matlab parallel computing/GPU error msg
조회 수: 6(최근 30일)
kp = parallel.gpu.CUDAKernel('derivative.ptx','derivative.cu','derivative');
my error message:
"??? Undefined variable "parallel" or class "parallel.gpu.CUDAKernel"."
I know that my code is not completely right, but I expect it gets something else, at least not this error message, which I do not know how to interpret. Does that mean I do not have a nVidia GPU card on my computer? Or does that mean my Matlab is too old (R2009) to support parallel computing? Surprisingly, when I googled this error message, not many results showed up.
I ran the same line on another machine, the error message was:
"Error using handleKernelArgs (line 48) The first input to parallel.gpu.CUDAKernel must be a file that contains PTX code or a string that is PTX code."
So can I still use parallel computing on my computer? If so, what should I do?
Any suggestion is appreciated. Thanks a lot.

I think it means you do not have the Parallel Computing Toolbox. Try
at the command line.

Right: PCT not installed or not licensed.
PCT is an optional extra-cost toolbox.
Further note: GPU use requires an NVidia card with CUDA 1.3 or later. There are a lot of NVidia cards that support only CUDA 1.2, so before spending money on the PCT, check the CUDA version supported by your card http://developer.nvidia.com/cuda-gpus
