Detailed Description

Maps related utilities.

This utilities are used to set up a mapping between MPI programs (ie. which instrumented program communicates with which analyser program).

As indicated in VMPI_Map_mode enum, three mappings are implemented (with 6 MPI programs) :

Warning

The fixed mapping is only possible when there are the same number of instrumented and analyser programs.

Enumeration Type Documentation

enum VMPI_Map_mode

Defines mapping method.

Enumerator
VMPI_MAP_FIXED	Associates each process to one process.
VMPI_MAP_RANDOM	Randomly associates processes.
VMPI_MAP_ROUND_ROBIN	Map processes in a round robin fashion.

Function Documentation

static void VMPI_Map_clear ( VMPI_Map *  map )

inlinestatic

Clears a map.

should be called before any call to VMPI_Map_partition

Parameters

map	The map to be cleared

Definition at line 300 of file VMPI.h.

Here is the caller graph for this function:

int VMPI_Map_partitions	(	int	target_partition,
		VMPI_Map_mode	mode,
		VMPI_Map *	map
	)

Map to another partition (can be additive)

Parameters

target_partition	ID of the target partition
mode	mapping mode as stated in VMPI_Map_mode
map	output map

Returns

a VMPI_Return_Status

This functions performs a "real" collective call. It means that not only one program will do that, but every partitions (ie. every programs given to mpirun)
