I really appreciated the fact that a member of the Garnet development team
responded to my inquiry. Thanks a lot.
Further, I really need to get an XYZ routing for the 3D topology because my
target is to control traffic flow at the bridge links by using suitable buffer
occupancy threshold settings.
I attempted to used gdb debugger to check the variables in the first five
lines of codes in the RoutingUnit::outportComputeXY() function, but received
error message as shown beneath the command lines below.
gdb ./build/Garnet_standalone/gem5.opt configs/example/garnet_synth_traffic.py
--network=garnet2.0 --num-cpus=16 --num-dirs=16 --topology=Prism_Mesh
--mesh-rows=4 --sim-cycles=5000 --injectionrate=0.02 --synthetic=uniform_random
--routing-algorithm=1
gdb: unrecognized option '--network=garnet2.0'
Use `gdb --help' for a complete list of options.
How should I use gdb to recognize the optional parameters?
In addition, I suspect if one can split the m_router along the z-axis and treat
each level individually, a working XYZ routing can be obtained from the XY
routing.
Can you help with that?
It is a pleasure to interact with great minds.

Hi,
I have been using the kernel and image provided in the gem5 download page. When
I put “/sbin/m5 dumpresetstats 0 1”, I was expecting a periodic dump every 1000
tick. But stats.txt shows “sim_ticks
1198037940 # Number of ticks s”. How can I fix it or is
it a known bug?

Dear all,
I simulated the gem5 with full system mode and the command is "sudo
build/ALPHA/gem5.opt configs/example/fs.py
--script=./configs/boot/canneal_8c_simsmall.rcS --cpu-type=detailed --num-cpu=8

--nvmain-config=../nvmain/Config/RRAM_ISSCC_2012_4GB.config -F 5000000000 -I
2000000000” and get the stats.txt like below.
Then I use "python GEM5ToMcPAT.py stats.txt config.json template-x.xml” to
transfer the output files of gem5 to the available input of McPAT, named as
mcat-out.xml (the input of McPAT) here. But there have some warning here like
this"Reading GEM5 stats from: stats.txt

…...
I don’t know how to solve this warning and guess this is not the problem here
which lead to the error below. So I ignore them.
Then I use"./mcpat -infile mcpat-out.xml “ to run the McPAT, and can not get
the output of McPAT. The error also shown as "McPAT (version 0.8 of Aug, 2010)
is computing the target processor...
some value(s) of number_of_cores/number_of_L2s/number_of_L3s/number_of_NoCs
is/are not correct!”
Ps: I use the ubuntu14.04 LTS system and the McPAT in gem5/ext/mcpat file
All helps appreciate!
The output file of gem5 is too big to put here. You can get it with this link
https://drive.google.com/drive/folders/13yTj7gVtvi-mUjFUB16jgg2sAqmwSe3-?usp=sharing
<https://drive.google.com/drive/folders/13yTj7gVtvi-mUjFUB16jgg2sAqmwSe3-?usp=sharing>.
The template is used for transfer and the result of transferred(input of McPAT
tools) are listed here. Sorry to bother you guys.

Hello Ciro Santilli,
I can't reproduce on master, because I want to simulate a ScratchPad Memory
in gem5.
I download the gem5 from "https://github.com/markoshorro/gem5-spm"; ,but I
don't know where files different from gem5 master.
I can tell you that my compiler is gcc 6 and OS version is ubuntu 16.04.5
LTS.
Before I use this gem5-spm, I have some experience to use gem5 master, and
can successfully build full system.
I will try to run through GDB, get the backtrace.
Respectfully yours, Yo-Xian,Wang

Hi weizheng,
I used your mcpat-out.xml in our cMcPAT (and I guess that any McPATv1.3 is
equivalent) and it completed the process. Attached is the output at
print_level 5.
Best,
Andreas

My best advice is: do a git bisect to find the offending commit, and
report it to the autor (Mark?) directly, e.g. at

Subject: [gem5-users] 3D MESH TOPOLOGY DEVELOMENT IN GARNET2.0

I want to modify the Mesh_XY topology in Garnet2.0 to create a 3D topology. I
used Mesh_XY as a base layer to which a replicated layer is added with the
MakeTopology function. Then I established the necessary bridge links. It works
fine with table routing, but always produced a segmentation error when the XY
routing is applied. Can someone please help me out? I can attached my scripts
when asked to.
Thanks for your expected cooperation.

Table routing by default does XY for a 2D Mesh - since all X links have a
weight of 1 and Y links have a weight of 2. You can give weights of 3 for your
Z links to get a XYZ routing algorithm for instance.
The specific XY routing function inside Garnet only works for a 2D mesh as it
routes assuming link directions of N/S/E/W and will not work for your 3D
topology. I only recommend using it to study adaptive routing algorithms in a
2D Mesh for instance.
Cheers,
Tushar
