Message Routing
When the Manager/Worker paradigm is initialized with a routing option other than SPDI_NO_ROUTING, in order to ensure that the messages are routed properly the following calls must be made prior to sending a message depending on the routing strategy:
SPDI_STATUS_CODE_ENUM SPDI_RouteByProcessRank(int rank);
SPDI_STATUS_CODE_ENUM SPDI_RouteByXmtlName
SPDI_STATUS_CODE_ENUM SPDI_RouteByXmtlNameFromObject
