CUDA-x86 SDK

Hi, all:

I have PGI Fortran/C/C++ Workstation (12.3 version) on the linux and I can find my NVidia GTX 590 Ti through executing devicequery in the directory “/opt/pgi/linux86-64/2012/cuda/CUDA-Fortran-SDK”.
However, I can only get the following message while executing devicequery in the directory “/opt/pgi/linux86-64/2012/cuda/CUDA-x86-SDK/bin/release”.

Why…? Thank you in advance.

./deviceQuery Starting…

CUDA Device Query (Runtime API) version (CUDART static linking)

There is 1 device supporting CUDA

Device 0: “DEVICE EMULATION MODE”
CUDA Driver Version: 99.99
CUDA Runtime Version: 99.99
CUDA Capability Major revision number: 9998

Hi Feng,

CUDA-x86 emulates an NVIDIA device on a host CPU but does not target the device itself. Hence, the output from the device query is correct. To target your NVIDIA device using CUDA C, please use NVIDIA’s nvcc compiler.

Hope this helps,
Mat

Hi Mat,

I got it. Thank you for reply.
