Some records for the week:

Absolute:

12 12 85029720714771 R 52
13 13 85029720714771 R 52

Riesel:

22 41 104169095715013 R 52
54 349 85132812172945 R 52

I got my first E162 very prime series. Rest that now. Will work one core on Riesel E148 this week.

E148 looks more in line now, found a couple of VPS.

Will transfer to E130 as the records there look very weak

Records for this week, all absolute (best of Sierpinskis or Riesels):

73 948 147707435198851 R 52
74 972 147707435198851 R 52
75 1010 147707435198851 R 52

Sorry to be out of touch for a while, I decided to "pull out all stops" and have been using all machines, even my "internet connection" machine, for cranking. I have one Riesel prime generator with 163 primes so far, still testing. I have one top 100 prime (started testing in October) and I have developed a massively-parallel siever which seems to be working fine. Over an exponent range of 10 million it exceeds 10 trillion primes/day. Over smaller ranges it is much faster.

Wow! Seriously impressive! 10 trillion primes = 100 billion plus payams - that's possibly 1/10th of all the work done on this in the last 7 years, and that is all in one day!!

Start posting interesting stuff as you find it.

Which E value(s) are you concentrating on?

Back in the UK now for Xmas, so taking a break from crunching

I should clarify, this was for my [B]siever [/B]program. The sum of the primes generated for the sieving operation = 10 trillion/day on one machine with 6 cores, one "baseline" sieve file is created IN RAM, then 5 parallel cores operate on it.

I am waiting for our dear friend Karbon to get my name correct on his Riesel pages before I submit more results, ditto for Chris Caldwell on the Top 5000 Primes list.

I am only working on the first 3 exponents you had assigned to me, E58, E60, and E66. Was there others you wanted?

Are you familiar with the program called Team Viewer? Perhaps I can let you log in and run some stuff on one of my machines @ 4.8 GHZ or 5.0 GHz, if you would like.

I'm sorry, if I've anything missed, but which post(s) do you refer to? Which pages of mine and which k- and n-values?

I will respond to you privately

Thanks.

This makes no sense. We don't "sum primes" for anything. Perhaps you mean to say that your sieveing rate is P=10T per day on 6 cores. If so, there's no way to know if that is fast with those 6 cores without knowing how many k's are being sieved at once. If it's one k, that's not particularly fast.

Maybe you should try [U]reading the post[/U] instead of splitting hairs over nomenclature.
