Hi David,

This is actually a warning message means a NULL local_size was passed into the enqueue and we could not find the best value in runtime. If you want to have the best performance, you can try different local_size and keep the best one instead of passing NULL local size.

If there is any problem with the dnetc, could you provide the full log please. I could not open the link you provide.

Thanks
Xiuli
