question about radeon pro duo ( Fiji version )

Greetings all , i would  like to buy a radeon pro duo considering also the fact that a local distributor has a piece in stock giving it away at a very low price locally . Prior to purchase i would like to know if it would be possible to split the loads among the two chips of the cards ... For instance i have some software that could use one "FIJI chip" to leave some open cl calculation and use the other to game  without affecting the performance of the other core ? Will the driver will allow  this ?
