Edit: If changeing this numbers plausibly changes the resulting times you can have some confidence (not as good as inspecting the final assembly code) that the artificial benchma...
Epoch vs Iteration when training neural networks
...
@Bee No, take for example 10000 training samples and 1000 samples per batch then it will take 10 iterations to complete 1 epoch.

How to track child process using strace?
...ou can use strace, as @stackmate suggested.
strace -f -e trace=network -s 10000 -p <PID>;
or output it to a file.
strace -f -e trace=network -s 10000 -o dumpfile -p <PID>
-f for all forked process, -s for string size to print, and -o to dump the output to a file.

How to kill a child process after a given timeout in Bash?
...iter

}
Use like run_with_timeout 3 sleep 10000, which runs sleep 10000 but ends it after 3 seconds.
This is like other answers which use a background timeout process to kill the child process after a delay. I think this is almost the same as Dan's extended answer (...
