[gem5-users] How to calculate CPU execution time from output of PARSEC benchmark in FS mode

[VAIDYA ROHINI VILAS via gem5-users]

Hello,
I want to calculate CPU execution time for stream cluster algorithm in PARSEC 
benchmark.
I have its output stats file.
CPU execution time = (CPU clock cycle ) * (Clock cycle time)
for CPU clock cycle I have taken count of sim_ticks in third region (please 
correct me if I am wrong) .
please suggest me which parameter should I take to calculate clock cycle time  .
Thank you.

 I am using following command :
"time build/ALPHA_MESI_Two_Level/gem5.opt configs/example/fs.py  
--cpu-type=TimingSimpleCPU

Which command I should add to run my binary file.
or there is any steps that i have to perform to run binary file of my code in

Hi Vaidya.

You have to mount the disk image that you are using for FS simulation with the 
compiled binaries that you want to add. After that, you can run your simulation 
and run the binaries either in interactive mode or with the --script argument 
when you launch the simulation (the same way you point to a disk image or a 
kernel). I recommend that you download both the kernel and the disk image from 
this https://www.gem5.org/documentation/general_docs/gem5_resources/ link. Get 
the "parsec" disk image and the corresponding kernel for it.

Un saludo,
Miguel Antonio Avargues Gutiérrez.

Hi Miguel,

For X86 full system simulation, specifically for creating custom disk
image that runs with newer Linux kernels, I believe gem5-resources has
the resources for that. More details can be found here,
- General introduction and artifacts:
https://www.gem5.org/documentation/general_docs/gem5_resources/ [1]
- Source code: https://gem5.googlesource.com/public/gem5-resources [2]
- Detailed instructions:
https://gem5art.readthedocs.io/en/latest/tutorials/boot-tutorial.html#creating-a-disk-image
[3] and 
https://gem5art.readthedocs.io/en/latest/tutorials/npb-tutorial.html#creating-a-disk-image
[4]


- From link [1], you can find built disk images, which could be
manipulated to suite an experiment.
- From link [2], you can find examples of building disk images for
some benchmarks such as npb, parsec, gapbs and spec.
- Link [3] and link [4] offer some explanation of what happens when
the disk images are built. The same website
(https://gem5art.readthedocs.io/en/latest/) also has tutorials for
other benchmarks and there are outdated links to GitHub (which were
moved to [2]). We are working on updating the website.


Regarding compiling util/m5, the new command to compile it is
```
scons build/x86/out/m5
```
where "x86" could be replaced by other ISA.


I hope this helps.

Hoa Nguyen

Hi,

I believe this is an error produced by a Python script. If the
configs/example/fs.py file has been modified, please check the
indentation of the modified part of the script for indentation
inconsistencies (for example, space indentations vs tab indentations).

There's something wrong with the disk image path you are providing:

file:///home/coep/gem5%202/full_system_images/aarch-system-201901106

As a general rule, I recommend you to double check if you are actually pointing 
to a valid guest binary.
For example, if you do

$file file:///home/coep/gem5%202/full_system_images/aarch-system-201901106,

what do you get?

To a disk image within the directory.

There's something wrong with the disk image path you are providing:

file:///home/coep/gem5%202/full_system_images/aarch-system-201901106

As a general rule, I recommend you to double check if you are actually pointing 
to a valid guest binary.
For example, if you do

$file file:///home/coep/gem5%202/full_system_images/aarch-system-201901106,

what do you get?

To a disk image within the directory.

The ARM in --cmd should be lower case.

Hi Krishnan,

There is also a native NVM model in gem5 now. See 
http://www.gem5.org/2020/05/27/memory-controller.html for details.

Also, though not as well integrated with gem5, there is VANS from UCSD: 
https://github.com/TheNetAdmin/VANS

Cheers,
Jason

Hi Krishnan,

In a project for class, I updated some code for NVmain so that it will at least 
run with the current commit of gem5. You can find it here: 
https://github.com/samueltphd/NVmain

I haven’t touched it since the course completed, so there are probably some 
updates that can be done to it still, so feel free to take the work and 
update/modify it. :)

Best,
Sam

Hi all,
I have been using gem5 for some time and interested in experimenting with non 
volatile memory. I found a couple of github projects on gem5 and nvmain 
integrations but they are very old. I just want to check with the community if 
there are any new additions to gem5 which makes non volatile memory a part of 
the project. Would be happy to learn more about this.
Thank you all.
