Hi, I have a problem when I try to run multi-core judgedaemon. I followed your document. I setup cgroups, edit etc/cgroup-domjudge.conf: -- Change cpuset.cpus = 0 => cpuset.= 0-22; I also add file misctools/create_cgroups to /etc/cgconf.d/cgroup-domjudge. After that, I check /cgroup/cpuset/domjudge/cpuset.cpus => Output is 0-23. I also build runguard after I config cgroups. But I only can run 8 judgedaemon. From judge 9th, if it compile any code, I will receive this error: Compiling failed with exitcode 255, compiler output: /domjudge/judgehost/bin/runguard: illegal user specified: 7809 Try `/domjudge/judgehost/bin/runguard --help' for more information. I set all user is user that I run domjudge. But judge 8 judge can compile well. Please help me! Thank you!
