[Domjudge v5.1.3] : About how to apply executable checker for judging problem solutions
by Bình Dương, Tran 07 Oct '17

07 Oct '17

Dear Sir, There are some problems which have multiple solutions and it's necessary to apply executable checker for them. I've got some checkers from problem sources but I don't know how to link the checker with related problem in DomJudge. I think I should create a new executable item for a checker, but I don't know how to. Please, give me some advice. P/S: I attached here some checkers on my side Regards, Thank you -- [image: Điện thoại: (04) 37687717 – Máy lẻ: 100] <http://Email:%20linhpt@fpt.edu.vn/> Thanks & Best regards ------------------------------------ *TRẦN BÌNH DƯƠNG * Giảng viên bộ môn Công Nghệ Phần mềm Trường Đại học FPT Tel: (04) 37687717 – Máy lẻ: 104 Mobile: 0936 168 165 Email: duongtb(a)fe.edu.vn _______________________________________________________________________ The information in this e-mail and any attached files are CONFIDENTIAL and may be legally privileged or prohibited from disclosure and unauthorized use.

Hello everyone! Is it possible to run the live version of DOMjudge with Java 1.8? If so, how? Since we only get Java 1.7 running. Sincerely yours, Peter

About: helping me to solve the problems with DomJudge

Hi, I'm from FPT University in Viet Nam. I'm a coacher of ACM Teams in my university this year. I installed DomJudge successfully ( including domserver and judgehost ) and work with them well. But I faced with two following problems: 1. The judgehost isn't able to judge with Java Code. (I attached an image for the problem) [image: Hình ảnh nội tuyến 2] 2. I still don't know how to set custom_checking script in case of some special problems in a contest which contains statements indicate that it has multiple optimal solution depending on developer. Could you explain and give me an example for that case. ( I can't find any explicit example ) My Best Regards, -- [image: Điện thoại: (04) 37687717 – Máy lẻ: 100] <http://Email:%20linhpt@fpt.edu.vn/> Thanks & Best regards ------------------------------------ *TRẦN BÌNH DƯƠNG * Giảng viên bộ môn Công Nghệ Phần mềm Trường Đại học FPT Tel: (04) 37687717 – Máy lẻ: 104 Mobile: 0936 168 165 Email: duongtb(a)fe.edu.vn _______________________________________________________________________ The information in this e-mail and any attached files are CONFIDENTIAL and may be legally privileged or prohibited from disclosure and unauthorized use.

JAVA cgroups help
by 이정진 10 Sep '17

10 Sep '17

Hi. I set cgroups for java, but it does not work and I have some ask. I proceeded to install cgroups as follows the manual 3.17. ======= sudo apt-get install libcgroup-dev sudo edit /etc/default/grub GRUB_CMDLINE_LINUX_DEFAULT="quiet cgroup_enable=memory swapaccount=1" sudo update-grub sudo reboot and I checked the cmdline. cat /proc/cmdline print is BOOT_IMAGE=/boot/.. ~~ ro quiet cgroup_enable=memory swapaccount=1 next sudo ./configure >>During the execution of this command, I confirmed the following message. *use Linux cgroups...: yes sudo make build sudo ./misc-tools/create_cgroups and then, I run judgedaemon. However, judgedamon displays the message "Not using cgroups". ======== Can you tell me where I made the mistake? thanks.
