Dear all,
In the gem5 v20.1.0.0 release there was a bug in the Garnet Network Stats,
which adversely affected the overall behavior of the Garnet Network Model.
The bug, and related fix, are discussed here:
https://gem5-review.googlesource.com/c/public/gem5/+/36416. On November
6th, we applied
Thanks Kyle! Another good reason for us to get the GCN3 tests up and
running as part of kokoro soon :)

Hi Daniel,
I tried with your building command and at least it is working fine for me.
Thanks!

Hi all,
I am using gcn3-gpu docker running on ubuntu16.4 host machine. And follow
the gem5-resources/readme to build the application.

Hi Matt,
I also see the getdents error with square building gem5 with gcc 7.5.0.
I would hope we wouldn't have to define a variable in scons to get a syscall to
work. I am not sure where is SYS_getdents / SYS_getdents64 are supposed to be
defined, but it is not anywhere in
Ok, we’re using the same, but haven’t gotten the second error ... strange.
Are you using different apps?

Hi Daniel & Yichen,
What OS are you using? We have not encountered either of these problems
thus far ... something must be different about your setup and ours.
Thanks,

For some reason that syscall is only built if you set a flag. Recompile the
simulator like so:
scons -j$(nproc) build/GCN3_X86/gem5.opt --ignore-style SLICC_HTML=True
CCFLAGS_EXTRA="-DSYS_getdents -DSYS_getdents64"

Looking into that syscall error now.
I'm not quite sure yet how to fix the docker image since python 3.5 is the
latest version available for the distro needed. For now I disabled the check
for 3.6 since it seems unnecessarily strict and doesn't break anything related
to this
Thanks!
I tried the develop branch. But running into new problems

Hi Yichen,
Based on the changes I see you've made, it seems like you are using an older
version of gem5. These should all be fixed, including the error you are
seeing, on the tip of develop.
Keep in mind GCN3 was not officially part of the gem5 20.1 release, so the most

Hello.
I am running the Gem5 in full system mode. I am using the following command.

Hi,
I was trying to run gem5 with its GCN3 GPU model following the instructions
on https://www.gem5.org/documentation/general_docs/gpu_models/GCN3.
I fixed some bugs in the code but still cannot run the example. I attached
commands and bugs I fixed below.
The simulator launched and running into
Thank you so much for your reply, Daniel! It is really helpful.

Hey Shehab,
I've been working with gem5 on my group's research cluster for a while now.
1) Gem5 isn't very memory hungry in my experience, sometimes long
simulations (I'm talking 3 weeks+) will start bloating to GB of RAM but
its usually not paging so it doesn't slow things down (depends on the
Hi Huayi,
I suggest you to have a look at the following documentation:
https://elixir.free-electrons.com/linux/latest/source/Documentation/devicetree/bindings/cpu/cpu-topology.txt
This should be a good starter as it covers the SMT case
Kind Regards

Hello All,
My group is in the process of upgrading our cluster and since many of us
are using gem5 I was wondering if anyone has experience or recommendation
they would like to share about the process for a smooth gem5 operation.
Mainly I am concerned about 2 issues:
1) Required hard disk and
Hello!
I sent an email few days ago to question how to perform SMT functions on
gem5, the answer back to me the DTS does not mean to support SMT at the
moment. I’m new to Linux kernel development and my current goal is perform
DTS on gem5’s CPU so that can function as SMT. In this way, I can debug
