A test necessary for large contests which uses a single server, multiple instances pattern of judgehost deployment.
Modified from domjudge/judge.
- Reboot to get a clean kernel state.
- Run createcgroups.sh to create domjudge cgroups.
make- Adjust
TASKSin run.py. python run.py, wait and see load, process states and judgescale output. Please be patient, and if possible run it at least for 1 hour.- After test you could run
clean.shto clean created domjudge subcgroups (domjudge cgroup itself will NOT be removed).
If you see load >= 2 * TASKS, you are doomed.
Example 1:
(32 cores KVM, 20 tasks, ~45min, Linux 5.15, load >= 40)
It's strongly recommended to use Linux 6.3+ as your judgehost kernel. Otherwise, you are probably doomed.
