[QUOTE]And why do some folk (no names/no packdrill) hoard 6000 TF assignments at once, when those assignments could be distributed?[/QUOTE]No network access? Limited access to the hardware? A hoarding compulsion?

[QUOTE=davieddy;282537]Would it not benefit GIMPS if a few more of the LLs currently being dished out were TFed adequately?

Broken Record

PS Why should the "expiry time" for TF assignments be anywhere near to that for a LL?
And why do some folk (no names/no packdrill) hoard 6000 TF assignments at once, when those assignments could be distributed?[/QUOTE]

Silly, us GPU to 72'ers are still working on eliminating exponents available for assignment only TF'ed to 70 bits..we'll get there....

And 6000 assignments, while a lot of work on my machine, is something like only 3 weeks work for Xyzzy!

My eyes are dim, I cannot see...
 
[QUOTE=Prime95;282365]I have 5 more exponents that need more TF:


72000209
72000283
72000343
72000449
72000479

They have already been TF'ed to 2^70 (and P-1'ed). They should be taken to 2^73 or 2^74 before I feed them to CudaLucas.

Any volunteers? Thanks.[/QUOTE]
I have not brought my specs with me etc....
Although the three zeros make the order of magnitude fairly easy to diagnose in this case, there is a fairly standard convention of inserting a comma every three digits which can help on occasions. Especially when 99.99% of the "recently cleared" consists of factors of Nxx,xxx,xxx of interest to neither man nor beast.

These have been turned in to PrimeNet.[/QUOTE]What the hell :P

[code]no factor for M72000449 from 2^70 to 2^74 [mfaktc 0.17 barrett79_mul32][/code]
Also consider adding these 5 exponents to LaurV's thread listing exponents tested once with CUDALucas.

[QUOTE=nucleon;282516]hhehe I should of checked how much work that was.

4 of them done in <3days
the one done in <5days

-- Craig[/QUOTE]

Yikes. For me each exponent takes more than three days. Anybody else want to grab two of mine? Or one?
Also:
[code]no factor for M72000343 from 2^70 to 2^74 [mfaktc 0.17 barrett79_mul32]

[QUOTE=Dubslow;282618]Yikes. For me each exponent takes more than three days. Anybody else want to grab two of mine?[/quote]I'll take two... which are they?

Dubslow 2011-12-17 19:34

You sure? They'll take forever unless you have a 580 or something.


[code]Factor=332250257,74,79
Factor=332250461,74,79[/code]

James Heinrich 2011-12-17 22:07

[QUOTE=Dubslow;282621]You sure? They'll take forever unless you have a 580 or something.[/QUOTE]A 570 will have to do. :smile:
ETA is 2h06m for 74-75, so:
75: 2
76: 2+4
77: 2+4+8
78: 2+4+8+16
79: 2+4+8+16+32
: ETA mid-Tuesday (~68'ish hours from now)
Assuming no factors found, of course!

Dubslow 2011-12-17 22:10

Well for me it's like 72-75 so that's not much of an improvement...

James Heinrich 2011-12-20 23:01
