Compilation of Submissions

During the contest, teams will submit proposed solutions to the contest problems to the Judges using the DOMJudge contest control system. Source files submitted to the Judges will be compiled using the following command line arguments for the respective language:

  • C:
gcc -g -O2 -std=gnu11 -static ${files} -lm
  • C++:
g++ -g -O2 -std=gnu++17 -static ${files}
  • Java:
javac -encoding UTF-8 -sourcepath . -d . ${files}
  • Python 3
pypy3 -m py_compile ${files}
  • Kotlin
kotlinc -d . ${files}

The "${files}" in the above commands represents the list of source files from the submission which will actually be compiled. Files with the following suffixes (and only files with these suffixes) will be submitted to the compiler:

  • For C submissions: files ending with .c
  • For C++ submissions: files ending with .cc, .cpp, .cxx, or .c++
  • For Java submissions: files ending with .java
  • For Python submissions: files ending with .py
  • For Kotlin submissions: files ending with .kt

Execution of Submissions

For each language, if the above compilation step is successful then the submission will be executed as follows:

  • For C/C++:  the executable file generated by the compiler will be executed to generate the output of the submission.  
  • For Python 3: the main source file will be executed by the PyPy3 Python3 interpreter to generate the output of the submission.
  • For Java: the compiled main class will be executed using the following command:
java -Dfile.encoding=UTF-8 -XX:+UseSerialGC -Xss64m -Xms1920m -Xmx1920m
  • For Kotlin: the compiled main class will be executed using the following command:
kotlin -Dfile.encoding=UTF-8 -J-XX:+UseSerialGC -J-Xss64m -J-Xms1920m -J-Xmx1920m

Compilation and execution as described above will take place in a "sandbox" on a dedicated judging machine.  The judging machine will be as identical as possible to, and at least as powerful as, the machines used by teams.  The sandbox will allocate 2GB of memory; the entire program, including its runtime environment, must execute within this memory limit.  For interpreted languages (Java, Python, and Kotlin) the runtime environment includes the interpreter (that is, the JVM for Java/Kotlin and the Python interpreter for Python).

The sandbox memory allocation size will be the same for all languages and all contest problems.  For Java and Kotlin, the above commands show the stack size and heap size settings which will be used when the program is run in the sandbox.

Build Instructions

Instructions for building a system identical to what is planned for team use at the World Finals are posted here.  Please note that the image created by these instructions is a draft, subject to changes as we approach the World Finals.  See the Revised  list at the bottom of that page to determine the most recent change date.

Reference Materials

These packages will be available on team machines at the World Finals, and will be installed automatically as part of the steps listed under Build Instructions, above. 

We welcome all suggestions and comments.  This configuration is subject to change until the final update.  All questions about the system configuration should be directed to John Clevenger, ICPC Technical Director.
