Abstract

Embodiments include an apparatus, a computer readable medium and a method for distributing tessellations within an accelerated processing device (APD) including at least two compute units. Embodiments include processing a plurality of patches in a first compute unit using a hull shader to generate hull shader output data. Once generated, hull shader output data is stored to an off-chip memory when tessellation factors associated with the shader program are greater than a configured threshold. Once stored in the off-chip memory, at least a portion of the hull shader output data is dynamically processed using a second compute unit.
