Detailed Description

Represents a GPU compute unit

The ComputeUnit class encapsulates the state and behavior of a GPU compute unit. It executes Warp objects, which are groups of threads that execute instructions in lockstep. The ComputeUnit manages the scheduling of warps and executes them in simple round-robin fashion.

Each warp can be in one of following pipeline stages:

-> NOT_STARTED, -> STAGE_0, -> STAGE_1, -> STAGE_2, -> STAGE_3, -> DONE.
