If I have code:
::brook::Stream<float>* divG;
which has some data and I want to make temp variable that has the same data. If I write
::brook::Stream<float> *temp=new ::brook::Stream<float>(*divG);
which I thought is a copy constructor, then I cant use this temp variable in a call like this:
calculate_and_add_divergence_gpu_ati(cols,rows,*Gx,*Gy,*temp,*divG)
where divG is output stream. The runtime reports the error: "Input stream is the same as the output stream."
I get the same error even after the code like this:
temp->assign(divG);
or
*temp=*divG;
If I could just get the dimension of divG I could make a temp variable like
::brook::Stream<float> *temp=new ::brook::Stream<float>(1,&dimension); And then use assign method.
Here is the kernel which I am calling:
kernel void calculate_and_add_divergence_gpu_ati(int cols,int rows,float Gx[],float Gy[],float temp<>, out float divG<>
{
float divGx, divGy;
int idx=instance().x;
int ky = idx % cols;
int kx=idx-ky*cols;
if(kx == 0)
divGx = Gx[idx];
else
divGx = Gx[idx] - Gx[idx-1];
if(ky == 0)
divGy = Gy[idx];
else
divGy = Gy[idx] - Gy[idx - cols];
divG = temp + divGx + divGy;
}
So the simple method getDimensions of class Stream would be really nice.
Thank you for your support.
multi mon and crossfire combined
get it fixed or else
