P=8800G10000G is complete. no primes found
many possible primes were eliminated though!

I was wondering if anyone would catch that. Funny thing...I actually started to type that out of habit and then said what the heck am I doing? Then I just went with it. lol If anyone finds a prime n>100K while sieving, let me know. We'll award you a gold medal! I say n>100K because srsieve will actually "announce" small primes on the screen if you sieve starting at an extremely low nvalue like n=1.

Rereserving Nugget's range of P=8200G8600G. We can't wait any longer for it. Perhaps he'll show up midway through and I'll be able to stop. I think a quad will slay it fast enough. If not, I'll put 2 on it.

I assume this is just because it sieves past the square root of the number without finding anything, right? How long would it take (I know it'll be way, way past the realm of practicality, and probably possibility as well) to confirm via sieving only, with sr*sieve or NewPGen or something, (maybe include Prime95?) that a number with n>100K is prime?

it doesnt do square root for some reason although it would be very nice if it did

Henry is correct. For example, if you are sieving and just happen to have k*2^n1 calculate to a value of 101; srsieve will not display it as prime until it has sieved to P=101. This is OK as far as I'm concerned because srsieve will actually correctly leave the pair in the sieve. sr1sieve and sr2sieve either barf at such a low pair or improperly remove them. NewPGen is extremely bad about that; it actually removes them from the sieve without saying a word. For that reason, I never use NewPGen anymore except for twinprime sieving at higher nranges. Also, it's far too slow. Gary
