In that case you should raise the memory limit to something quite high. I'd suggest to start with 2GB and increment this to 2.5 and 3 GB if it doesn't work yet. That's because the Java VM pre-allocates a lot of memory. With cgroup support this is not an issue, but without you have to add that overhead to the memory limit. Then you also have to change the value of MEMRESERVED in the java compile script executable you use (java_javac_detect by default). > > If you're trying to enable cgroups, then make sure to follow the instructions in the administrators manual.

Hello, First I think domjudge is amazing, i like it and i want congratulations for your work I have a few questions, 1- Version 5.2.0, do you know when will be stable. 2-Can i include another files in the problem, for example i have a main file .c and this main file has a file fichero.h to include data in file main or another file with functions to include in main file to use. 3- Can I upload and submmit more than one exercise at the same time, for example i have two exercises A and B. 4- the same that point 3 but in the jury system execute more than one exercise at the same time. Thanks kind regards.

To what size did you raise the memory limit? Try to raise it at least to 2GB if you're not using Linux cgroups. Unfortunately, the way that memory is reserved by the JVM and counted (using resource limits) by Linux often requires such huge amounts. Therefore we strongly recommend using cgroups: that measures only memory really used by the JVM and requires more reasonable overhead.

Changes from Munich
by Stefan Toman 07 Mar '16

07 Mar '16

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Dear DOMjudge developers, first of all thank you for writing DOMjudge. We are using it at TU München, Germany, for many courses and competitions. Having more than 100 contests and 50.000 submissions by 1000 teams we changed many parts of the system and created a fork of your project. We would like to contribute our changes to DOMjudge if you are interested in them. You can see our website for instance at https://judge.in.tum.de/conpra (other sections are available at the top left corner of every page). The sources we use are available at https://git-judge.in.tum.de/icpc/tumjudge. We will create merge requests in case you are interested in our changes. We would do some things a little different when we don't work in our fork. For instance, we created new css and javascript files to avoid conflict when merging your changes. These are the main features we added to the system: * a modern layout based on bootstrap with a nicer menu bar and form controls * teams can also view, download and edit their submissions as jury members can do it already * an overview of points throughout all contests a team participated in, grouped by similar contest names * bonus points can be awarded to teams for individual problems and contests * the statistics page generates some LaTeX commands to include detailed statistics into solution slides * problems have additional fields author, difficulty, topic and source and there are filters for these fields * write access to user and team accounts can be restricted for admins (We run several DOMjudge instances for several courses since we don't want lecturers of different courses to adjust the system as they need it. User accounts are shared via a MySQL replication, which makes user data read-only for all but one instance, all other data, including roles, is not shared.) * links in the menu are customizable in the settings * scoreboards can be shuffled in case you don't want to reveal which problems were solved (see contest 6 at the link given above for an example) * the judge instances are integrated into our website, the news system and the account system of the university (probably nothing that somebody else would need) We also created a framework to create random test data for problems from some seeds. This allows us to run failing submissions of teams on small random inputs until we find one that makes their submission fail. That way, we usually find much smaller inputs that are easier to debug. These scripts can be called from the jury backend and the output is also included into the backend. We hope there are some changes that may be interesting for you. If this is the case please tell us. We can tell you more about what we did there and would like to contribute the corresponding changes. Best regards, Stefan -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQEcBAEBAgAGBQJW2BppAAoJEBKwZA1x2vm6qNUH/RyzQ5BjZdbkkHnRMAiELQHH NTfeSK8Sl5BXXYNPyQ4YmVR3o6NrcCkh5hVzkJzUb7e9Zw+2FRhBVA5OK0MxmOcr syOCXdQXuITNPYdbn4i5gJwdjvaKJmR0r/IFd7kyfuBG4EdbDjo1Au52IxD10p8H pEpa6wwcsuW1jKk78c/EQ8cUnL0uw8T/2KtAvsHh2/siKOecZscZw7/wA3hKHUPx gK4e9wjZ6xbA2Di8HH0zreL8OBPhLH2qNkLdKuzVhYKoFzVXM2UUWMOXN4WQVq0x XH2DfXzoCOC2iWTEeJ7ZVXg0l0isl6LfzFQ5Mbnkd7PmiEBhYSChJkd/cum30e4= =gH0q -----END PGP SIGNATURE-----

moving to a PHP framework
by Jaap Eldering 05 Feb '16

05 Feb '16

Hello all, During/after the hackathon of 24 January the issue was raised that the codebase of DOMjudge is getting more and more complex and that it would be a good plan to move to a PHP framework to separate code and HTML layout via templating and using an ORM to abstract away the database. The discussion was initiated in a github issue here: https://github.com/DOMjudge/domjudge/issues/198 and I'm attending everyone here to it. If you have any experience with PHP frameworks such as Symfony, Laravel, or others, feel free to chime in, or even help with some initial testing to determine which framework to choose. Jaap

Output limit
by Br. Anand Shenoi 19 Dec '15

19 Dec '15

Hi All, What is the difference between the output limit in the global settings and that in the problem wise setting? When we set the Output limit for a specific problem, it gives TLE. If the output limit for the same problem is not set, it never exits from the memory. the status shows "JUDGING". It means, the global output limit is not being considered by DOM. Can anyone help please?

Hi Jaap. There is a situation. Suppose if a solution has been submitted, but that solutions is not even passing the first test case and the program doesn't terminate.

Here is an error from a java program: Program error output Exception in thread "main" java.lang.UnsupportedClassVersionError: SimilarStrings : Unsupported major.minor version 52.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(ClassLoader.java:800) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:142) at java.net.URLClassLoader.defineClass(URLClassLoader.java:449) at java.net.URLClassLoader.access$100(URLClassLoader.java:71) at java.net.URLClassLoader$1.run(URLClassLoader.java:361) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at sun.launcher.LauncherHelper.checkAndLoadMain(LauncherHelper.java:482) The JDK in Judgenode is 1.8 whereas chroot in domjudge is fetching only 1.7. Any way to resolve this error?

Time specific for a problem & Global time limit
by Br. Anand Shenoi 14 Dec '15

14 Dec '15

Guys, A doubt: There is a "time limit" for each problem. There is a "time limit overshoot" in Configuration Settings. Does it mean that if we set the "time limit overshoot" as more than the maximum time limit for one of the problems in the contest, it will affect the others with the lower time limit? For example: Contest 1 has 5 problems 4 problems have 1 sec time limit. Rest 4 has 4 sec time limit. And let us say one of the submissions for 1 sec problem set goes into infinite loop. Will the problem exit as per 1 sec time limit for that problem or will I wait for the 4 sec global "time limit overshoot"?

Dear admin, I am a student at University of Information Technology, I'm going to use Domjudge to organize our contest (ACM), I followed your Admin Manual Installation Guide, but I always get error when install Domjudge: -- Before, I get error about jsoncpp-devel. Then, I add --disable-submitclient in configure line. This was not happened. -- After, when I run make, I get error about symbol in /usr/lib/libm.so. File in wrong format. -- Then, I followed Install again, I check url /share/domjudge/www/jury => it a white page. I think I have some mistake when install, but I sure that I followed all of you tutorial. So, can you help me to install this? I'm using CentOS 6.7 with Kloxo installed.

Hi, I cannot log in with the default data admin/admin http://isc.unsaac.edu.pe/cuscontest/public/login.php but when I do this through curl it seems to be working fine: curl --data "login=admin&passwd=admin&cmd=login" http://isc.unsaac.edu.pe/cuscontest/public/login.php what could be the reason for this behaviour, hope you can help me. BTW it was working fine before, I cannot realize why it suddenly took this behaviour, the domjudge version is 4.0.5 and I'm using this version of ubuntu. ubuntu@ip-172-31-28-85:~/domjudge-4.0.5$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.2 LTS Release: 14.04 Codename: trusty ubuntu@ip-172-31-28-85:~/domjudge-4.0.5$ -- Best Regards. Dennis Huillca Portilla <http://about.me/dennisbot>

See http://randspringer.de/boost for more documentation. configure: error: Boost not found (required for checktestdata) ubuntu@ip-172-31-28-85:~/domjudge-4.0.5$ my question is, why I didn't get that error with my previous installation?. my current ubuntu version is: ubuntu@ip-172-31-28-85:~/domjudge-4.0.5$ lsb_release -a No LSB modules are available. Distributor ID: Ubuntu Description: Ubuntu 14.04.2 LTS Release: 14.04 Codename: trusty ubuntu@ip-172-31-28-85:~/domjudge-4.0.5$ and the domjudge version is 4.0.5 the same version I've used the last time I've succesfully installed on other ubuntu pc. hope you can explain it a little if that boost is required, I've installed the compilers as described ni the documentation. -- Best Regards.
