I’m using CUBLAS 3.2.
I tried to return the function call “cublasSdot” to a variable in a device memory, then I had a segmentation fault.
But return “cublasSdot” to a variable in host memory worked fine. So “cublasSdot” does NOT support return to a device memory space.
Is there any tricks to return “cublasSdot” to a device memory without copy the data from host to device?
Thanks in advance!
