Project Update

[jmblazek]

It's been a while since any news has been posted about PrimeGrid so I thought I'd provide an update.

The prime projects at PrimeGrid continue to grow. Currently the following are offered:

LLR Projects (primality testing)

• 321 Prime Search (BOINC)
• Cullen Prime Search (BOINC)
• Generalized Cullen/Woodall Prime Search (PG LLRNet)
• Prime Sierpinski Project (BOINC, LLRNet*, Manual*)
• Proth Prime Search (BOINC)
• Sophie Germain Prime Search (PG LLRNet)
• Twin Prime Search (BOINC)

Sieve Projects (finding factors)

• 321 Sieve (Manual)
• Cullen/Woodall Sieve (BOINC, Manual)
• Generalized Cullen/Woodall Sieve (Manual)
• Prime Sierpinski Project Sieve (BOINC, Manual*)
• Proth Sieve (BOINC, Manual)
• Twin Prime Sieve (Manual**)

* offered through the Prime Sierpinski Project in the Mersenne Forum
** offered through the Twin Prime Search in the Mersenne Forum

As you can see, there's a wide variety of work to do from BOINC to LLRNet to Manual. There are applications for 32 bit and 64 bit Linux and Windows...with MacIntel hopefully by the end of the year. WU's range from less than a minute to more than 48 hours.

Please visit PrimeGrid to see if there's any project that suits your interests. Also, with so many prime searches underway, there's always a need for more sievers. The top three priorities are currently:

1. PPS Sieve (p=68T) - goal, to reach a sieve depth of 500T initially and 850T long term
2. 321 Sieve (p=55T) - goal, to reach a sieve depth of 850T initially and ??? long term
3. PSP Sieve (p=9.4P) - goal, to reach p=10P before 13 October 2008 (1 year anniversary)

I hope to post back soon with a link to FULL project descriptions.
