Subject: Re: [gem5-users] Run CPU 2006 benchmark on gem5 fs mode

Hi All,

I run this command on GEM5 and got nothing in the stats.txt

./build/X86/gem5.fast ./configs/example/fs.py --simpoint-interval 1000 
--mem-size=3GB --kernel=/home/abdkhail/linux4.19/vmlinux 
--disk-image=/home/abdkhail/ubuntu16.img --script=configs/boot/benchmark.rcS

benchmark.rcS

#!/bin/sh

cd 
/home/ubuntu/cpu/benchspec/CPU2006/473.astar/run/run_base_ref_amd64-m64-gcc42-nn.0000/astar_base.amd64-m64-gcc42-nn
/sbin/m5 dumpresetstats
/home/ubuntu/cpu/benchspec/CPU2006/473.astar/exe/astar_base.amd64-m64-gcc42-nn
echo "Done :D"
/sbin/m5 exit

Any help would be appreciated.

Best Regards

I think this should work fine to generate the *.bb.gz

Hi Dear Dimitrios,

I run the CPU2006 benchmark on gem5 in FS mode for 1000 instructions as follows:

The command is :

./build/X86/gem5.fast ./configs/example/fs.py --mem-size=3GB 
--kernel=/home/abdkhail/linux4.19/vmlinux 
--disk-image=/home/abdkhail/ubuntu16.img --script=configs/boot/benchmark.rcS 
--simpoint-interval 1000


The benchmark.rcS

#!/bin/sh

cd 
/home/ubuntu/cpu/benchspec/CPU2006/473.astar/run/run_base_ref_amd64-m64-gcc42-nn.0000/astar_base.amd64-m64-gcc42-nn
/sbin/m5 dumpresetstats
cd 
/home/ubuntu/cpu/benchspec/CPU2006/473.astar/exe/astar_base.amd64-m64-gcc42-nn
/sbin/m5 exit

I am wondering if that works well! any help or update would be appreciated.

Best Regards

I am not sure if this is possible in FS, at least not the same way you do in 
SE.  You will need to use simpoints in order to create checkpoints for you 
code.  After that you basically segment your code into smaller, say 1000000 
instructions per segment, which you can run.  Check the link I sent in my 
previous message.  However note that you will need to run the code for each 
benchmark  twice, once for generating the simpoint files and once to set the 
checkpoints.  For me this can take up to 4 week for the larger codes, and a few 
days for the smaller ones in SPEC CPU 2017.  Once you have the checkpoints 
though, it should take a couple of hours.  I don't know if there is a faster 
way to do this, maybe someone else has a better suggestion.

Hi Dimitrios, I appreciate your help. How I can run the benchmark for one 
million instruction in the FS mode. In SE mode I used -I 1000000 . Any help 
would be appreciated. Best Regards

Hi,

Here is an example of an .rcs script.  As Ciro told you, first you need to have 
a bootable image, optionally create a checkpoint after boot and finally add the 
benchmarks to the cd image.

#/bin/bash
cd 
/your/path/SPEC_CPU_2017/benchspec/CPU/627.cam4_s/run/run_base_refspeed_aarch64-64.0000
/sbin/m5 dumpresetstats
/yourpath/SPEC_CPU_2017/benchspec/CPU/627.cam4_s/exe/cam4_s_base.aarch64-64
/sbin/m5 exit

In the example above you simply cd to the directory of the benchmark you want 
to use and then run it.  /sbin/m5 dumperesetstats resets your statistics 
counters and exit is used to finish the execution.  Note I use spec 2017, which 
I found that it's best to run directly as I do above than use their 
infrastructure.  Problem is that FS is too slow and you waste a lot of time 
running their python scripts.  Also, I would encourage you to learn about 
simpoints<http://gem5.org/Simpoints> if you plan on running SPEC CPU 2006 with 
anything more than the test inputs.  Running with ref will take days/weeks.

Best,

Dimitrios Chasapis

The linked documentation runs an arbitrary benchmark of your choice.
You just have to add SPEC CPU to the image yourself as explained
there. I can't fully automate SPEC CPU build because it is closed source.

1. get Linux to boot, e.g.:
https://github.com/cirosantilli/linux-kernel-module-cheat/tree/657c59249e56d861bb0a437a1b1c757797281910#gem5-buildroot-setup
2. learn to checkpoint at the end of boot, restore, and run an
executable afterwards, e.g.:
https://github.com/cirosantilli/linux-kernel-module-cheat/tree/657c59249e56d861bb0a437a1b1c757797281910#gem5-run-benchmark
3. learn to add your own files to the image, e.g.:
https://github.com/cirosantilli/linux-kernel-module-cheat/tree/657c59249e56d861bb0a437a1b1c757797281910#add-new-files-to-the-buildroot-image
