How can I participate in the BOINC Pentathlon?
Every team should be signed up by a contact person using this registration form until 2 May 2020. The credits of all team members at the Pentathlon projects will be counted, so team members do not need to sign up individually.

I registered my team for the Pentathlon, but it does not appear in the list of registered teams.
That page is updated manually, hence there may be some delay.

How are the projects chosen?
To make the Pentathlon as exciting and trouble-free as possible while at the same time maintaining a maximum of flexibility, all five projects are chosen by a small group of the organizers this year.

Where and when are the projects announced?
On the fifth day (Marathon and one other discipline) or on the third day (Sprint, Javelin Throw, and one other discipline) prior to the start of the discipline on the main page, via Blog, and RSS feed. While the Marathon project is announced exactly five days in advance at 0.00 UTC, the announcement of the other projects are possible at 0.00 UTC, 6.00 UTC, 12.00 UTC, or 18:00 UTC to compensate for geographical advantages. Regardless of the time of the announcement, all disciplines start and end at 0.00 UTC.

When do the disciplines start?
The exact time for each discipline will be announced together with the project. In addition, each day of Javelin Throw is announced three days in advance. Therefore, no team will know the complete Pentathlon schedule in advance.

How does the Marathon work?
The Marathon is running during the whole Pentathlon. The team with the most credits earned at the specified project during the 14 days wins.

How does the Sprint work?
Running for only three days, the Sprint is the shortest discipline. It will be run at a CPU or GPU project that provides work units with a quorum of 1 to make sure that credits are granted as fast as possible. The team with the most credits earned at the specified project during the specified period wins.

How does the City Run work?
The City Run is a discipline with the well-known duration of five days and will take place at a CPU project. The team that earns the most credits wins.

How does the Cross Country work?
The Cross Country will also run for five days, but possibly at a GPU project. The team, that earns the most credits, wins.

What is Javelin Throw?
Javelin Throw consists of five days, the credits are counted for each day separately. The rankings are based on each team's third best daily score. It will be run at a CPU or GPU project that provides work units with a quorum of 1 to make sure that credits are granted as fast as possible.

How are the overall stats calculated?
In each discipline, overall points are awarded for the first 30 teams with credits according to this table. Teams that received no credits in a discipline do not get any points for the overall score in this discipline. The team with the most overall points from all five disciplines wins the Pentathlon.

What happens in case of a tie in the overall stats?
Tied teams are ranked by their head-to-head comparison. Example: Team A finishes the five disciplines ranked 4th, 1st, 2nd, 2nd, 1st, while Team B finishes ranked 2nd, 2nd, 3rd, 1st, 2nd. Hence, both teams reach 450 points. However, Team A wins, as it was ahead of Team B in more disciplines than vice versa.

When are the stats updated?
The overall stats and the stats for all running disciplines are updated on the hour.

Do work units downloaded prior to the start of the discipline count? How about pending credits?
Credits granted while the discipline or a day of Javelin Throw is running are counted. It does not matter when the work unit was downloaded. Also, pending credits cannot be taken into account.

What happens if a project's server breaks down and stats cannot be updated?
This can be a problem if it happens at the start or end of a discipline or of a day of Javelin Throw. Only credits granted after the first successful update after start and before the last successful update before end of the discipline can be counted. So, if you want to make sure that your credits are counted, you should return them after the first successful stats update (check the time of the last update on the respective discipline stats page) but well in advance of the end.

Are there individual user stats?
No, the Pentathlon is a team competition. Hence, there are only team stats.
