@MacTin I see AdminWebServer 0 is shutting down in the output. Normally, you should be starting cmsResourceService -a (see the docs) and leave it running. In the process list, you'll see various CMS services. You can use e.g. screen to keep cmsResourceService running at all times.

Thank you, the cms system is working .

@MacTin
Is there examples about Contests,
MacTin
@MacTin
or, where can i find example tasks?
Andrey Vihrov
@andreyv
@MacTin The simplest way is just to create the tasks yourself. For example, you can use the AdminWebServer interface to create a "Sum" task where, given two numbers, you need to output their sum. After setting task type (Batch) and limits, you can add it to a contest, and then the task will appear in the contestant interface.

A while ago I made a step-by-step tutorial for deploying cms on Google Cloud Platform. It's a little bit out of date, but can be useful for starting up from scratch.

Is the current tps loader compatible with ioi-2017/tps? I am getting some key errors when trying to load the examples there..
MacTin
@MacTin
Thanks Andrey Vihrov@andreyv, I can watch the cms working very well, but I have to learn more about it , is there any book? or Resources?

Hello!
I am facing a problem. The ranking web server is not updating the scores for OutputOnly Tasks. However, the 'Ranking' page in admin web server shows the correct scores.
I have tried dropping the ranking web server's data and restarting the contest + ranking web server, still the same issue. The ranking web server is updating all other tasks' scores but not the output only.
What could be the problem?
I am on version 1.4.rc1.
Score Type for the OutputOnly Task is 'Sum'. If it matters.
Andrey Vihrov
@andreyv
@RezwanArefin01 First check ProxyService and RWS logs for anything suspicious

Hi, I have installed CMS and created a new contest as described in the documentation. However I can't add any tasks since none are available in the 'select new task' drop down menu on the web admin page. Have I made a mistake in installation?
AutocompleteFailed
@AutocompleteFailed
I have subsequently worked out how to import the example contest with its tasks.
Does CMS have support for the Learning Tools Interoperability protocol?
Andrey Vihrov
@andreyv
@AutocompleteFailed First you need to create a task under Tasks, then you can add it on the contest page

Ah, that was a bit silly of me. Thank you

Please, help me, about the problem shoes of ioi 2019

It has this score and test cases

{"score": 10, "testcases": ["1-01", "1-02"]}
{"score": 20, "testcases": ["1-01", "1-02", "3-01", "3-02", "3-03", "3-04", "3-05", "3-06", "3-07", "3-08", "3-09", "3-10", "3-11", "3-12", "3-13", "3-14", "3-15", "3-16", "3-17", "3-18", "3-19", "3-20", "3-21", "3-22", "3-23", "3-24", "3-25", "3-26", "3-27", "3-28", "3-29", "3-30", "3-31", "3-32", "3-33", "3-34", "3-35", "3-36", "3-37"]}
{"score": 20, "testcases": ["1-01", "1-02", "3-01", "3-02", "3-03", "3-04", "3-05", "3-06", "3-07", "3-08", "3-09", "3-10", "3-11", "3-12", "3-13", "3-14", "3-15", "3-16", "3-17", "3-18", "3-19", "3-20", "3-21", "3-22", "3-23", "3-24", "3-25", "3-26", "3-27", "3-28", "3-29", "3-30", "3-31", "3-32", "3-33", "3-34", "3-35", "3-36", "3-37"]}

But when I Try to set the score paramters the cms shoy error as "invalid fromat"

Anyone knows how I upload that type the problem in de cms?

RezwanArefin01
@RezwanArefin01
You need to format the test cases separately to import in cms.
The score parameters in CMS works like this:
If you give [[m1, t2], [m2, t2]], it means first t1 tests have point m1, next t2 tests have point m2.

@AutocompleteFailed Depends on how you started it, if you ran cmsResourceService, then type Ctrl+C to interrupt it

hi, everyone, is it possible to configure the BatchTask to link to a xxx.a libraray during compliation?
Andrey Vihrov
@andreyv
@liangfeng-source You can add a grader source file to be linked together with user code, see https://cms.readthedocs.io/en/latest/Task%20types.html#batch
liangfeng-source
@liangfeng-source
@andreyv hi, Andrey, thank you for the reply. But my problem is: our grader is not a "xxx.c" source file, but a "xxx.a" library, we need to use -l commend to link the source file to it.
gcc -I . contest.c libxxx.a -o contest
something like this.
I want CMS to allow me to configure my batch task like this.
is it possible
Andrey Vihrov
@andreyv
@liangfeng-source Is there any reason not to supply the grader in source format?
I don't think there is a ready way to use a static library, but you could hack CMS so that .a is allowed alongside .c/.cpp as a grader
liangfeng-source
@liangfeng-source
@andreyv the grader is too complex. it contains too many files to be included in a single file.
hacking CMS can be a good idea. Also I found out that they allow to implement "Custom task types". Have you used this?
Andrey Vihrov
@andreyv
@liangfeng-source: You could try to concatenate your files when preparing the batch task. Something like this: cat *.h > grader.h, cat *.cpp > grader.cpp, and then upload grader.h and grader.cpp as graders
liangfeng-source
@liangfeng-source
OK, I will check this.
how about the “Custom task types”
do you think it will work if I implement my own task types?
Andrey Vihrov
@andreyv
Yes, you could also create a custom task type. Copy cms/grading/tasktypes/Batch.py, modify it as needed (look for GRADER_BASENAME, you need to allow the .o extension) and register it in setup.py. I don't know if it would work, e.g., you also need to ensure that the user source comes before your library in the language compilation command. Also there is a problem that .o is not discernible if you have multiple programming languages enabled.
In general, this would be a "hack"
