I tried to use the GPU LU solver but found that it doesn’t exist. The documentation says it supports both GPU and Host routines (it has the ‘[Host]’ after the function like the other functions do). I checked the cusolverSp.h header and found the cusolverSpcsrlsvluHost routine, but it’s labeled as the GPU routine in the comments section. The GPU-style function reference does not exist. Thinking perhaps it was a bug in the header, I added the cusolverSpDcsrlsvlu routine but it doesn’t exist in the library. Which documentation is correct? Is my install corrupted, or is only the Host supported? ---

Only the Host path is available/supported in the current (CUDA 7) version of this library for this particular function. ---

Ok. Thanks for the reply txbob.
