Detailed Description

DispatchGroup groups a series of compute pipeline dispatches that need to execute sequentially (i.e. with a barrier). Dispatches are stored in the order that they will be encoded in the eventual command buffer.

A DispatchGroup can be constructed from a series of ComputeSteps using a Builder. The Builder verifies that the data flow specification between successive ComputeSteps are compatible. The resources required by a ComputeStep (such as Buffers and TextureProxies) are created by the Builder as they get added.

Once a DispatchGroup is finalized, it is immutable. It contains the complete ResourceBinding list for each dispatch. A list of finalized DispatchGroups can be submitted to the command buffer in a ComputeTask.
