This is the kernel I am trying to compile.
//KERNEL_SIMPLE
__kernel void Convolve(const __global float * pInput,
__constant float * pFilter,
__global float * pOutput,
const int nInWidth,
const int nFilterWidth)
{
const int nWidth = get_global_size(0);
const int xOut = get_global_id(0);
const int yOut = get_global_id(1);
const int xInTopLeft = xOut;
const int yInTopLeft = yOut;
float sum = 0;
for (int r = 0; r < nFilterWidth; r++)
{
const int idxFtmp = r * nFilterWidth;
const int yIn = yInTopLeft + r;
const int idxIntmp = yIn * nInWidth + xInTopLeft;
for (int c = 0; c < nFilterWidth; c++)
{
const int idxF = idxFtmp + c;
const int idxIn = idxIntmp + c;
sum += pFilter[idxF]*pInput[idxIn];
}
}
const int idxOut = yOut * nWidth + xOut;
pOutput[idxOut] = sum;
}
//KERNEL_SIMPLE

Hi Dave,
Can you please let us know your inputs to Kernel Builder (what you fill your buffers with, and the global/local group sizes you use)?
Also, I assume you are using the 2013 SDK (or 2012) - can you please let us know your exact version?
Thanks,
Oren
