P=75G-150G complete; factors sent in an Email to Anon.

Now working on P=500G-750G; ETA is mid-morning 3/31.

New sieve file is now available, with all factors removed up to p=500G.

You can get it here; I also updated the link in the first post of this thread.

I didn't get the factors for 750G-1000G yet, and it's over 6 hours later. Did you forget to send them by any chance?

Hi all,

Since two primes have just been found in the team drive for Sierp. base 6, I've removed the respective k's from the sieve file. You can download the updated sieve file here; I also updated the first post of this thread.

KriZp · 2008-03-31, 10:04

yes I did: I'll send them right away

Reserving 1500G-1750G.

Anon, I think I'll use KriZp's P-rate/sec and your LLR speed here for optimum sieve depth calculations.

Can you LLR a candidate at n=135K and at n=170K sometime today? We can then decide whether we want to break off n=100K-150K or n=100K-200K.

KriZp, what is your P-rate/sec at P=1200G?

Using the fastest siever and a fast LLRer will be more accurate. The optimum depth will be deeper than calculating it using a slower machine but we'll get there faster so the total time spent sieving should be only slightly longer but will save much more time LLRing.

p=1320074545843, 1729588 p/sec, 552 factors, 40.0% done, 125 sec/factor

with the new sieve-file.
When I shut it down in order to change to the new sievefile it reported this:
sr2sieve 1.7.9 stopped: at p=1288626833551 because SIGINT was received.
Found factors for 420 terms in 52927.273 sec. (expected about 432.00)=126 sec/factor
and now
sr2sieve 1.7.9 stopped: at p=1320447776779 because SIGINT was received.
Found factors for 552 terms in 71263.464 sec. (expected about 560.65)=129.1 sec/factor
