Jumping to 1 million digit LLR tests

paulunderwood · 2006-02-10, 15:20

In about month from now Thomas and I will have finished the sieving for 321search to the optimal level of division of 236 trillion. This leave only LLR work from "n" = 2.5-5 million -- That's 0.75-1.5 million digits.

The purpose of this poll is to guage interest in jumping from our current testing window to tests that have at least 1 million decimal digits.

Tests at 1 million digits only takes half as long as they currently do. So an average 321-LLR file on a super-duper P4 will increase from 5 days to 8 days. (This will be going upto 6 days soon anyway)

The primes are rarer at 1 million digits but with sufficient crunching and a little bit of luck we could find something huge in a reasonable amount of time.

I guess we'll continue as we are...

I haven't contributed yet, so my opinion doesn't much matter...
but you could post files from both, let people choose on their own. 15k has done this on a project or two. Most choose the higher range, when presented with the choice, but some like to work on lowest available.

Due to the administrive overhead of running two lists, until "the pack" reaches 1 million digits tests around August 2007, I suggest anyone who is interested in testing for one million digit prime tests now emails/pm me.
