Calling Sequence

Prior to invocation of an HPF_SERIAL procedure from global HPF, the behavior of the program will be as if the following actions take place:

1. The processors are synchronized. All actions that logically precede the call are completed.

2. All actual arguments are remapped to the processor that will actually execute the HPF_SERIAL procedure. The argument will appear to the HPF_SERIAL procedure as a sequential argument.

The behavior of the HPF_SERIAL procedure will be as if it was executed on only one processor. After the instance of the HPF_SERIAL procedure invoked from global HPF has completed, the behavior will be as if the following happen:

1. All processors are synchronized after the call.

2. The original mappings of actual arguments are restored.
