Welcome to the PrimeGrid Leonids Challenge. After a short "321" countdown, spaceship Earth will be intercepting large numbers of Leonid meteors in a few days. During the mission, we want to direct spaceship Earth's idle computers to find some large "321" primes.
What you need:
What would help, but isn't absolutely necessary:
What won't help (but won't hurt either):
Work not downloaded and uploaded within the challenge will not be counted. Should you not be able to be in front of one or more computers at that time, see [post=29529001]the challenge strategy thread[/post] for ways to start and finish on time.
I plan to post stats in this thread, and others may too. But for the most up-to-date TeAm stats, get my user script. With that installed, visit this address for TeAm stats.
Good luck to all!
What you need:
- One or more fast x86 processors. (Even slow ones could probably do some work.)
- All of those processors running stably. The best way to check stability is to run Prime95's Large FFT test for a day or two. If you get any errors, your processor or RAM isn't stable enough for this challenge at your current clock/voltage. Or you might just need to blow the dust out of your case after a long hot summer where you didn't do much DC.
- Windows, Linux, or Mac OS 10.4+.
- BOINC, attached to PrimeGrid (http://www.primegrid.com/).
- Your PrimeGrid Preferences with "321 Prime Search (LLR)" the only CPU project selected in the Projects section.
- Patience! These are fairly long WUs. (Not as long as Seventeen or Bust, but each could take a day.)
What would help, but isn't absolutely necessary:
- An Intel processor with AVX. You won't get much extra BOINC credit with AVX, unfortunately, but you will get more race credit.
- Fast RAM. If you overclock your RAM, be sure to run the Prime95 test described above.
- A 64-bit OS may provide some small speed advantage.
- Reading [post=30943822]Ken's WU Juggling Guide[/post] and applying it once you figure out how long each WU will take. Note that the automatic time estimate isn't very good; estimate total time manually from progress and elapsed time.
- Not running a GPU project. They don't all take much CPU time, but they do all take some. Unchecking the two "Use GPU" checkboxes on your PrimeGrid preferences may help you get work faster and more easily.
What won't help (but won't hurt either):
- A large amount of RAM.
- A GPU. Sorry, GPUs just don't have fast enough RAM to matter.
- Any Android devices. (Unless you use them for your own purposes, and thus leave your PC alone to work.)
