From the Altera SDK for OpenCL Optimization Guide:

"If you update one element of a vector type, update all the elements of the vector, as

shown in Example 17. 


__kernel void update (__global const float4 * restrict in,
                      __global const float4 * restrict out)
{
    size_t gid = get_global_id(0);
    out.x = process(in.x);
    out.y = process(in.y);
    out.z = process(in.z);
    out.w = 0; //Update w even if that variable is not required.
}
