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.

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,
