Does the OpenCL2.0 SVM support allocate memory for images?
We can test the SVM performance like:
d_a=(float*)clSVMAlloc(context,(CL_MEM_READ_WRITE|CL_MEM_SVM_FINE_GRAIN_BUFFER|CL_MEM_SVM_ATOMICS),size,0);
d_b=(float*)clSVMAlloc(context,(CL_MEM_READ_WRITE|CL_MEM_SVM_FINE_GRAIN_BUFFER|CL_MEM_SVM_ATOMICS),size,0);
d_c=(float*)clSVMAlloc(context,(CL_MEM_READ_WRITE|CL_MEM_SVM_FINE_GRAIN_BUFFER|CL_MEM_SVM_ATOMICS),size,0);
for(int i=0;i<size;i++)
{
d_a[i]=Initial_value;
d_b[i]=Initial_value;
}
clSetKernelArgSVMPointer(kernel, 0, d_a);
clSetKernelArgSVMPointer(kernel, 0, d_b);
clSetKernelArgSVMPointer(kernel, 0, d_c);
The SVM performance has been verified good in the example of calculation of a vector,but the clSVMAlloc() cannot allocate memory for images,
how should we do to utilize the SVM for image processing?
Thank you!
