Online Contest Operations Manual

This is the IOI 2022 Online Contest Operations Manual, applicable only for online teams. It specifies the procedures for online teams to participate in the practice and contest days of IOI 2022.

Communications

We will use Matrix for communication with all teams via their team leaders, deputy leaders, and proctors, which need to be logged in and reachable throughout the contest days. Communications will be done in the following rooms:

  • #ioi.announcements: general announcements on contest days.
  • #ioi.online: announcements / support for online teams.

Contestants should use the CMS for all queries during contests as far as is practicable. If it is necessary to communicate with the technical or scientific committee, they must request to do so via their proctors.

Contestant VM Accounts

We will distribute the contestant accounts with the official release of the contestant VM as specified in the release schedule in the Contestant VM Manual.

Information on how to get the contestant accounts will be announced on Matrix and email. Please check them regularly.

Practice Day

Teams must endeavour to have all their contestants and proctors participate in Practice Day. We will not be responsible for problems arising from their absence from this practice. Contestants will not receive any consideration during Contest Day 1 and Contest Day 2 for problems that should have been caught earlier had their respective teams fully participated in the Practice Day.

Teams are strongly encouraged to conduct practice at the actual venue they will use for Contest Day 1 and 2. Teams should also involve all their technical support staff, and test their backup contestant PCs, backup internet access, and other technical infrastructure.

The schedule relative to the on-site contest is as follows.

Contest Day 1 and Day 2

Teams must ensure that their contest venues are fully prepared and ready no later than 4 hours before the start of the contest. This includes turning on the contestant PC and ensuring that the contestant VM is running and connected to the IOI 2022 grading system.

If the local timezone makes this difficult, the contestant PC and contestant VM can be started at a convenient time the prior day, and ensuring that the contestant PC does not sleep, suspend, hibernate or power off. This time is essential for the technical committee to perform integrity checks and any necessary live updates of the contestant VM; and any delays may result in late start for the respective contestant.
