Welcome to the last chance to find primes in a race this year. It's the Leonids Challenge! Your mission, is to complete as many 321 Prime Search LLR tests as you can, as quickly and correctly as you can. You will have five days, from November 18-23, to work on them.
What you need:
What won't help (but won't hurt either):
What would help, but isn't absolutely necessary:
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.
Good luck to all!
P.S. Sorry I'm getting later and later with these. :$
What you need:
- One or more fast x86 processors. (Even slow ones could probably do some work!)
- All of those processors running stably. One good way to check that is to run PPS or SGS LLR for a few days. If those make your processor too hot, try TRP LLR. If you get any errors, your processor probably isn't stable at your current clock/voltage.
- Windows, Linux, or MacOS 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 won't help (but won't hurt either):
- A 64-bit OS. (But if it's Linux, type "sudo apt-get install ia32-libs".)
- A large amount of RAM.
- A GPU. Sorry, still not working. I hit a server misconfiguration, and another tester has crashes.
What would help, but isn't absolutely necessary:
- 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.
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.
Good luck to all!
