Detailed Description

Static-Spawning Interface.

This is a part of the spawning library (https://github.com/riken-rccs/mpispawner). See also the source code of the KMR map-reduce library for the use of spawning (https://github.com/riken-rccs/kmr). It is the worker-side of the master-worker protocol, and the master-side is in "kmrwfmap.c" in KMR. Note that this code is also included in KMR to implement a dummy spawning for testing.

Definition in file kmrspawn.c.
