The default weight based routing selects the free VC.
If so, then why I need to do the VC partitioning as you mentioned in the
Torus network.
*VC Selection (VS)*: The winner of SA selects a free VC (if HEAD/HEAD_TAIL
flit) from its output port.
I think this is a very important issue for
Hi Faisal,
The Torus topology deadlocks as it has rings in each dimension unless one
implements a VC partitioning scheme or bubble flow control. That's why I
removed torus from the default topologies provided by garnet2.0. If you
implement torus, you will have to implement deadlock freedom.
I want to ask about PerfectSwitch. PerfectSwitch is a router or arbiter?
http://www.m5sim.org/Simple
And Why PerfectSwitch need to have routing table?
I know PerfectSwitch has Round Robin scheduling to choose a virtual network
perform and the switch will see the message destination.
But Why it
Thanks Jason!
I see that this option called ports and it does work.
Is there any other impact of this option on the implementation or only on the
transition_per_cycle ?
About the example, on my case it should be split to at least 2 different
clocks, but I understand the cases that 2 transition
Thanks a lot for reply.
This is little bit terrible news for me.
However, as far I know garnet1.0 don't have the deadlock issue with Torus.
Please let me know how can I implement a VC partitioning scheme. Is it
possible?
I can configure the routing algorithm with particular channel selection,
Hello,
I'm a new gem5 user and simulating the coherent protocol of MESI with two level
of caches.
I see on the ProtocolTrace log file that several transition of the same address
can occur at the same cycle.

Hi everyone,
I am using gem5 that simulates an architecture that takes some information
from a core and passes into the Network Interface. I use Mesh topology and
Two-Level MESI Protocol. I use ruby and garnet for my memory and
interconnect modelling.
My need is to bypass L1 cache for data

The lectures on NoC deadlocks on my website might help understand the problem:

Dear All,
I like to simulate the synthetic traffic analysis for Torus for 256 nodes
with uniform traffic.
However, the network is showing latency degradation after 0.14 injection
rate (flit latency = 33.044985 for 0.14 and flit latency = 38.244770 for
0.13 ), which could be the possible case of
