FNC_AMPInfo returns a pointer to an AMP_Info_t structure.
The AMP_Info_t structure is defined as:
typedef struct { unsigned short NodeId; unsigned short AMPId; unsigned short LowestAMPOnNode; } AMP_Info_t;
Member … | Specifies … |
---|---|
NodeId | the unique number of the node. |
AMPId | the unique number of the AMP. |
LowestAMPOnNode |
whether the current AMP is the lowest AMP on the same node as the invoking AMP. If this function is invoked from a table operator that is associated with a map, then LowestAMPOnNode specifies whether the current AMP is the lowest AMP on the same node within the specified map. A table function or operator that allows only the lowest AMP vproc to participate can use this field. The value of LowestAMPOnNode is as follows:
