System Trial Image

System Trial Image

We provide a installer image to build a Linux system similar to the environment that will be used in ICPC 2023 Yokohama regional contest.

Notable Differences Between the Trial Image and the Actual Machine in the Contest

The actual linux system provided in the contest is slightly different from the system provided by the trial image here. The computing environment in the contest is as follows.

  • The user and password are different from icpc-trial:icpc-trial here.
  • You can’t get the root access.
  • There is no Internet access. You can only access to the contest system through the web browser.
  • CLion activation code is placed at the desktop.
  • A command to print your source code is provided.


It is strongly recommended that you install the trial system to virtual machines. The installer may not work in some hardware for issues like missing drivers.
The installer clears all data on local disks. Please make sure all data is backed up specially if you try installation on real hardware.
