 4.4.2.2. PSL Procedure for AFU-Directed Programming Models

 The procedure for starting and resuming a process element in the AFU-directed programming models is implementation specific. In these models, system software adds a process element to the linked list and provides the application with a context handle. The lower 16-bits of the process handle are a pointer to the process element that contain the corresponding process state for the application. The AFU provides the lower 16-bits of the process handle (context ID) for each transaction associated with the process handle. The PSL uses the context ID to find the corresponding process element.

 In the AFU-directed programming models, the PSL does not manage any queue of processes waiting to be resumed.
