to get his apps, so if you don't have an app_info.xml file installed you should be just fine.[/edit]

	I too have situations where I would like my machine to only run CUDA and not CPU. Any chance in future versions they'll had a 'preference' checkbox where you could disable CPU work? ____________

	No, it won't. It will just not allow any project to use the CPUs. ____________ Jord - BOINC FAQ Service - BOINC User Wiki Real is just a matter of perception.

	Does anyone know if this will affect gaming performances, or will CUDA switch automatically using the CPU? The reason why I ask here, is because, I had a thread that asked the same question, but was summarily deleted, for reasons beyond me ____________ the truth is out there

The reason why I ask here, is because, I had a thread that asked the same question, but was summarily deleted, for reasons beyond me If your thread was 'hidden', then you should have received a message to say why. Take a look at your account for a PM? My answer in that thread was a "maybe". Best is to try it and see. You can always suspend Boinc whilst you're gaming and reenable when done. Or select the "don't use whilst busy" or whatever. Try experimenting! The Boinc CPU clients certainly shouldn't interfere with CPU responsiveness. However it is very early days for the CUDA stuff and CUDA is very sensitive to the amount of VRAM and to what you are doing with the graphics.

	The posts haven't been 'hidden', they've been moved to the CUDA 'Question and Answer area: CUDA question. Some new answers have been added. If the system is the same as when I was briefly a mod, the system doesn't automatically send a PM when a moderator intervenes. The thread originator (lynxtra) should get an email, but other contributors to the thread didn't even get that in my time. Any PM would be at the individual discretion of the mod concerned - they would have to send it manually.

I've been trying to keep all CUDA related Q&A's over in the Q&A section of the message board... which reminds me that I should move this one too. ____________

Had to bump this thread since there's a restriction on me creating a new one (becuase I have no credits.) I'm running a dual processor SMP set up on Ubuntu 8.04 with Boinc 6.4.5 and also have a CUDA enabled GPU. I've followed the instructions to get set up. I unchecked Astropulse and my preferences are set to GPU processing. What is the 'MB'? I should mention that when I downloaded the SETI work unit, I had Nvidia driver 177.** installed, but now I have 180.29. Will that make the difference? As it is right now, I have one CPU working on one unit, the 2nd working on SETI and my GPU isn't being used by SETI. I figured I'd have my 2 CPUs working on other projects and my GPU on SETI CUDA only. That's my goal anwyay. ____________

There are two types. One that is processed on your cpu is version 6.03. CUDA variety is 6.08. ____________

	Thanks Byron. Unfortunately I'm also on the 32-bit platform so that means no projects currently have CUDA supported for my hardware. No biggie. I'll re-attach if/when I can use my GPU. ____________

	AFAIK, SETI CUDA stock version is Windows only ATM. Not quite. There is a test version available from Crunch3r.

	Ok. Cuda is nice, But.... I`ve got 3 PC. 2 of them have a Intel C2D E8400 3.00 Ghz @ 3.60 Ghz 1 of them have a Intel C2D E6400 2.13 Ghz @ 3.00 Ghz #1. Pc got 8800GT, #2. 8600GT. #3 9800GTX+ (All of them got Nvidia GPU) There is lot of computing power in those cards. But when suspended..... All of them are running full time, 24/7 100%. And all of them can use CUDA, but it slows down the computer if we are playing FPS, games. For me it is easy too suspend CUDA work, but for my kids, it`s not soo easy. And here we goo :-) Why can`t they make a "button", to press in the BOINC system tray, soo we can suspend CUDA work ?. It should bee easy to program a "short cut", too suspend CUDA whenever, and "hit" the same "button" too start CUDA work again ? Soo what doo they say about it ?, since the PC are running all the time, and just used for gaming a short time every day ?. It would be easy for all of us if they could make it (short cut) to disable CUDA work. Hope someone can tell me / us why not, or even better program it. :-) Thanks. ____________

	Go here and check out the settings for <exclusive_app> BOINC will suspend computing whenever the executable is running (e.g., a game). Multiple applications can be specified.
