[QUOTE=tha;369182]I wonder what the effect of tablets replacing pc's will be. For sure pc's won't be upgraded as often. I have no legitimate reason to upgrade my 2007 era pc. Plenty of illegitimate reasons though.[/QUOTE]
There are plenty of office desk PC's that will remain as such. They will also get 'life-cycle' replacements. A tablet can't touch a wide screen monitor with a real keyboard attached.

[QUOTE=Uncwilly;369171]Today, for the first time (in the modern era), the projected end of the 79.3M range is in 2017 or earlier.
The current projection is 12/30/17.
This is based upon the changes in the P90 years remaining.
It will move downward as we move along It may actually come before the end of 2015.[/QUOTE]
When is the projected end of the 100M range?

[QUOTE=c10ck3r;369215]When is the projected end of the 100M range?[/QUOTE]I do not have data to do that projection. I am using the change in P90 years as posted in the "classic" report.

Just in time to celebrate with a green beer:

Your cat prevents me.

What? Is GIMPS not a legitimate enough reason? :shock:
:lol:

[QUOTE=kracker;369230]Your cat prevents me.[/QUOTE]

Fortunately, you are right. My cat insisted I celebrate with a traditional stout. And a few fiddle tunes, but the cat was not too happy about that.

I don't remember the thread, but there was recent discussion of finding multiple factors. Over about nine hours today, while I was at work, my GTX 570 found three. This was in addition to 21 No Factor results for the combined output of the 570 and 580.

And then there were none.....
 

[QUOTE=petrw1;368008]1277 to 61 bits. 1 to go. Early April or so.[/QUOTE]

Tomorrow there should be no 60 column on GPU72

[QUOTE=petrw1;370285]Tomorrow there should be no 60 column on GPU72[/QUOTE]

Column or row? And, are you planning to wipe out 2048 73-74 bit exponents overnight?

Just got done. No more exponents trial factored to less than 61 bits.
Good job, petrw1, the "tail" in the table got shorter.
Tackling 61 bits will be way harder a job, though...
