PSP found prime for k = 241489

[Mystwalker]

Good news from the Prime Sierpinski Search:

241489*2^1365062+1 is prime! (http://www.mersenneforum.org/showthread.php?p=48634)

It is the 23th biggest prime found so far. Now, only 14 k's are left for PSP alone (plus the 5 prime k's of SoB).

Is it allowed to say that currently, only 10 people do work? :p

Congratulations.. :thumbs:

GOOD JOB GUYS!!!!

Hopefully you can knock a few more out soon... but

You may consider doing some calculations about where your next primes are expected etc, and try to bring up that 60T sieve level. It will definetly pay off to bring it up to a few 100T sooner rather than later... your efforts will be re-paid several times over.

All in all good work, and how many of our k's are also psp's smaller k's? All of them?

Easier said than done. :(
I already devote my complete processing power (which is mostly ~25 p3-800 almost 24/7) to sieving. Only that way, we are already at 67T...

Let's look what the new sieving client can do once it is ready.

:whip: Join the club, thankfully we are already at 600T+ and have a few dedicated sievers with some fairly serious firepower. But when you compare that power to the porject as a whole :help:

Mystwalker has made significant contribution to where we're now, both in terms of dedicated firepower and ideas...

38.8T of sieving might look as if only 7% (still, WOW!) of 543.3T overall, but a lot of that was done when the clients were relatively crawling to what we have right now. So, in terms of computing power, it's much more.
