BOINC Sieving

[Matt]

The PrimeGrid project is now running a boinc project which includes the PSP project, which also includes our sieving as far as I am aware. This means we effectively have a BOINC client for SOB (sieving) which is pretty awesome if you ask me.

You can see the ranges reserved by PrimeGrid here

That's right. And you an in fact go to www.primegrid.com , get the boinc client, and get crunching. The sieving part is joint sieve for Seventeenorbust, and PrimeSierpinskiProject, so of great overall efficiency.

In something like two weeks, they found more than 1300 factors already, meaning that we eliminate about as many candidates by sieving as by LLR now.

Looking into the 2007 stats ( http://www.henleyclan.co.uk/sobsieve/2007/scores.htm )
you can see that primegrid has already reached place 14 in the yearly stats.
And that after only 2 weeks.

That is not counting the factors which have not reached the "active windows" yet. Which is worth more in points. Once it caught up with the "active window", watch it rocket to the moon.

Make that 5th, and looks like by tomorrow they'll have submitted the largest number of sieved factors for the year.
Sieving has gone mainstream
