Input Split Point
The Input File Size within the DNI is configurable from 1 to 32 words. The
Input Split Point defines how much data is configured as Master/Slave I/O
and how much data is configured for explicit assembly messaging.
Organization of Input Data
The following diagram describes how the Split Point parameter affects the
