Does Cuda7.5 support Pascal Titan X? Thanks
CUDA 7.5 does not have native support for the Pascal architecture (GTX 1060, GTX 1070, GTX 1080, Pascal Titan X). You could theoretically use the CUDA 7.5 tool chain to compile your code into a binary with embedded PTX, and let the appropriate driver for the Pascal Titan X JIT compile that into machine code.
In practical terms, the preferable approach would be to install CUDA 8.0 (currently available as a release candidate) if you plan to deploy the Pascal Titan X at this point.
