Detailed Description

This structure provides a generic datatype descriptor that is used for definition of application defined datatypes.

Typically, the descriptor is used for an integration with datatype engines implemented within MPI and SHMEM implementations.

Note: In case of partial receive, any amount of received data is acceptable which matches buffer size.

The documentation for this struct was generated from the following file:
