Is anyone able to run gpu-based conv2 on a GTX 1080 or other pascal hardware?

I repeatedly get unspecified CUDA launch errors, despite the function calculating correctly on older Maxwell hardware using the same datasets. Can anyone else reproduce this?
Thanks, Nick

Well, there are no obvious problem there, except that KernelExecutionTimeout is 1. But that is also true on my machine and I have no issues.
I'm going to get someone with Windows and a GTX 1080 to test your code, and then I may have to move you over to tech support. Meanwhile you should try some different legacy drivers listed at http://www.nvidia.com/Download/Find.aspx?lang=en-us.

Your issue reproduces on a GTX 1080 on Windows. Thanks for reporting. It will take a little while to investigate this.

No problem, like I said above the ifft(fft*fft) approach works and the performance hit isn't that severe to my application. I'm mostly glad I can stop pulling my hair out trying to figure out what I've misconfigured. Thanks for being so responsive.
