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.

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:
