WebCUFFT should respect the stream that was defined for the plan at the time the plan was passed to CUFFT via cufftExecXXX (). Subsequent changes to the plan via cufftSetStream () should have no effect on the stream used for previously issued cufftExecXXX () calls. We can verify this with a fairly simple test, using the profiler. WebJul 19, 2013 · The first step in using the CUFFT Library is to create a plan using one of the following: cufftPlan1D() / cufftPlan2D() / cufftPlan3D()- Create a simple plan for a 1D/2D/3D transform respectively. cufftPlanMany()- Creates a …
