<p class="MsoNormal"><span lang="EN-US">I have a kernel with float3 argument. In C++ code I use cl_float3 (which is actually cl_float4). When I call clSetKernelArg with 3rd argument sizeof(cl_float3) it gives me an error CL_INVALID_ARG_SIZE. If i use my own
structure with just 3 floats - it works. With NVIDIA it works with cl_float3 just fine. Is it a bug?<o:p></o:p></span></p>
