Hoa,

I just ran the system monitor on my Jetson Orin Nano, and it says I have 8G of 
RAM. I think I should be in good position to work the problem.

Hi Nick,

You can use the argument like this,

scons build/RISCV/gem5.opt –limit-ld-memory-usage -j`nproc`

I was able to compile gem5 with docker with 6GiB of RAM, and was not able to do 
that with 4GiB of RAM.

I think you already hint at a better solution, which is to use build the docker 
image on a different machine, and bundle the gem5 binary to the docker image. 
Then you can distribute the image to the Jetson.

Hoa Nguyen

installation procedure and see where it ends up.

Hi Nick,

I don't think there would be any problem with compiling gem5 on arm (or riscv) 
architecture on Ubuntu. I've been compiling/using gem5 on an arm system and it 
works for me.

However, please make sure that the system has enough memory to compile gem5. 
Typically compiling gem5 takes a lot of memory, and you can pass 
"--limit-ld-memory-usage" to reduce the memory consumption.

Hoa Nguyen

That sounds like a workable solution. I need to hunt down an large memory ARM 
system for that. I wanted to set up something like that so I don’t have to have 
the class go through a shaky install procedure.

Hoa,

Thank you for your suggestion. The Jetson Orin Nano normally comes with 4Gbyte 
Ram, so I can see that it could be a problem. Where do you apply the 
–limit-ld-memory-usage command? Did you attempt to build it with the docker 
command? I am using the Jetson Orin Nano for GPU and openmpi work, so the 
docker approach would help isolate the system. I am going to work through the 
installation procedure and see where it ends up.
