CULA in the kernel function of CUDA

Postby thulzx » Tue Sep 24, 2013 4:51 am

Hi,
I am using CULA function to accelerate my algorithm.

Can the CULA function be used in the kernel function of CUDA?

For example, I use the function 'culaDeviceDposv' in the following kernel function

__global__ void vvdot(double *a1, double *a2, double *res)
{
...
culaDeviceDposv('U',10,10,a1,10,a2,10);
...
}

The VS compiler tells me that the culaDeviceDposv can not be used in that way.

Does it mean that the CULA function can only be used in the host?

Thank you very much.

Best regards,

CULA functions are host only.

Dear John,

Thank you for your reply.

Are the CUBLAS and CUFFT functions of CUDA used only in host?
