Hi, for my research I'm trying to implement a custom routing algorithm in
gem5/garnet.
Someone from the mailing list recommended that I should go for the Mexh_XY
routing algorithm to understand how it's working.
The mesh topology i'm using contains only 4 cpus and 4 dirs and number of
mesh rows is 2, and the routing-algorithm option is set to 1
here is the full simulation command i'm using
*sudo build/NULL/gem5.debug --debug-flags=RubyNetwork
configs/example/garnet_synth_traffic.py --num-cpus=4 --num-dirs=4
--mesh-rows=2 --network=garnet --routing-algorithm=1 --topology=Mesh_XY
--synthetic=uniform_random --injectionrate=0.1*
In the file mem/ruby/garnet/RoutingUnit.cc --> the function outportComputeXY
int RoutingUnit::outportComputeXY(RouteInfo route, int inport,
PortDirection inport_dirn)
I'm trying to get some output during the simulation to understand the
routing table at each router and how the lookup table works.
The following is my code. I'm using a file to get the data during the
simulation
So, the file will print the following:
[RouterId] [DestinationRouter] [hops_x] [hops_y] [InportDirn] -->
[outport_dirn] [router_x, router_y] [des_x, dest_y].
and output the lookup table attached to the router.
std::ofstream myfile;
// open the file in appending mode
myfile.open ("routing_output.txt", std::ios_base::app);
myfile << m_router->get_id() << "\t" << route.dest_router << " |
hops_x: " << x_hops << " | hops_y: " << y_hops << "\t";
myfile << inport_dirn << " --> " << outport_dirn << "\t" <<
m_outports_dirn2idx[outport_dirn] << "\t" << my_x << ", " << my_y;
myfile << " --> "<< dest_x << ", " << dest_y << std::endl;
// iterate over the outports table map and write the data to the file.
std::map<std::__cxx11::basic_string<char>, int>::iterator it;
for(it = m_outports_dirn2idx.begin(); it != m_outports_dirn2idx.end();
it++)
{
myfile << it->first << "\t" << it->second << std::endl;
}
myfile.close();
Here are some samples of my output file and also the full txt file is
attached.

I don't really know how the packets are routed and also how the lookup
table works. also i can't imagine the connections between the nodes i tried
to draw a flow chart for each router
but some of the output data doesn't match the drawing -- like a packet from
router #2 will go east !!

Can anyone explain to me? or if there is any documentation I can check to
understand this.
