Welcome to the PrimeGrid Perseid Shower challenge. This is the only sieve challenge - and only sieve project left - that can't using a graphics card.
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 12 August 2013 at 18:00 UTC and runs for only two days. Only work downloaded and uploaded during the challenge will be counted. Should you not be able to be in front of one or more computers at the start time, either set their queue level to zero (0) days or try one of the scheduled start methods from [thread=2051485]the strategy thread[/thread]. 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.
Welcome and good luck to all! :thumbsup:
What you need:
- One or more fast x86 processors. (Even slow ones will do!)
- Windows, Linux, or MacOS 10.4+ Edit: or Android!
- BOINC, attached to PrimeGrid (http://www.primegrid.com/). (Download the official BOINC client for Android if you want to use your mobile device.)
- Your PrimeGrid Preferences with only "The Riesel Problem (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.
- Enabling hyper-threading may be helpful for this project only.
- Downloading a few WUs early. This project has a large (35MB) one-time sieve file to download.
- Reading [post=30943822]Ken's WU Juggling Guide[/post] and applying it once you figure out how long each WU will take.
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.
