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.

Abstract: An apparatus to facilitate register sharing is disclosed. The apparatus includes one or more processors to generate first machine code having a first General Purpose Register (GRF) per thread ratio, detect an occurrence of one or more spill/fill instructions in the first machine code, and generate second machine code having a second GRF per thread ratio upon a detection of one or more spill/fill instructions in the first machine code, wherein the second GRF per thread ratio is based on a disabling of a first of a plurality of hardware threads.

Abstract: Vector processing systems and methods disclosed herein generate efficient vector initialization code that leverages performance advantages of single instruction, multiple data (SIMD) instructions and immediate operands. In some embodiments, a vector processing system scans existing code for initialization syntax that specifies values which match one or more target patterns. Where the vector processing system identifies one or more of these target patterns within the specified values, the vector processing system generates enhanced vector initialization code. This enhanced vector initialization code is configured to outperform vector initialization code that sequentially loads discrete values to discrete channels within a vector register.
