The parameter determines the minimum number of MPI buffers (granularity of the Memory Pipes) read by the network so that a rolled out context can be rolled back into a work process (by the ICM).

To make sure that no work processes are occupied unnecessarily if the network connection is slow, you can use this parameter to ensure that the context only occupies one work process if data are also available.
