ExecutionContext

This week we made a large structural change to the way Graphs are built and CompiledFunctions are run. The execute()function (and associated HostManager/DeviceManager interfaces) now take an ExecutionContext object which replaces the old Context object. The ExecutionContext is a container for three objects required for execution in the Glow runtime:

  • PlaceholderBindings (renamed from Context), which map input and output Placeholders to Tensors.
  • DeviceBindings, which contain Device specific information pertaining to a specific run. This allows moving run specific state out of the CompiledFunction, allowing the same CompiledFunction to be executed on multiple devices concurrently.
  • TraceEvents, which store any profiling events generated during the run.
