Unable to run rntop

[okyspace]

Hi, I have issue running rntop.

This is my setup:

1. I have a ubuntu22.04 VM that runs the rntop docker container.
2. I have a host that simulate the GPU machine that I want to monitor.

• I can ping the host from my VM as well as SSH from VM to host.
• I am able to run docker run -it --rm -v $HOME/.ssh:/root/.ssh --entrypoint bash runai/rntop -c "ssh user@machine nvidia-smi". From the README, it means that the container can connect to the machine and it's the rntop application itself that can't.
• When I proceed by adding --ssh to the rntop command, i.e. sudo docker run -it --rm -v $HOME/.ssh:/root/.ssh --entrypoint bash runai/rntop:latest user@machine, it fails. I have error "GPUs wmove() failed. Terminate called after throwing an instance of 'std::expression'. In the printed output, there is no cluster and nodes info printed out too.

I am not sure how to further troubleshoot, any advice? Thanks

Hi @okyspace!
First of all, sorry for the late reply, for some reason my GitHub notification didn't work well and only now I saw this issue.

rntop uses ncurses for the GUI.
Unfortunately, rntop does not support all window configurations properly.

My guess is that what you are seeing is related to your window size.
Try to increase the window size and see if things change.
In addition to that, rntop is not responsive to UI changes, so also make sure to not change the window size when running.

Let me know if it worked or not.
