It's David, actually.

But it says to just call him Henry!

I mean, you could call me Mike if you wished, but folks would get confused.

That is exactly right![B] It[/B]. (Because it is not the users who write those [STRIKE]cursed[/STRIKE] cursive lines.)

As the old Soviet joke goes, "In [STRIKE]the USSR[/STRIKE] this forum, all is created for the man and all is for the love of man and for the sake of man ... And I [B]saw[/B] that man!!" :rolleyes:

It is all tests by me since tests were removed last time.
I am pretty certain 99+% of them are perfectly good. In fact I suspect I may be stable apart from when using hardware decoding(very rare). I have run several days stress testing and a successful gimps double check.
I would imagine it is more stable than some who have submitted pairs during races with distributed computing routes(overclocked pcs etc).
How accurate do we need?
I would be very interested in knowing the results of a doublecheck of the results returned by this pc.

[url=http://primes.utm.edu/primes/page.php?id=123285]617*2^1451432-1 is prime![/url]

The Prime Pages site warned me when I submitted that at the current rate primes are being added, this will be pushed off the list in about 40-50 or so weeks. Has anyone run the numbers to make sure we're staying ahead of that curve? (Ports 2000 and 9000 are tracking pretty close in [i]n[/i] right now and have similar resources on them, so they'll both be in the same boat.)

If need be, I can shift some resources over from CRUS 1400 to give one or both ports a boost. Right now I have 1 Haswell on 2000, and 4 more on 1400 (+2 Nehalems, but they don't count for much these days so I wouldn't bother moving them).

At position 2500 that seems unlikely. The calculation is likely done based on the number of digits in the 5000th prime. Since there are so many n=1290000 primes that it skews the calculation.

I expect it to be longer than that.

On the "[URL="http://www.noprimeleftbehind.net/stats/index.php?content=drive_progress"]Drive Progress[/URL]" chart, the red line shows the lower limit of the top 5000.
It is is updated daily based on an update from the top 5000 page.
It is actually a complex curve but it looks fairly straight on this scale.

Also on the "[URL="http://www.noprimeleftbehind.net/stats/index.php?content=prime_list"]Prime List[/URL]" page you will see the second line of the description currently says
"Last updated minimum size for the Top5000 database is 388342 digits."

This number of digits of the smallest prime in the top 5000 is updated daily at the same time as the red line on the chart.

Not so many anymore. Used to be 2900, now less than 200 and shrinking, and in a couple of months they will be all gone from top5k, except those that were collected into AP[SUB]3[/SUB]s, the SG pair and the twin pair. I wonder if they will continue running them, just like they still run GFN"15"s.
