Hello,
I was reading the adminstrators manual and I have a question about the
section about setting up a judgehost:
https://www.domjudge.org/docs/admin-manual-3.html#ss3.7
It recommends the 'swapaccount=1' kernel parameter, but that made me
wonder if you actually want swap on a judgehost. I'm not fully familiar
with how Linux processes and swap work in detail, but say a judgehost is
judging a random submission while the RAM of the host is almost
exhausted. If the memory is swapped to disk to clear space for the
memory allocated by the submission, doesn't that potentially heavily
impact the run time of the submission? And if that's true, wouldn't you
see a TIMELIMIT that is not fully justified, because while you might not
exceed CPU time, you will exceed wall time?
I hope you can shed some light on this.
Regards,
Wim
Dear Mr. Jaap,
We are currently having problem with 20+ of testcase our judging process
is running slow. In debugging process, we found out that process of API
Call in fetching config and testcases is 5 to 7 seconds each. The
compiling and executing process has no problem in time manner. Do you
have suggestion where we can fix about this ?
Regards,
Andrew Jauhari
