Facing the same issue here!
I also found that FuzzBench does more stuff when running on GCP, which makes it less robust. I cannot see logs from screen but have to visit GCP console to see log reporting, but I still cannot find the reason why FuzzBench stops working on GCP.
(I failed to run FuzzBench by setting a GCP project due to the error in #1911, so I am actually running local experiment on GCP VM instances)
It seems like
run_experiment
in GCP takes longer to generate a report. It has been more than 5+ hours since I started executing following command:for 2 trials, each of them lasting for 30 minutes, but it hasn’t finished generating report data. Running the same command and configuration in the local experiment already terminated.
The
run_experiment
is looping in this loop: https://github.com/google/fuzzbench/blob/ba22647276a63912312fb6636287cc266da19683/experiment/dispatcher.py#L166.It seems like the processes are sleeping for the majority of time.
htop
output also shows that measuring processes are getting scheduled, but there’s less than 1% usage of CPU for each scheduled process.Is there any solution to make it generate report faster?
run_experiment
script also steadily outputs this warning in case it is relevant.
