[gem5-users] gem5 v20.1.0.1 Hotfix Release [Garnet Network Model]

2020-11-06 Thread Bobby Bruce via gem5-users

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 this fix to the stable branch, marking the release of gem5
v20.1.0.1.

Those using the Garnet Network Model are strongly encouraged to pull this
largest release from the gem5 stable branch :
https://gem5.googlesource.com/public/gem5

Kind regards,
Bobby

Thanks Kyle!  Another good reason for us to get the GCN3 tests up and
running as part of kokoro soon :)

[AMD Public Use]

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 gem5. Different compiler maybe? The change 
that broke this for me literally just moves files around so I have no ideas how 
that caused it to break.

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 build.

And I think the dockerfile needs some update. The scons requires python3.6 to 
compile gem5, to be specific, `python3-config` need python3.6, but the default 
version installed with the docker is 3.5.

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 
up to date version is on the develop branch until the next gem5 release.

[CAUTION: External Email]
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 this problem:
Program Started!
info: running on device
info: architecture on AMD GPU device is: 801
info: allocate host mem (  7.63 MB)
info: launch 'vector_square' kernel
panic: panic condition availableTokens > maxTokens occurred: More tokens 
available than the maximum after recvTokens!
Memory Usage: 1737788 KBytes
Program aborted at tick 137231963000

Is there anything I did incorrectly?

Thanks!
Best, Yichen

To be specific, I use the following command:
## build docker
docker build -t gcn3-test gem5/util/dockerfiles/gcn-gpu
## make gem5
docker run --rm -v $PWD/gem5:/gem5 -w /gem5 gcn3-test scons -sQ -j$(nproc)

 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 build.

 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 up to date version is on the develop branch until the next gem5
 release.

 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 this problem:

 Program Started!
 info: running on device
 info: architecture on AMD GPU device is: 801
 info: allocate host mem (  7.63 MB)

 tokens available than the maximum after recvTokens!
 Memory Usage: 1737788 KBytes
 Program aborted at tick 137231963000

 Is there anything I did incorrectly?

 Thanks!

 Best, Yichen

 To be specific, I use the following command:

 ## build docker
 docker build -t gcn3-test gem5/util/dockerfiles/gcn-gpu
 ## make gem5
 docker run --rm -v $PWD/gem5:/gem5 -w /gem5 gcn3-test scons -sQ

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.

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"

2020-11-06 Thread Poremba, Matthew via gem5-users

[AMD Public Use]

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 
up to date version is on the develop branch until the next gem5 release.

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 this problem:
Program Started!

Is there anything I did incorrectly?

To be specific, I use the following command:
## build docker
docker build -t gcn3-test gem5/util/dockerfiles/gcn-gpu

[gem5-users] How to use checkpoint for a specific code in the Gem5 full system mode.

2020-11-06 Thread Hasan, S M Shamimul via gem5-users

Hello.

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

===
build/X86/gem5.opt --debug-flags=DRAM --debug-file=trace.out 
configs/example/fs.py --disk-image="/home/cosmogan-image/cosmogan" 
--kernel="/home/gem5/pkr_cp/other/vmlinux-4.9.238" 
--script="/home/gem5/pkr_cp/other/tmp.sh"


My "tmp.sh" file contains the following code.

#!/bin/sh
/sbin/m5 checkpoint
cd /cosmoGAN/networks
python run_dcgan.py
/sbin/m5 exit


The problem is the "trace.out" file that I got contains lots of memory traces 
that I do not need (e.g., system boot related memory trace). I need memory 
traces for only the following code "python run_dcgan.py." How can I get it? 
Please let me know. Thanks a lot in advance.

Sincerely,
S.M.Shamimul Hasan

[gem5-users] Re: Setting up cluster for gem5

2020-11-06 Thread Daniel Gerzhoy via gem5-users

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
program you are running)
I exclusively use Syscall Emulation mode, so that may not apply in Full
System.

*It is however single-threaded. So if your entire group is running many
experiments at the same time make sure you have a ton of cores.*

2) As for job management, I created my own system for
configuring/running/parsing etc.that I've built with python.

gem5 as of recently has been shipped with dockerfiles. I use the gcn3
dockerfile for instance. I'd recommend using them.
Again I use a custom solution here, but I'm pretty sure container job
management is a solved problem. I think one of them is "kubernets" (see
https://kubernetes.io/)
I don't have experience with anything like that, but I'm sure that would be
useful.

Also, if you plan on editing gem5 and your sourcecode is going to be
located on the cluster, I'd recommend using code-server (
https://github.com/cdr/code-server)
It broadcasts an instance of vscode to a web page that you can access from
anywhere. I used to use gvim and bash scripts and it was hell. Code server
was a life-saver.

If you (or anyone else) already have a solution for editing code on the
cluster I would be interested in what it is.

Good luck!

Hi Huayi,

I suggest you to have a look at the following documentation:

This should be a good starter as it covers the SMT case 

Hello!

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 and adjust gem5 under 
fs mode. Anyway, here is my question that how should I do to modify DTS 
document to achieve my goal? Or is there any information or data that could

My group is in the process of upgrading our cluster and since many of us

they would like to share about the process for a smooth gem5 operation.
Mainly I am concerned about 2 issues:
