5.8.4 Enqueuing kernel execution

When you have identified the dimensions necessary to represent your data, the necessary work-items for each dimension, and an appropriate work-group size, enqueue the kernel for execution using clEnqueueNDRangeKernel().

For example:

size_t globalWorkSize[1] = { ARRAY_SIZE };
size_t localWorkSize[1] = { 4 };

//   Queue the kernel up for execution across the array

errNum = clEnqueueNDRangeKernel(commandQueue, kernel, 1, NULL, globalWorkSize, localWorkSize, 0, NULL, NULL);

if (errNum != CL_SUCCESS)
       printf("Error queuing kernel for execution.\n");
       return 1;
