parallel execution of kernels on EU's through OOQ is possible?

Hi,

I am developing an opencl kernel with Out of order execution queue. I have read this article 

https://software.intel.com/en-us/articles/opencl-out-of-order-queue-on-i... which describes the OOQ and it performance implications.

i want to understand, when two kernels are enqueued in to OOQ will these two kernels get executed simultaneously on different EU's?.  i am not able to conclude that from the article. What i understand is that even in the OOQ the kernels are executed serially not simulataneously on the EU's.

please clarify this confusion.

Best Regards,

Rajesh
