PrimeGrid Aussie, Aussie, Aussie! Oi! Oi! Oi! Summer Solstice Challenge

#1 Ungelesener Beitrag von gemini8 » 09.12.2019 20:50

Moin.
Leider ohne Übersetzung. Habe momentan keine Ressourcen frei, deshalb nur die offizielle Einladung von PrimeGrid nach der Kurzfassung:
Donnerstag morgen um 04:19 UTC geht es mit GFN-21, GFN-22 und GFN-DYFL (Do you feel lucky?) los.
Welcome to the Aussie, Aussie, Aussie! Oi! Oi! Oi! Summer Solstice Challenge

The team scores. The crowd roars. You jump out of your seat, the happiest you've felt since those days during the summer of '98 you spent on Marley Beach, the savory smell of the barbie teasing your hungry stomach and the deep blue eyes of your now-ex-husband reassuring you that everything would be alright. Things were simpler then.
As you feel the sweet sting of sweat in your eyes under the hot Australian sun, you pity anyone who might be suffering under the height of winter in some poor, less fortunate part of the world. Across the stadium, someone shouts:
"Aussie Aussie Aussie!" OI! OI! OI!
"Aussie Aussie Aussie!" OI! OI! OI!
"Aussie!" OI! "Aussie!" OI!
"Aussie Aussie Aussie!" OI! OI! OI!

PrimeGrid will be celebrating the Summer Solstice by running a 10-day challenge with all the GFN projects where a prime is yet to be found; 21, 22 and DYFL. The Challenge will run from December 12th 04:19:00 UTC until December 22nd 04:19:00 UTC.

These GFN projects are part of the challenge:
GFN-21
GFN-22
GFN-DYFL
To participate in the Challenge, please select one or more of those projects in your PrimeGrid preferences section.


Note: The deadline for some of these WUs is significantly longer than ten days, so make sure your computer is able to return the WUs within the challenge time-frame. Only tasks issued AFTER the start time and returned BEFORE the finish time will be counted.


Application Builds
  • IMPORTANT: Overclocking -- including factory overclocking -- on Nvidia GPUs is very strongly discouraged. Even if your GPU can run other tasks without difficulty, it may be unable to run GFN tasks when overclocked.

    Supported platforms:
    *Windows: Nvidia GPU (OpenCL): 32 bit, AMD/ATI GPU (OpenCL): 32 bit, CPU: 64 bit, 32 bit
    *Linux: Nvidia GPU (OpenCL): 32 bit, 64 bit, AMD/ATI GPU (OpenCL): 32 bit, 64 bit, CPU: 64 bit, 32 bit
    *Mac: Nvidia GPU (OpenCL): 64 bit, AMD/ATI GPU (OpenCL): 64 bit, CPU: 64 bit, 32 bit

A Cautionary Reminder
  • ATTENTION: The primality programs Genefer (for CPUs) and GeneferOCL (for GPUs) are computationally intensive; so, it is vital to have a stable system with good cooling. It does not tolerate "even the slightest of errors." Please see this post for more details on how you can "stress test" your CPU, and please see this post for tips on running GFN on your GPU successfully.

    As with all number crunching, excessive heat can potentially cause permanent hardware failure. Please ensure your cooling system is sufficient.

    GFN-21 WU's are currently averaging 12 days on CPU and 20 hours on GPU.
    GFN-22 WU's are currently averaging 69 hours on GPU.
    GFN-DYFL WU's are currently averaging 54 hours on GPU (shorter not because WU's are shorter, but because the project self-selects for faster hardware).
    For a general idea of how your GPU stacks up, you can have a look at the fastest GPUs list.

    If your CPU is highly overclocked, please consider "stress testing" it. Overclocking your GPU is not recommended at all for GeneferCUDA. Sieving is an excellent alternative for computers that are not able to run Genefer. :)

    Please, please, please make sure your machines are up to the task.
Multi-threading optimization instructions

If you're running GFN-21 on a CPU and looking to maximize your computer's performance during this challenge, or when running LLR in general, you may find this information useful.
  • *Your mileage may vary. Before the challenge starts, take some time and experiment and see what works best on your computer.
    *If you have an Intel CPU with hyperthreading, either turn off the hyperthreading in the BIOS, or set BOINC to use 50% of the processors.
    • *If you're using a GPU for other tasks, it may be beneficial to leave hyperthreading on in the BIOS and instead tell BOINC to use 50% of the CPU's. This will allow one of the hyperthreads to service the GPU.
    *Use GFN's multithreaded mode. It requires a little bit of setup, but it's worth the effort. Follow these steps:
    • *Create a app_config.xml file in the directory C:\ProgramData\BOINC\projects\www.primegrid.com\ (or wherever your BOINC data directory is located). For a quad core CPU, the file should contain the following contents. Change the two occurrences of "4" to the number of actual cores your computer has.

      [pre]<app_config>
      <app_version>
      <app_name>genefer</app_name>
      <cmdline>-nt 4</cmdline>
      <plan_class>cpuGFN21</plan_class>
      <avg_ncpus>4</avg_ncpus>
      </app_version>
      </app_config>[/pre]

      *After creating the file, click on "Options/Read config files". You should then restart BOINC or reboot.
      *The first time BOINC downloads a GFN task, it may act a little strange and download 4 tasks instead of 1. The run times on this first set of tasks may look a bit strange too. This is normal. This will also occur anytime BOINC downloads more than one task at a time. This can be avoided by setting "Use at most [ 1 ] % of the CPUs" before you download GFN tasks. After one task was downloaded, increase the percentage.
      *Some people have observed that when using multithreaded GFN, hyperthreading is actually beneficial. We encourage you to experiment and see what works best for you.
Time zone converter:
  • The World Clock - Time Zone Converter

    NOTE: The countdown clock on the front page uses the host computer time. Therefore, if your computer time is off, so will the countdown clock. For precise timing, use the UTC Time in the data section to the left of the countdown clock.
Scoring information
  • Scores will be kept for individuals and teams. Only work units issued AFTER December 12th 04:19:00 UTC and received BEFORE December 22nd 04:19:00 UTC will be considered for credit.

    In this challenge we will be using the same scoring algorithm as we use to determine BOINC credits, including bonuses!. Because the score bonuses are included in the challenge score, it is advantageous to run the longer tasks if you can manage to finish them within the 10 day challenge window. This will land you a higher position in the leaderboard and therefor a higher score on the overall leaderboard.
At the Conclusion of the Challenge
  • We kindly ask users "moving on" to ABORT their WU's instead of DETACHING, RESETTING, or PAUSING.

    ABORTING WU's alows them to be recycled immediately; thus a much faster "clean up" to the end of a challenge. DETACHING, RESETTING, and PAUSING WU's causes them to remain in limbo until they EXPIRE. Therefore, we must wait until WU's expire to send them out to be completed.

    Please consider either completing what's in the queue or ABORTING them. Thank you. :)

    For those of you who wish to continue to help with GFN sieving, we are still sieving n=22 (World Record Units), as well as the n=20 (short) range and n=21 (next short) range. Please see We need your help with GFN Sieving! for more information.
More information on Generalized Fermat Numbers and the Genefer program Best of Luck to everyone!

Ich hasse die UTC-Angaben und bei der krummen Anfangszeit hilft mir der Counter im Browser auch nicht wirklich :worry:

Da ich zum RaceStart mal wieder auswärts bin, muß ich das Rennen Batch-gesteuert beginnen. Richtige Startzeit wäre dann wohl Donnerstag, 12.12 Morgens um 05:19 Uhr unserer Zeit, richtig ?

Supporting BOINC, a great concept !

Richtig !
Gut dass ich Frühschicht habe, zu der Zeit sitze ich dann eh vor'm Rechner :wink:
LG,

Würde Tschernobyl heute passieren, würden viele Menschen erstmal anzweifeln, dass es Atome überhaupt gibt.

Ich habe die Challenge heute per Twitter angekündigt und um Teilnahme in unserem Team gebeten.
Ich selbst werde diesmal leider nicht dabei sein können.

Michael.

Eine letzte große Leitung im alten Jahr!
Von vierzehn teilnehmenden Rechenkraftlern haben elf einen Platz, der in die individuelle Jahreswertung eingehen wird, zwei liegen im Bereich der TOP 100, zwei hätten es fast in letztere geschafft, und das Team hat mit dem elften Platz erneut eine gute Plazierung!
Vielen Dank allen Teilnehmenden!

Für die, die es interessiert:
Meldet euch für den internen Bereich 'Taskforce' an, und ran an die Formula Boinc!
