The Riesel Problem LLR race will not be seen this month, but will be rescheduled for October. Instead, please stay tuned for the following special race announcement.
PrimeGrid has a new project! Well, not quite yet, but they will by the 14th. And on the 15th we'll start racing with it. I sure hope they've thought this through!
I think they have, because it's another LLR project. But since it is so new, I don't know how long each work unit will take. Here's what I do know:
The race is three days, from June 15 to June 18, starting and ending at 18:00 UTC.
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 don't know that for sure either!)
What I do know is that I wish luck to all!

The race is three days, from June 15 to June 18, starting and ending at 18:00 UTC.
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 "SR5 (LLR)" (Or maybe "Sierpinski/Riesel base 5"?) selected in the Projects section.
- Patience! I honestly don't know how long these WUs will take, but they could be long.
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. Or maybe not - these might be short WUs.)
- Having hyper-threading off on i3/5/7s is said to help.
- Following [post=30943822]Ken's WU Juggling Guide[/post] toward the end might help too.
What won't help (but won't hurt either):
- A large amount of RAM.
- Any video cards.
