Hey, y'all, it's almost time for the Low Country Festivities!
Um, better make that the "Low Country" Festivities!
"The Standard Australian Square Dance"? Let's just call it a PrimeGrid race, OK?
Welcome to the second-most grueling PrimeGrid challenge of the year. Your mission, should you choose to accept it, is to complete as many Woodall LLR tests as you can, as quickly and correctly as you can. Because these work units take longer than most, you will have a full eight days, from April 29 to May 7, both at 18:00 UTC, to work on them.
What you need:
What might help:
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 the challenge strategy thread for ways to start and finish on time. (I think my Bash script for Linux is up-to-date, but I wouldn't guarantee it.)
Good luck to all!

Welcome to the second-most grueling PrimeGrid challenge of the year. Your mission, should you choose to accept it, is to complete as many Woodall LLR tests as you can, as quickly and correctly as you can. Because these work units take longer than most, you will have a full eight days, from April 29 to May 7, both at 18:00 UTC, to work on them.
What you need:
- One or more fast x86 processors. See below for the best kinds.
- All of those processors running stably. One good way to check that is to run PPS or SGS LLR for a few days. (Although Prime95 may be a more reliable test.) 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 only "Woodall Prime Search (LLR)" selected in the Projects section.
- Patience! These are long WUs. (Not as long as Seventeen or Bust, but each will probably take more than one day.)
What might help:
- AVX on Intel i3/5/7 processors. It nearly doubles your speed.
- A 64-bit OS. (I think it helps a little with the latest version.)
- Fast RAM. (DDR3-2133 may be 10-15% faster than DDR3-1600.)
- Having hyper-threading off on i3/5/7s is said to help.
- Following [post=30943822]Ken's WU Juggling Guide[/post] toward the end would help too.
What won't help (but won't hurt either):
- A large amount of RAM.
- Any video cards.
