Distributed Code Jam Practice Round is on!
By Swistakk, history, 8 years ago, In English

Hello. It has proved to be not well known that there is currently going DCJ practice round! Everybody who is going to participate should take a part in it to familiarize with distributed environment! Here it is: https://codejam.withgoogle.com/codejam/contest/6264486/dashboard Info about it was written in a mail which looked like it doesn't contain any interesting info, so probably most users disregarded it and don't know about those rounds. Thanks to zholnin for letting me know!

    Compilation flags can be changed in the dcj/config.json file.

Has anyone managed to get the local testing tool working on Ubuntu with a C++ solution? All I get is a bunch of undefined references to MyNodeId() etc. :(

    I have no idea why, but change #include "message.h" to #include <message.h> (the same goes for problem_name)

      You can keep #include <message.h> and #include <problem.h>. dcj.sh will automatically include all header files from the includes-folder. So simply move problem.h into this folder. message.h will already be there.

    You can do the same way we did last year: Build it yourself (with zeus and message included, both .h and .c files). Then use PARunner tool to run it manually.

    I build it with MSVC 2013, then run like this:

    parunner.exe -n=2 -trace_comm=false -stderr="tagged" DGCJ.exe

    These are just example options. works like a charm..

    PARunner is in one of subfolders. Swistakk should be especially happy to use it, because some of the messages it prints are in Polish :)

    From Google Code Jam discussion group:

    From: Pablo Heiber 	
 
Hi Artsem,

Thanks for checking in. We are still working on trying to make it happen. We had a dependency cease to exist so we are doing some reworking of the system to get around that. If we can have it fully tested before the weekend (we are trying), we will put up a new practice round. This is likely not going to start before Thursday, though.

Best,
Pablo
