KINDMPIADDRESSKIND

KINDMPIADDRESSKIND is a data type used in the Message Passing Interface (MPI) standard, a widely used standard for communication between processes in a parallel computing environment. This data type is part of the MPI-3.0 specification and is used to describe the kind of address used in MPI operations.

In MPI, processes communicate by sending and receiving messages. These messages are identified by their addresses, which can be of different kinds depending on the underlying system and the type of communication. The KINDMPIADDRESSKIND data type is used to specify the kind of address used in MPI operations, such as MPI_Alloc_mem, MPI_Get_address, and MPI_Win_create.

The value of KINDMPIADDRESSKIND is an integer that represents the kind of address used. The possible values are system-dependent and are defined by the MPI implementation. However, the MPI standard specifies that the value of KINDMPIADDRESSKIND should be one of the following: MPI_ADDRESS_KIND, MPI_BASIC, MPI_DATATYPE_NULL, or MPI_WIN_BASE.

The KINDMPIADDRESSKIND data type is used to ensure portability of MPI programs across different systems and MPI implementations. By specifying the kind of address used, MPI programs can be written in a way that is independent of the underlying system and MPI implementation, making them more portable and easier to maintain.

In summary, KINDMPIADDRESSKIND is a data type used in the MPI standard to specify the kind of address used in MPI operations. It is used to ensure portability of MPI programs across different systems and MPI implementations. The value of KINDMPIADDRESSKIND is an integer that represents the kind of address used and is system-dependent.
