Detailed Description

Dummy communication implementation for testing purposes.

Function Documentation

◆ test_initialize()

int test_initialize ( )

Perform initialization of a dummy communicator for testing purposes.

◆ test_recv()

int test_recv	(	void *	buf,
		int	count,
		MDI_Datatype	datatype,
		MDI_Comm	comm,
		int	msg_flag
	)

Dummy function to handle receiving data through an MDI connection, for testing purposes.

Parameters

[in]	buf	Pointer to the buffer where the received data will be stored.
[in]	count	Number of values (integers, double precision floats, characters, etc.) to be received.
[in]	datatype	MDI handle (MDI_INT, MDI_DOUBLE, MDI_CHAR, etc.) corresponding to the type of data to be received.
[in]	comm	MDI communicator associated with the connection to the sending code.
[in]	msg_flag	Type of role this data has within a message. 0: Not part of a message. 1: The header of a message. 2: The body (data) of a message.

◆ test_send()

int test_send	(	const void *	buf,
		int	count,
		MDI_Datatype	datatype,
		MDI_Comm	comm,
		int	msg_flag
	)

Dummy function to handle sending data through an MDI connection, for testing purposes.
