Welcome to the PrimeGrid Ides of March challenge. It's a short challenge, but beware complacency - I believe this is the most important challenge of the year!
What you need:
What would help, but isn't absolutely necessary:
What won't help (but won't hurt either):
If you're running a 32-bit OS on a 64-bit processor, there are three ways you can run a 64-bit OS for this challenge.
This challenge starts on the Ides of March, March 15, and runs for only 24 hours. Should you not be able to be in front of one or more computers at that time, just set their queue level to zero (0) days. Network connection time options may also be useful - though they depend on your computer's clock being correct, so set the start time a few minutes late.
If you can be in front of your computer part of that time, you can increase the queue level once the race starts, but if you cannot flush your results at the end, please make sure that once your queue level is set to zero days, your queue will run out of work before the end of the race.
The project for this challenge is the Prime Sierpinski Project/Seventeen or Bust sieve. This is the same kind of race we did in November of last year. This application sieves (looks for prime factors more quickly than a standard LLR test can find them) for both the Seventeen or Bust project and for its sister search, the Prime Sierpinski Problem. (The Seventeen or Bust client only performs LLR tests; by participating in this challenge you'll help avoid pointless LLR tests over there, too.)
I'm posting this a little early to give people a place to talk about this specific race, outside the strategy thread.
Welcome and good luck to all!
What you need:
- One or more fast x86 processors. (Even slow ones will do!)
- Windows, Linux, or MacOS 10.4+.
- BOINC, attached to PrimeGrid (http://www.primegrid.com/).
- Your PrimeGrid Preferences with only "PSP/SoB (Sieve)" selected in the Projects section.
What would help, but isn't absolutely necessary:
- A 64-bit OS on a 64-bit processor will run 70% faster than a 32-bit OS.
What won't help (but won't hurt either):
- A large amount of RAM.
- Any video cards.
If you're running a 32-bit OS on a 64-bit processor, there are three ways you can run a 64-bit OS for this challenge.
- Install a 64-bit OS as your primary OS.
- Install a 64-bit OS as a secondary OS. Wubi is the easiest way to install 64-bit Ubuntu Linux alongside 32-bit Windows.
- Install a 64-bit OS on a virtual machine in VMWare. This may not work, depending on your processor, and even if it does work it may be slower than the other two methods. However, it's less intrusive than the other two methods.
