spend too much time to run an experiment

[ckf104]

Hello, I am now trying to reproduce experiments result in CloudLab. But the program in fig6bc has run over five hours. Is it usual case? Here is some information.

$ps -eo etime,cmd | grep main
   05:00:28 sudo stdbuf -o0 sh -c ./main /users/chenkefa/AIFM/aifm/configs/client.config                            18.18.1.3:8000
   05:00:28 sh -c ./main /users/chenkefa/AIFM/aifm/configs/client.config                            18.18.1.3:8000
   05:00:28 ./main /users/chenkefa/AIFM/aifm/configs/client.config 18.18.1.3:8000
   00:00 grep main
$ls -l  # in the dir fig6bc

The content of log.1331 is the same as the description of README.txt , but log.2218 is still empty. By the way, how long is every experiment expected to run?

Hi ckf104,

I just tried it out in my machine. The result comes out fairly quickly---around 5 mins, please see the log below. Have you tried to kill the processes in both machines and rerun the experiment? I'm willing to assist if you find it reproducible at your end.

Thanks for the kind response.

I have rebooted two machines and faced the same situation. I have done the following operations since I logged into cloudlab machines.

1. Install the softwares requested in the Readme in two machines
2. Run build_all.sh to build AIFM in two machines
3. Change the configs/ssh file only in node0 and make sure node0 can connect node1 without password by ssh.
4. Run fig6bc/run.sh only in node0 and find above described result.

A weird thing is that I find following extra terminal output when running test.sh and run.sh

{: Command not found.
}: Command not found.
{: Command not found.
}: Command not found.

There shouldn't be any error when executing test.sh or run.sh. I guess something is not configured right on your machine. If you could grant me the permission to access your cloudlab machine, I'll ssh into it and take a look. My public key can be found here https://github.com/zainryan.keys

I have added the public key into two cloudlab machines. You can log in by following command if I doesn't make a mistake:)

ssh -p 22 chenkefa@hp022.utah.cloudlab.us # node 0
ssh -p 22 chenkefa@hp005.utah.cloudlab.us # node 1

And may need to reconfig ssh service to connect node 1 in node 0 without password. Really thank you for the kind help!

Okay, I see what's going on. Simply change the default shell into bash and you're ready to go. All scripts in this repo are written for bash. I'll leave a note in README.

I've done the modification on your machines and I can get the result fairly quickly without any issue.
