Demos failing with CUDA 5 about scikit-cuda HOT 9 CLOSED

I haven't had occasion to test scikits.cuda with CUDA 5 yet, so I can't comment at this point. Try downgrading to CUDA 4. I'm leaving this issue open until I have a chance to investigate.

from scikit-cuda.

Will do tonight, and let you know.

Have you tested it against 4.0, or some newer 4.x version?

I downgraded to 4.2, and I still am receiving the same errors. Running dot_demo.py:

Are you using the latest revision from Github? The tests seem to run without any issues when I tried running them against the latest revision on a system running CUDA 4.2.9 and CULA R15.

I'll double-check that I'm running with exactly the same versions as you list.
Also, I'm running Ubuntu 12.04, with a GeForce GTX 660.

from scikit-cuda.

I ran the tests on Ubuntu 12.10 with a GeForce GTX 460 using the stock CUDA 4.2 packages available for that version of the distro.

from scikit-cuda.

Tested latest revision in Github against CUDA 5.0.35 on Ubuntu without any problems.
