How can I participate in the BOINC Pentathlon?
Every team should be signed up by a contact person using this registration form until May 28, 2016. Late entries are accepted until June 2, 2016, but their project suggestions cannot be taken into account, because we want to inform the project administrators as early as possible. 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?
Every team can enter four project suggestions signing up. The projects suggested most often are assigned to the discplines according to this description.

Where and when are the projects announced?
5 days (Marathon, Swimming, City Run, Cross Country) or 3 days (Sprint) before the start of each discipline on the main page, via Blog, RSS feed, Twitter, and Facebook.



When do the disciplines start?
The exact time for each discipline will be announced together with the project. 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 project that provides work units with a quorum of 1 to make sure that credits are granted as fast as possible. The project might be either a CPU-only project or a project with GPU applications. 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 at a CPU-only 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 the project might be CPU-only or also support graphics cards. The team, that earns the most credits, wins.

What is Swimming?
Swimming is a discipline with a duration of seven days at a CPU-only project. The team, that earns the most credits, wins.



How are the overall stats calculated?
In each discipline, overall points are awarded for the first 30 teams with credits according to this table. 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 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. 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.
