Less than ten months have passed since the seventh BOINC Pentathlon came to an end. Now the Pentathlon is back to its usual date from May 5 to May 19 and SETI.Germany invites all BOINC teams to compete in five disciplines at five projects for the eighth time.

This year, the stable and popular project World Community Grid is set for the City Run discipline, with only one subproject being considered for the Pentathlon.

The teams may enter their favorite WCG subproject and three additional project suggestions while signing up using the registration form at https://www.seti-germany.de/boinc_pentathlon/anmeldung.php until April 27. The suggestions will be taken into account in the project selection as described here. Late registration without project suggestions is possible until May 2.

All information about the BOINC Pentathlon is available at Pentathlon pages, while you can find the answers to many questions in the FAQ.

Looking forward to seeing you at the Pentathlon! :)

Dear fellow crunchers,

after a hacker had caused havoc on the server and the Pentathlon pages had been offline for one week, the BOINC Pentathlon 2016 has now been rescheduled to start one month later, i.e. on 05 June 2016 (see also this announcement). Registration for teams that wanted to participate but could not sign up in time is open again until 28 May.

The seventh BOINC Pentathlon is around the corner. As usual, SETI.Germany invites all BOINC teams to find out which team copes best with the challenges of five disciplines at five projects between May 5 and May 19.

While there are no major rule changes this year, it is ensured that there will be only one winner after the shared gold medal last year. Furthermore, the Pentathlon pages have undergone an optical refresh, all the rules and later on the stats are there, as well. Many questions are answered in the FAQ.

Each team that wants to participate can sign up and enter four project suggestions using this registration form until April 27. Later registration is possible until May 2, but without the possibility of suggesting projects.

Therefore, explore the interest within your team and sign up. We're looking forward to your participation in the BOINC Pentathlon! :)

I had a couple of jobs hitting the elapsed time limit, too. I observed that all those jobs had a very low estimated runtime and were downloaded shortly after the plan_class was changed. Now that the estimated runtime is more realistic, no more jobs are hitting the limit.

  • You will now see the camb_boinc2docker and planck_param_sims apps identified by the plan class "docker_vbox64_mt". This is a change to the name only and does not require any action on your part. Its more to let everyone know these are both running on the same Docker / Virtualbox based technology, which was not obvious otherwise.


No action required unless an app_config.xml like the one in the FAQ is used. ;)

After setting "Request tasks to checkpoint at most every xx seconds" to a value higher than the runtime of the task, I'm able to complete tasks on Win7 x64 with vbox 5.0.0. So the 'maximum disk limit exceeded' error is definitely caused by the checkpoint snapshots.

I agree with Crystal Pellet's point that a vbox_mt app should not use all available CPU cores, because normal priority can cause problems for other processes (e.g. GPU tasks) running in parallel. Unless you need fast results or plan to send out very large tasks which would take days on a single core, I don't see an advantage of a multi-threaded app at all.

Another remark: If there is any good measure for the actual computing power used to complete a task, you may consider using this for granting credit instead of CreditNew. With any credit system, there may be complaints that credits are too low, too high or both compared to project X (I personally don't care; cross-project comparison will always be apples and oranges, because the projects are calculating different things), but CreditNew has often lead to a credit lottery, leaving everybody unhappy who cares about his stats.

Thanks for the interesting stats.

I think that the OS efficiency comparison is biased towards older OSs. The Win Server 2k8, Vista, and some Linux machines may have been running for a number of years, while Win 8.1 was released just 2 years ago. Hence, the Win 8.1 machines had less time to accumulate credits. It would be better to compare only the credits awarded during the last month, although I don't know if there's an easy way to get this numbers (RAC is not a very good measurement either).

OTOH, Win XP machines had plenty of time to accumulate loads of credits, but they might be significantly less powerful than modern machines. The typical Win 8.1 host might also have a newer CPU than the typical Win 7 host, but CPUs did not become that much faster over the last couple of years, at least as long as new extensions like AVX are not used.

Once again, SETI.Germany invites all BOINC teams to the BOINC Pentathlon. For the sixth time, the winner is battled out in five disciplines at five projects between May 5 and May 19.

After the introduction of Marathon and Sprint in the last couple of years, there will be a new discipline in this year, again. Details will be announced prior to the beginning of the Pentathlon, for now I can reveal that it will run for at least five days at a CPU project.

Each team that wants to participate has to sign up using the registration form at http://www.seti-germany.de/boinc_pentathlon/anmeldung.php until April 27. The teams may suggest one GPU project and three CPU projects, please see this page for details.

All information is available on the Pentathlon page at http://www.seti-germany.de/boinc_pentathlon/22_en_Welcome.html, while you can find the answers to many questions in our FAQ.

Looking forward to seeing you at the Pentathlon! :)

For the fifth time, SETI.Germany invites all BOINC teams to the BOINC Pentathlon, a competition inspired by the Pentathlon in ancient Greece. Between May 5 and May 19, five disciplines at five different BOINC projects are held to find the overall winner.

Each team that wants to participate has to sign up using the registration form at http://www.seti-germany.de/boinc_pentathlon/anmeldung.php. Registration is open until April 27.

For all but the Marathon discipline, the teams may suggest their favorite project when signing up. A list of possible projects is available at http://www.seti-germany.de/boinc_pentathlon/25_en_Disciplines.html, you may suggest other projects as long as you think they are able to handle the increased load. Note that projects that were part of last year's Pentathlon are excluded for this year.

For more information including the full rules, please visit the BOINC Pentathlon page at http://www.seti-germany.de/boinc_pentathlon/22_en_Welcome.html.

Please spread the word and gauge the interest within your team. Looking forward to seeing you at the Pentathlon! :)
