Rules

This page summerizes the rule changes with respect to last year's Pentathlon as well as the rules regarding how the Pentathlon works, the disciplines and projects, the overall score and the statistics. It should go without saying that the goal of participating in the Pentathlon is to advance the projects and the own team. Any behaviour that intentionally harms the projects or other teams devalues the Pentathlon and may lead to consequences from the organizers, the other participants or the project administrators.

Modifications

2018

  1. As with the Sprint, the projects and times for two further disciplines will be announced only three days before their start instead of five days.
  2. The Sprint will definitely take place at a CPU project this year because no GPU project with Quorum 1 is available.

All teams should sign up for the Pentathlon until 27 April 2018 using this registration form. Subsequent submissions are possible until 02 May 2018, but the project suggestions can not be taken into account.

The BOINC Pentathlon starts on 05 May 2018, 00.00 UTC, and ends on 19 May 2018, 00.00 UTC. So, it will run for exactly 14 days.

No team will know the complete Pentathlon schedule right from the beginning! The exact time and the project for each discipline are announced 5 days (Marathon and one other discipline) or 3 days (Sprint and the two remaining disciplines) before their respective start on the main page and via Blog (Feed , Twitter , Facebook ). While every discipline starts and ends at 00.00 UTC, the projects may be announced at different times (00.00 UTC, 06.00 UTC, 12.00 UTC, 18.00 UTC) to avoid that some teams are always surprised in their sleep.

The disciplines differ in runtime and possible projects. For example, the Marathon runs during the whole Pentathlon, while the Sprint lasts only three days. Hence, at any time at least one discipline will run, but often different disciplines will run simultaneously.

The BOINC Pentathlon consists of 5 disciplines:

  1. Marathon (CPU, 14 days)
  2. Sprint (CPU, 3 days)
  3. City Run (CPU, 5 days)
  4. Cross Country (GPU, 5 days)
  5. Swimming (CPU, 7 days)

Each team may suggest four Projects while signing up. The projects are assigned to the disciplines as follows:

  1. Marathon
    • The project is set by the organizers.
  2. Sprint
    • The project with the most votes that provides workunits with a quorum of 1.
  3. City Run
    • The CPU project with the most votes that is not already chosen for Marathon or Sprint.
  4. Cross Country
    • The GPU project with the most votes.
  5. Swimming
    • The CPU project with the most votes that is not already chosen for another discipline.

Quorum 2 Asteroids@home**

*: If ODLK is chosen, either –ě–Ē–õ–ö or OLDK1 will be scored in consultation with the project administrators.
**: Asteroids@home is listed as a CPU project because, in contrast to other GPU projects, a GPU is barely more powerful than a CPU.

Projects are not eligible if they

  • were chosen in last year's Pentathlon (Cosmology@Home, Einstein@Home, LHC@home, World Community Grid, yoyo@home)
  • can not provide a sufficient number of workunits
  • do not support at least Windows and Linux
  • provide non-CPU-intensive (NCI) applications
  • use buggy or test-only applications
  • do not allow the creation of new accounts
  • do not support WebRPC

To keep it as transparent as possible, we will publish the suggestions of every team when announcing the final project.

For the overall score, points are awarded in every discipline to the best 30 teams that received credits. The champion of a discipline collects 100 points. The exact distribution of points:

The team which is able to collect the highest number of points in all 5 disciplines will win the BOINC Pentathlon. This also means that the champion may get a maximum number of 500 points.

In case of a tie in the overall score, the tied teams are ranked by their head-to-head comparison. Hence the team which is placed better than the other teams in more disciplines is ranked higher.

Of course, also the champions of the single disciplines are being honored. Therefore teams have the possibility to reach for the pedestal in a single discipline if they don't see a chance for themselves to succeed in the overall placings. In the end, they are being honored as well.

Only the statistics on https://www.setigermany.de/boinc_pentathlon/statistiken/pentathlon.php are considered to award points and choose the champions. They are based on data provided by the projects via WebRPC and are updated every hour.

A race day will start and end at 0:00 UTC (also known as GMT).

If a project's server is unreachable at the starting time of a discipline, only credits granted after the first successful statistics update will be counted. Likewise, the last successful statistics update will be the final result, if the server is unreachable at the ending time of the discipline.
