Can scalar and vector operations run in parallel in GCN?

Well the question already tells most of what I would like to know. Since vector and scalar ALU are different pieces of hardware I wondered if the two alus can be active in parallel when the instructions running have no data dependencies.
Would like to know if this would work at all or maybe only conditional (e.g. when they are both max 32 bit encoded operations) or well - if the two can not run in parallel at all Sadly was not able to find any information about in CU parallelism - different to old TeraScale architecture where some instruction sorting may have helped performance.

 

Thanks
