Hi Tushar,

Can I ask you a problem of router in garnet network? I use fixed pipeline,
garnet network.

I want to capture the request that entering each router, then in
network/Garnet/Fixed-pipeline/Router_d.cc, I find that "route_req" method.
In this method, I can print out which router is using and which input unit
is using and the flit.

Here comes the question that I think for each router there should be at
most 5 input unit (from east ,west, north, south and cpu), but when I print
out input unit id, they are from 0 to 6, total 7 input units. I wonder
whether there is difference between input unit and input port.

Another question is flit is the smallest unit of request, I want to find
out which cpu sent out this request. So I tried to find the connection
between flit and request, when I looked at the flit class,  I cannot find
any request pointer, but message pointer which also does not tell the
source of the flit. Is there anyway to find out the source cpu id of the
request which is entering the current router in "route_req" method.

Thanks,
