multiple command queue on a device

Hi forum,

Is that possible to create multiple command queues on a single device ?

I am following the opencl programming guide and it says one command queue for a single device on page 18.

On the other hand i have same running with several command queue.

I am confused.

Some explanation would be very helpful.

A short view on the class diagramm of the quick reference card tells you the answer. |queue|—<>1|context| One context many queues, one queue one context. Also [queue]—>1[device]
