I want to upgrade my preconditioned conjugate gradient solver from CUDA 8.0 to CUDA 11.0.
But the functions (eg. csrsv2, csric02) require a variable “cusparseSolvePolicy_t” which is not defined in CUDA 8.0.
The documentation only says it is used to generate the level information, but I don’t quite understand what it means.
Does anyone know what does that mean?
Can you tell me what’s the difference between NO_LEVEL and USE_LEVEL ?
