any CUDA developers out there?

Hello All,

I am working on a CUDA program to accelerate simulations for
radiation therapy.  I am also an Arch Linux user.  Things
generally work quite well thanks to the work of the nvidia and
cuda package maintainers.  However, there are often a few bumps
in the road.  Right now I am having some form of permissions
problem where I have to run my CUDA programs as root if I want
them to see my second GPU.

Are there any other CUDA developers out there?  Is there any interest in
forming some kind of support group or mailing list?

Cheers!

In case you don't get feedback here, you might try the existing CUDA Developer Forum.

I am learning programming now.  Cuda is very interesting indeed.  There are a few issues with the root cuda bug, Google shows a few.  I haven't tried the cuda toolkit yet. 

I hope you find the solution.

Re: any CUDA developers out there?

do you get this when you try to run the supplied example programs ?
when i installed it, the whole package installed to /opt and owner was root only.
i found i could not compile the examples. i copied the whole cuda to my home, then changed ownership. i could then run the examples (just tried clock and vector add).
which examples gives you problems ?

I am also a CUDA developer and I use Arch (obviously!). If you have questions concerning CUDA, you can try StackOverflow or the official CUDA forums. As for your bug, more information is required if you want an answer. CUDA does not require root permissions, but the programs that you are compiling/launching may be owned by root (e.g. the samples in /opt/cuda as arobson73 said).

It would be helpful if you explain the problem in more detail, not just "some form of permissions problem". Your problem might not even be CUDA specific.

Re: any CUDA developers out there?

I used to fiddle around with CUDA when using the jacobi iteration method to solve some large linear equation systems. was kinda cool but due to the lack of application back then I lost interest soon. But I also did everything on Arch. Everything went just fine back then smile
