openacc fortran & cufft problem

Hello all. I’m a postgraduate and working on accelerating a Fortran 90 program on GPU with openacc recently. The issue I face now is that how to get cufft library accessible in loops from device code . I’ve already known that it’s working well on host. Does anyone have ideas or successful examples about that?


cufft only has interfaces for calling from the host. Not from device code.
