Getting CUDA To Run

[TC]

Hey guys I'm trying to crunch with my gtx 460 while folding runs on the cpu. I read the faq for seti and cuda and it says if you have boinc 6.4.4+ it will automatically download and run the cuda client if it detects your gpu. I can't imagine that it wouldn't because for a while I was folding on this gpu, so I have the right nvidia drivers. Anyway I went to download boinc from the berkeley site and it offered me version 6.12 x64 (since I'm running 7 x64). I installed this and joined the project, but it seems to be stalled out downloading the regular intel x86 aspropulse binary. I set the prefs to always use gpu, but since this is not version 6.4.4 will it ever get the cuda client?

When you start BOINC and go to the messages tab (in advanced view or whatever) does it give you something like:

NVIDIA GPU 0: GeForce 9800 GX2 (driver version 26724, CUDA version 3020, compute capability 1.1, 498MB, 451 GFLOPS peak)

If not, then BOINC isn't seeing your card.

EDIT: It should get work for the GPU, but sometimes it takes BOINC a while to figure out how your system is set up and get the proper wus flowing.

It sounds like you haven't optimized your client yet.

Another benefit of optimizing, besides more efficient crunching and higher RAC, is that you can use the optimizer to choose what kind of work you want to do. When installing the lunatics optimizer, just select the CUDA optimizations only. Don't crunch anything on the CPU. No astropulse and don't crunch multibeam (MB) on the CPU either.

Be aware though that your folding client will slow down because CPU cycles will be diverted to support SETI CUDA. Also, your CUDA client will slow down because CPU cyles will be diverted to the folding client. Neither will give optimum performance.

What are the specs of the system you are running this on?

My first error was installing everything through remote desktop, since this machine is in a remote office. I realized it wasn't going to see the nvidia display driver when being called through an rdp session, so I installed tight vnc and ran boinc that way.

I haven't found a line like that anywhere in boinc manager - the messages tab has news stories. At any rate I installed the optimizer and told it to run cuda mb only, and that did the trick. I noticed in msi afterburnder the gpu was only running about 75-78% so I cut folding back to 11 cores so it has one to feed the gpu client, and that bumped it up in the 90% range on the gpu usage. Hopefully that's about the norm.

Thanks for the help guys :thup:
