Function Documentation

DeclareDebugSlot

(

network_switch

)

The network_switch class A class encapsulating a network switch that packets must traverse on the network. The network switch performs both routing computations and congestion modeling.

rter

Returns

The router used for performing routing computations

queue_length Compute the number of packets waiting on the switch. The queue length is a multiple of the ``system'' packet size, which can be different from the packet size used by SST/macro congestion models. For example, the packet size of the system beings simulated might be 100B, but SST/macro might be doing congestion computations on units of 1024B.

Parameters

port	The port to check the queue length of

Returns

The queue length as an integer number of packets waiting

Parameters

addr	The destination node addr to eject to

Returns

The ejection port the node is connected on

Parameters

addr	The source node addr to ack to

Returns

The injection port the node is connected on

The total hop latency to transit from input of one switch to the next (with zero congestion)

lookahead For parallel simulations, returns the maximum PDES lookahead possible between two network switches. This is usually (but not always) the sames as the hop latency

Returns

The PDES lookahead

The bandwidth observed hopping from switch to switch (with zero congestion)

connect

Parameters

src_outport	The port that packets will exit on the source
dst_inport	The port that packets will enter on the destination
ty	The type of connection (usually just output or input) An output connection is a data link that carries payload from src to dst. An input connection is a control link that usually just carries credit/arbitration info from dst to src.
mod	The dst (if output link) or src (if input link)
cfg	An special configure options for the link
