Abstract

Embodiments provide support for divergent control flow in heterogeneous compute operations on a fused execution unit. On embodiment provides for a processing apparatus comprising a fused execution unit including multiple graphics execution units having a common instruction pointer; logic to serialize divergent function calls by the fused execution unit, the logic configured to compare a call target of execution channels within the fused execution unit and create multiple groups of channels, each group of channels associated with a single call target; and wherein the fused execution unit is to execute a first group of channels via a first execution unit and a second group of channels via a second execution unit.
