void sstmac::hw::fake_topology::compute_switch_coords	(	switch_id	swid,
		coordinates &	coords
	)		const

inlineprotectedvirtual

Compute coordinates (e.g.

X,Y,Z for 3D torus)

Parameters

swid	The unique index defining a switch location
coords	[inout] The unique coordinates of the switch

Implements sstmac::hw::structured_topology.

Definition at line 124 of file fake_topology.h.

void sstmac::hw::fake_topology::connect_objects ( internal_connectable_map & objects )

inlinevirtual

Given a set of connectables, connect them appropriately.

Parameters

objects	The set of objects to connect
cloner	If in parallel mode, not all objects may exist. The factory creates missing objects.

Exceptions

value_error If invalid switchid is passed to cloner

int sstmac::hw::fake_topology::minimal_distance	(	const coordinates &	src_coords,
		const coordinates &	dest_coords
	)		const

inlinevirtual

The function accepts either source or node coordinates.

This gives the minimal distance counting the number of hops between switches. If node coordinates are given, the last coordinate is just ignored.

Parameters

src_coords.	The source coordinates. This can be either switch or node coordinates.
dest_coords.	The destination coordinates. This can be either switch or node coordinates.

Returns: The number of hops to final destination

void sstmac::hw::fake_topology::minimal_route_to_coords	(	const coordinates &	src_coords,

		structured_routable::path &	path
	)		const

inlinevirtual

Workhorse function for implementing minimal_route_to_switch and #minimal_route_to_node.

Given source/dest coordinates, find the minimal path.

Parameters

current_sw_addr	The addr of the current switch
dest_sw_addr	The addr of the destination switch
path	[inout] A complete path descriptor to the destination switch

Implements sstmac::hw::structured_topology.

Definition at line 55 of file fake_topology.h.

int sstmac::hw::fake_topology::ndimensions ( ) const

inlinevirtual

The number of distinct 'dimensions' in the topology.

This can correspond directly to standard X,Y,Z dimensions or the the number of levels in a fat tree. The keyword topology_redundant vector should have this many entries.

int sstmac::hw::fake_topology::num_leaf_switches ( ) const

inlinevirtual

Structured topologies can be direct (torus) or indirect (fat tree).

We therefore need to distinguish the total number of switches and the number of leaf switches - i.e. those directly connected to nodes. For direct topologies, num_switches and num_leaf_switches are the same. For indirect, num_leaf_switches < num_switches.

Returns: The number of leaf switches directly connected to compute nodes

Parameters

dim	The dimension you want to move in. You might need to traverse other dimensions FIRST before you make progress on this dimension.
src	The coordinates of the source switch
dst	The coordinates of the dest switch
path	[inout] The path configuration for making progress on dim
