[QUOTE=ET_;392956]a cold room in Canada means -20°C... :razz:[/QUOTE]

I've had it as cold as +5°C when I left the window open too far.
I try to keep it around +15 ... that seems cold enough to get the 515GD's

And that's the way we like it!

[QUOTE=petrw1;392877]Never mind, I can look it up ... VERY FEW exponents in the 6x - 7xM range are factored to the optimal 75 bits.[/QUOTE]

Actually, [URL="https://www.gpu72.com/reports/current_level/"]this is a better report[/URL], in that it shows the bit level for each class of candidate; LL and DC.

[QUOTE=Xyzzy;392863]What is the optimal LLTF strategy?[/QUOTE]

Sorry; missed this... "Let GPU72 Decide" or "What Makes Sense". I try to be as optimal as I can for the project on the whole, and when the transition to Primenet is completed assignments will be even more optimal as the decisions made will be based on Primenet "insider" knowledge I don't have access to.

[QUOTE=chalsall;392973]Sorry; missed this... "Let GPU72 Decide" or "What Makes Sense".[/QUOTE]The last time we checked those options returned different results. One was TF to 75 and the other was TF to 74. We took the 74 work because we are not sure what work is being released right now.

Sunday Night Wrapup #7 - January 25, 2015
 
59,205 DCTF in the last week. (See note at the end)
66 different contibutors
116 Factors found
6,995 P1/LL/DC work saved

22 contributors currently have assignments
1,977 Assignments out. (About half of last last week)

710.0797 estimated days to completion
January 5, 2017

A good part of the week was spent by some of us refactoring some suspect work .... and finding dozens missed factors ... which will eliminate those from the list that needs more TF, P-1, LL and DC.

I'm being lame and I'm going to do a bunch of LLTF for the next week.

Me too....maybe a short reprieve for DCTF.

Seems LLTF needs us more

Seems "The Mawn" as well is moving there.

Going to restart my laptop again soon. Pity that it does only 120Ghz/day or so, iirc.
I'll probably have to empty the worktodo file, as those exponents are obsolete.

Sunday Night Wrapup #8 - February 1, 2015
 
33,089 DCTF in the last week. ... less than 30% of update #1
63 different contributors
55 Factors found
3,284 P1/LL/DC work saved

16 contributors currently have assignments
973 Assignments out. (11% of update #1)

926.4635 estimated days to completion (almost 4 times longer than update #1)
August 16, 2017

Because of the need to help out more in LLTF many of us have moved our work there.
Until (if ever) LLTF is far enough ahead that we can refocus here I will reduce to monthly updates here.

petrw1 2015-02-02 21:50

Correct me if I'm wrong but .... I don' think this is the end of it
 
Currently GPU72 lists exponents below 60M that need DCTF (that is LL done DC NOT done and TF level deemed too low).

Are there not, though exponents above 60M that have LL but NOT DC that also should be TF'd higher before DC is done?
