Is there any way to convert cudaStream_t object to CUStream?
I found this hack but I don't think its safe to use.
Or, is there any way to call cudaLaunchKernel in JCuda application using cudaStream_t object in CUDA 7.5 only?

At a C level within the runtime and driver APIs,
cudaStream_tandCUStreamare the same type and can be used interchangeably in either API.At a JCUDA level, it appears that
CUstreamhas a specialization of its constructor for initializing an instance with an existingcudaStream_tinstance. The provision of this alternative constructor eliminates the need for the pointer swap you linked to in the question.
