Here is a status report for the range from 332192831 to 332399999:

[code]Date of data 6/20/2011
Average bit depth for first 100 expos 78.31
Average bit depth for first 1000 expos 76.87
100th active expo (no factor found) 332198357
1000th active expo (no factor found) 332245931
Unitless total effort number 157,016,576
Number of first 100 expos to 2^76 93
Number left in range 4255

Estimated expos in range to be removed 465
(by taking all expos to 2^82)[/code]
[code]Bit # at bit level
70 407
71 1617
72 618
73 220
74 133
75 211
76 358
77 258
78 10
79 398
80 23
81 2
P-1 111 ≈9,700,000 effort[/code]
~2,200,000 effort equivalent in factors found by TF.
The 332,000,000 range now has 57.31% of the exponents factored out.
Fancy picture attached.

I'm getting 75/76 bit TF assignments from the server "manual assignments page" in this range, so I assume that there's been a lot more TF since your previous post on June 21...unfortuneately, that means it will be 35 days on average for me to find a factor as the assignments take my GT440 11 hours apiece.

Actually the curve for the effort has flattened some.
Here is what the exponent statuses look like.

Christenson 2011-07-17 14:17

I'll keep doing the half-dozen 75 to 76 bit assignments I have over the next week or two...but how to get the lower bit levels? (it also wasn't clear exactly what the X axis was, I assume it was the nth unfactored exponent over the minimum 100M digit exponent. I just love Microsoft Excel graphics :smile: :batalov::windmill:

[QUOTE=Uncwilly;266686]Actually the curve for the effort has flattened some.[/QUOTE]

Some weeks ago I've switched from 100M digit TF to "regular" TF. :smile:
I'm not sure how big the impact is.

[QUOTE=Christenson;266688]but how to get the lower bit levels?[/quote]Try using the self assigning strategy listed here: [url]http://mersenneforum.org/showthread.php?t=11308[/url].

Here is a link that gets you a bunch of the exponents below 72 bits, use and adjust as desired.

Note that "Exclude currently assigned exponents" is set (this is a must) and that I limited the class to 332299999.

Thanks...got 5 on my worktodo list...don't have time for more cut and paste tonight....

Today all the active exponents in the 332192831 to 332399999 range have been Trial Factored to 71 bits.

Now to start taking them all to 72. :smile:

So noted. I currently have 2 CPU's (single core HT) taking expos to 73 and 1 (dual core) taking expos to 74.

I continue to watch for exponents early in this range showing up as available. I snag them and move them to the head of the queue (as appropriate).
