Of course, it's not as easy as just attaching to a BOINC project! This is old-skool manual distributed computing. First, you need one or more fast machines, preferably quad-cores. Edit: A 64-bit OS is better, but John says 32-bit is OK too. They also need at least 2GB of RAM (unless you want to work even harder at this.)
Next, go to the PrimeGrid message board and PM either Project Scientist John or Lennart. Tell them you want to join the PPSE (Proth Prime Search Extended) sieve. They'll send you a link to another board where you sign up, download the app and the 1GB+ data file, sign up for a range, and start crunching!
If you're wondering how all this came about...well, it's sort of my fault. I joined the project less than a week ago, but once I started I noticed how the work was similar to the Twin Prime Search Sieve I'd worked on a couple of months back. So I tried reworking that application for this sieve (yes, that is the app, on my site), and it turned out to run six times as fast as what they'd been using! Well, this threw the manual BOINC credit they were giving for the sieve completely out of whack. Initially I thought they'd renormalize it quickly, but they began by not changing it at all, and (Edit
now for the next 20 trillion P's they're ratcheting it down to 4x normal.
So get your work while it's hot - this is a limited-time offer!
