[QUOTE=gd_barnes;292080]So are you going to test S998 any further if no AVX version of PFGW/LLR is released? There has been no status update in 8 months.

Are there anymore primes for S383? I can't update the range tested without knowing.[/QUOTE]

Well currently I'm sieving n=100K-1M at around 100T, with a removal rate of about 6564 sec/factor. When PFGW (apparently sometime in the next few weeks) will be realeased, then I'll reevaluate the removal rate and reserve whatever n it fits. So for now, and untill I know more about testing times with PFGW supporting Sandy Bridge and AVX, I'll hold my reservation at n=200K.

Regarding S383, there was no new primes.

To the rest of you, thanks for your recommendations and links, but I have tried some of them and I had more troubles than fun with those versions of LLR and PFGW that other people builded, so I'll wait for Rogue or Jean to come up with something official :smile:

Take care

S386
 
S386 tested n=100K-200K - nothing found

Results emailed - Base released

Reservations
 
Reserving all 1k bases >400<500 to n=500K (Riesel & Sierp)

I will be running these concurrently, so this will take a while.

I'm sure it will. That is an utterly huge amount of work, especially S406. I count 28 conjectures that fit that, although I don't know if some were already reserved by others. I don't know how many cores you have or how fast they are, but if you had 1 core per conjecture, it could take you 3 years to complete.

That's about what I guessed, 3 years. Of course, finding primes will cut into that. I'm putting between 16 -20 cores on it. Q6600's

And I thought I was taking large bites *lol*

When you're done with that you'll be ready to complete R3/S3 to n=100000. :razz:

You will certainly add a few Top 5000 primes during your search and will likely have the top primes found by this project.

I just got tired of doing the 1kers one at a time. If I'm going to spend 3 years doing them one at a time, I may as well just bite the bullet and do 28 at a time. I'm counting on solving 2 or 3 below n=110K.

taking R468 from 25k to 50k

R366 tested n=200k to 250k, no primes. Continuing.

R468 25-50k no new prime
residue attached
will continue to 75k
