Question about running the hpca-2023 tutorial
I was reviewing the tutorial with the hope that I could setup something similar for a class that I am teaching at Johns Hopkins Whiting School of Engineering. Is there a way of running this locally on my linux system. I have gem5 installed, and it runs the basic routines described in the getting started documentation. When I try to run the tutorial I get the following error:
~/gem5$ build/X86/gem5.opt ../gem5-tutorial-codespace/materials/hello-world.py

Hello, same problem here.
I am using the Ubuntu 22.04 LTS and the latest gem5 stable version. I
followed the HPCA(23) video tutorial and even used the available git
codespace.
I removed the "resource" related code lines and used a variable
-> binary = "path_to_the_benchmark" <- to set the benchmark, and another
error occurred: "Attribute_Error: 'str' object has no attribute
'get_local_path' in the" -> '(86) set_se_binary_workload.py' -< file
After that I used the get_started scripts (part 1) and the benchmark worked
just fine.
The new Python API is very friendly but I could not use it.

Thiago,
I have had better luck working through the gem5 bootcamp 2022. I have run into some odd issues that I would love to compare notes with someone who knows the gem5 system. Some of the errors have to do with the directory organization of the gem5-bootcamp-env code from the github. I am running into python errors that suggest that the code is not able to find the python files. As an example when I run:
build/X86/gem5.opt /home/besernd1/gem5-bootcamp-env/materials/using-gem5/02-stdlib/complete/hello-world-with-unique-cache.py
I had to make some changes in the unique_cache_hierarchy_complete.py file because the python code could not see liCache.py. When I tried to run the hello-world example, it still does not see the python file. I also have to explicitly define the path to the customResource file, because it does not understand the abbreviated directory path provided.
I also ran into a problem with some of the earlier examples. I had to add a line in front of the m5.instantiate():
board._pre_instantiate()
m5.instantiate()
This was not necessary in later examples fro 02-stdlib.
Part of the problem has to do with the tutorial and bootcamp using the codespaces. I think we need clear instructions on how to do those examples with the basic gem5 installation.

Hi everyone,
The examples from the tutorial repo (
https://github.com/gem5-hpca-2023/gem5-tutorial-codespace) seem to work for
me with the gem5/gem5-resources versions checked out in that repo. I
basically cloned the entire repo using the --recursive flag. If you are
using a different version of gem5, my guess is that your scripts might need
to be updated because of changes in the standard library.

I installed gem5 prior to downloading the gem5-tutorial-codespace. Is the correct procedure git clone –recursive https://github.com/gem5-hpca-2023/gem5-tutorial-codespace? Should I have done that with the bootcamp 2022?
I use git to manage my class archive, but I normally keep it very simple.

Sorry for a very late reply, but for the sake of clarification:
Yes, I believe you should have cloned the bootcamp 2022 recurisively. I think both the issues highlighted in this thread were due to running a newer version of gem5 on top of older config scripts and resources which used the older API.
There wasn’t much that went wrong when we used the 2022 Bootcamp repo with a class of 50 last year. There may be bugs but I don’t think anything should be glaringly broken. I think we did the gem5 Bootcamp with v22.0 of gem5, and v22.1 was released in December of last year, so be careful. There were quite a few API chances between these released. The “Obtain_resources” change was definitely one.
I’m sorry for all the trouble your having with it. If you run into any additional problems please reach out to me directly.

Bobby,
Thank you for your reply. I am making my way through the Bootcamp 2022 videos and slides. So far everything seems to be working. I had already planned to use visual studio code as a student interface for GPU programming with the Jetson Orin Nano systems, so I will try to use that with the gem5 programming exercises. I have gem5 running on a VM system for my initial checkout, and we try to port it to the Jetson for the class.
Is there a change document that describes the API changes? I will take a look at the Obtain resources to make sure my examples are current. I don’t recall seeing anything odd yet.
I will have a challenge getting a week of viewgraphs down to two lectures, but my plan is to have a basic tutorial, a lecture on concurrency and coherence. and three discussion forums that will allow the student experiment and generate studies. This is an on line class, and I am integrating gem5 into a basic outline that follows Patterson and Hennessy’s book on Computer Architecture (A quantitative approach).
I think the only part of Gem5 that I could not get working was the GUI work. I don’t think it has been updated.

Yes, I believe you should have cloned the bootcamp 2022 recurisively. I think both the issues highlighted in this thread were due to running a newer version of gem5 on top of older config scripts and resources which used the older API.
There wasn’t much that went wrong when we used the 2022 Bootcamp repo with a class of 50 last year. There may be bugs but I don’t think anything should be glaringly broken. I think we did the gem5 Bootcamp with v22.0 of gem5, and v22.1 was released in December of last year, so be careful. There were quite a few API chances between these released. The “Obtain_resources” change was definitely one.
I’m sorry for all the trouble your having with it. If you run into any additional problems please reach out to me directly.

The examples from the tutorial repo (https://github.com/gem5-hpca-2023/gem5-tutorial-codespace) seem to work for me with the gem5/gem5-resources versions checked out in that repo. I basically cloned the entire repo using the --recursive flag.

Some of the errors have to do with the directory organization of the gem5-bootcamp-env code from the github. I am running into python errors that suggest that the code is not able to find the python files. As an example when I run:

I had to make some changes in the unique_cache_hierarchy_complete.py file because the python code could not see liCache.py. When I tried to run the hello-world example, it still does not see the python file. I also have to explicitly define the path to the customResource file, because it does not understand the abbreviated directory path provided.
I also ran into a problem with some of the earlier examples. I had to add a line in front of the m5.instantiate():
board._pre_instantiate()
m5.instantiate()
This was not necessary in later examples fro 02-stdlib.
Part of the problem has to do with the tutorial and bootcamp using the codespaces. I think we need clear instructions on how to do those examples with the basic gem5 installation.

Hello, same problem here.
I am using the Ubuntu 22.04 LTS and the latest gem5 stable version. I followed the HPCA(23) video tutorial and even used the available git codespace.
I removed the "resource" related code lines and used a variable -> binary = "path_to_the_benchmark" <- to set the benchmark, and another error occurred: "Attribute_Error: 'str' object has no attribute 'get_local_path' in the" -> '(86) set_se_binary_workload.py' -< file
After that I used the get_started scripts (part 1) and the benchmark worked just fine.
The new Python API is very friendly but I could not use it.

Hey Nick,
The GUI work was basically just a prototype. We had ambitions to properly incorporate it into the project but we lacked the resources to do so. It should really be archived until someone wants to revive it. So I’m not surprised it doesn’t work. We don’t recommend using it.
The RELEASE-NOTES.md file, in the root of the gem5 repository (https://gem5.googlesource.com/public/gem5/+/refs/heads/stable/RELEASE-NOTES.md) should highlight all the major changes introduced in gem5 released. API changes should be noted there.
A VM should work fine, but if you want to try something more light-weight, you could use Docker. The Docker image for the container we ran the Bootcamp in, via Codespaces, is gcr.io/gem5-test/gem5-tutorial-env:latest http://gcr.io/gem5-test/gem5-tutorial-env:latest. So all you need to do is:
docker pull gcr.io/gem5-test/gem5-tutorial-env:latest <http://gcr.io/gem5-test/gem5-tutorial-env:latest>
docker run -u $UID:$GID —volume <gem5 directory>:/gem5 —rm -it gcr.io/gem5-test/gem5-tutorial-env:latest <http://gcr.io/gem5-test/gem5-tutorial-env:latest>
# from here you’re in the docker container and the gem5 repo is mounted to “/gem5”
(The sources for this docker image is in the Bootcamp repo, here: https://github.com/gem5bootcamp/gem5-bootcamp-env/tree/main/docker).
Kind regards,
Bobby

Bobby,
Thank you for your reply. I am making my way through the Bootcamp 2022 videos and slides. So far everything seems to be working. I had already planned to use visual studio code as a student interface for GPU programming with the Jetson Orin Nano systems, so I will try to use that with the gem5 programming exercises. I have gem5 running on a VM system for my initial checkout, and we try to port it to the Jetson for the class.
Is there a change document that describes the API changes? I will take a look at the Obtain resources to make sure my examples are current. I don’t recall seeing anything odd yet.
I will have a challenge getting a week of viewgraphs down to two lectures, but my plan is to have a basic tutorial, a lecture on concurrency and coherence. and three discussion forums that will allow the student experiment and generate studies. This is an on line class, and I am integrating gem5 into a basic outline that follows Patterson and Hennessy’s book on Computer Architecture (A quantitative approach).
I think the only part of Gem5 that I could not get working was the GUI work. I don’t think it has been updated.

When I try to run the tutorial I get the following error:

Hi Nick,
For teaching you may be able to get some inspiration from my class
assignments. Specifically, assignment 5 is about coherence:
https://jlpteaching.github.io/comparch/modules/gem5/assignment5/
All of the code for my assignments can be found here under different
branches for each assignment:
https://github.com/jlpteaching/gem5-assignment-template
Cheers,
Jason

Hey Nick,
The GUI work was basically just a prototype. We had ambitions to properly
incorporate it into the project but we lacked the resources to do so. It
should really be archived until someone wants to revive it. So I’m not
surprised it doesn’t work. We don’t recommend using it.
The RELEASE-NOTES.md file, in the root of the gem5 repository (
https://gem5.googlesource.com/public/gem5/+/refs/heads/stable/RELEASE-NOTES.md)
should highlight all the major changes introduced in gem5 released. API
changes should be noted there.
A VM should work fine, but if you want to try something more light-weight,
you could use Docker. The Docker image for the container we ran the
Bootcamp in, via Codespaces, is gcr.io/gem5-test/gem5-tutorial-env:latest.
So all you need to do is:
docker pull gcr.io/gem5-test/gem5-tutorial-env:latest
docker run -u $UID:$GID —volume <gem5 directory>:/gem5 —rm -it
gcr.io/gem5-test/gem5-tutorial-env:latest
# from here you’re in the docker container and the gem5 repo is mounted to
“/gem5”
(The sources for this docker image is in the Bootcamp repo, here:
https://github.com/gem5bootcamp/gem5-bootcamp-env/tree/main/docker).
Kind regards,
Bobby

Bobby,
Thank you for your reply. I am making my way through the Bootcamp 2022
videos and slides. So far everything seems to be working. I had already
planned to use visual studio code as a student interface for GPU
programming with the Jetson Orin Nano systems, so I will try to use that
with the gem5 programming exercises. I have gem5 running on a VM system for
my initial checkout, and we try to port it to the Jetson for the class.
Is there a change document that describes the API changes? I will take a
look at the Obtain resources to make sure my examples are current. I don’t
recall seeing anything odd yet.
I will have a challenge getting a week of viewgraphs down to two lectures,
but my plan is to have a basic tutorial, a lecture on concurrency and
coherence. and three discussion forums that will allow the student
experiment and generate studies. This is an on line class, and I am
integrating gem5 into a basic outline that follows Patterson and Hennessy’s
book on Computer Architecture (A quantitative approach).
I think the only part of Gem5 that I could not get working was the GUI
work. I don’t think it has been updated.

Sorry for a very late reply, but for the sake of clarification:
Yes, I believe you should have cloned the bootcamp 2022 recurisively. I
think both the issues highlighted in this thread were due to running a
newer version of gem5 on top of older config scripts and resources which
used the older API.
There wasn’t much that went wrong when we used the 2022 Bootcamp repo with
a class of 50 last year. There may be bugs but I don’t think anything
should be glaringly broken. I think we did the gem5 Bootcamp with v22.0 of
gem5, and v22.1 was released in December of last year, so be careful. There
were quite a few API chances between these released. The “Obtain_resources”
change was definitely one.
I’m sorry for all the trouble your having with it. If you run into any
additional problems please reach out to me directly.

I use git to manage my class archive, but I normally keep it very simple.

Hi everyone,
The examples from the tutorial repo (
https://github.com/gem5-hpca-2023/gem5-tutorial-codespace) seem to work
for me with the gem5/gem5-resources versions checked out in that repo. I
basically cloned the entire repo using the --recursive flag. If you are
using a different version of gem5, my guess is that your scripts might need
to be updated because of changes in the standard library.

Thiago,
I have had better luck working through the gem5 bootcamp 2022. I have run
into some odd issues that I would love to compare notes with someone who
knows the gem5 system. Some of the errors have to do with the directory
organization of the gem5-bootcamp-env code from the github. I am running
into python errors that suggest that the code is not able to find the
python files. As an example when I run:
build/X86/gem5.opt
/home/besernd1/gem5-bootcamp-env/materials/using-gem5/02-stdlib/complete/hello-world-with-unique-cache.py
I had to make some changes in the unique_cache_hierarchy_complete.py file
because the python code could not see liCache.py. When I tried to run the
hello-world example, it still does not see the python file. I also have to
explicitly define the path to the customResource file, because it does not
understand the abbreviated directory path provided.
I also ran into a problem with some of the earlier examples. I had to add
a line in front of the m5.instantiate():
board._pre_instantiate()
m5.instantiate()
This was not necessary in later examples fro 02-stdlib.
Part of the problem has to do with the tutorial and bootcamp using the
codespaces. I think we need clear instructions on how to do those examples
with the basic gem5 installation.

Hello, same problem here.
I am using the Ubuntu 22.04 LTS and the latest gem5 stable version. I
followed the HPCA(23) video tutorial and even used the available git
codespace.
I removed the "resource" related code lines and used a variable
-> binary = "path_to_the_benchmark" <- to set the benchmark, and another
error occurred: "Attribute_Error: 'str' object has no attribute
'get_local_path' in the" -> '(86) set_se_binary_workload.py' -< file
After that I used the get_started scripts (part 1) and the benchmark
worked just fine.
The new Python API is very friendly but I could not use it.
