I'm not sure what's wrong. I haven't used this function much but my little test cases seem fine. Instead of me trying to figure out how to recreate the error, can you send me your tests?


A tarball is whizzing its way to you!

Thanks for the help,
Matt

Hi Matt,

For the seg fault, you're suppose to be able to pass in a function pointer and the CUDA runtime makes the association, but I don't think we're do this correctly. I add TPR#17878 and sent it to our engineers.

For the 'invalid device function' error, this is because the function name is actually 'soradmod_soradcuf', not 'soradcuf' since it's in a module. It seems to be happy if I use:

istat = cudaFuncSetCacheConfig('soradmod_soradcuf',cudaFuncCachePreferL1)

Can you give this a try and see if it works for you?

- Mat
