[QUOTE=retina;367705]Countdown to proving only 44 Mersenne Primes less than 10M digits: ?

The query below is limited to 1000 results:
[url]http://mersenne.org/assignments/default.php?exp_lo=1&exp_hi=33219278&execm=1&exfirst=1&exp1=1&extf=1[/url]

Is there a way to get just the count of exponents within a range without returning each individual status?[/QUOTE]

Not exactly, AFAIK, but you can get the counts for 30M-33M (<30M is fully proven) from [URL="http://www.mersenne.org/primenet/"]the summary page[/URL]:
[CODE]
----------=-----=-- | -----=-----=-----=-----=----- | -----=-----=-----=----- | -----=-----=-----=----- |
Exponent Range | Composite | Status Unproven | Assigned | Available |
Start Count P | F LL-D | LL LLERR NO-LL | TF P-1 LL LL-D | TF P-1 LL LL-D |
----------=-----=-- | -----=-----=-----=-----=----- | -----=-----=-----=----- | -----=-----=-----=----- |
30000000 58120 1 | 36902 21098 119 | 119 | |
31000000 57836 | 36761 18613 2462 | 2029 | 433 |
32000000 57852 1 | 36913 9203 11735 | 8567 | 3167 |
[/CODE]
Then checking 1000 results (starting with your link) at a time for 33M to 33.2M, I find 3590 in that range, for a total of 119+2462+11735+3590=17,906 DCs remaining.

Then checking 1000 results (starting with your link) at a time for 33M to 33.2M, I find 3590 in that range, for a total of 119+2462+11735+3590=17,906 DCs remaining.[/QUOTE]Okay, thanks.

This query returns all results but contains duplicates:
[url]http://www.mersenne.org/report_LL/default.php?exp_lo=28873849&exp_hi=33219278&exp_date=&user_only=0&user_id=&exdchk=1&exbad=1&exfactor=1&txt=1&dispdate=1[/url]

After removing duplicates I got 17999. Where are the extra 93?

Using the same report_LL page and duplicate removal for each individual range I get these counts:
30M=118 - discrepancy of -1
31M=2459 - discrepancy of -3

There appears to be no obvious way to get reliable numbers. And each individual query suffers from the problem of not being atomic with figures potentially changing between each access.

I guess it will have to do until the number drops below 1000 and a single query can return the entire range.

The discrepancies of 1 and 3 per million can probably be explained by recent completions (the status I quoted is updated every hour, I think). Stats are now (2014-02-24 16:01 UTC):

32000000 57852 1 | 36913 9211 11727 | 8563 | 3163 |[/CODE]
I think that looking at assignments (as I was, based on your first post) isn't the right way to go, because of the fact that not all 'status unproven' are assigned, starting in the 31M block (as the stats above show). So, based on using your report_LL query for 33M-33.2M and finding 3693 distinct in that range, I think the actual figure as of ~16:01 UTC is 118+2459+11727+3693=17,997

Of course not. GPUs should only be doing TF'ing at the moment, and for the foreseeable future.

LaurV et al's point, however, is valid. Under the new assignment rules proving M(32582657) is the 44th Mersenne Prime will very likely be accomplished this year (mostly using CPUs).

I can do [I]much[/I] better than 2 per per day if I really wanted to/stopped messing around.

:razz:

My poor minions.

Nope. All assignments prior to March 1, 2014 are grandfathered -- given a full year to complete. I'm guessing we won't prove M#44 until June 2015.

What about poaching? :wink:

[QUOTE=chalsall;367738]What about poaching? :wink:[/QUOTE]

The recent wave of poaching was after a long time of 'residue' building up. I think we will see a low level again for lack of residue. By the time new residue will be build up the new rules will be in effect.

It seems the report_LL is currently the closest approximation to get the value.
