[QUOTE=petrw1;300132]Not yet....still nothing below 28M and most at 29M[/QUOTE]

Yeah... That's as expected.

Spidy doesn't have any special privilages from PrimeNet. The queue will get lower exponents as they become available early tomorrow morning (UTC).

Are we slowing?

Or is this just a sign of too much progress (i.e. caught up) and less critical of a need?

We're pretty steady-state at the moment; and have [URL="http://www.gpu72.com/reports/overall/graph/quarter/"]been for the last three months[/URL].

Don't forget that our #2 contributor, Xyzzy, only submits once a week or so. That explains the lower "GHz Days per Day of Work Done" showing on the graph over the last few days.

However, with regards to "caught up", that's definitely the case in the DC range. We are currently over 400 days ahead of that wave. And, while I'm "talking", I had might as well mention that a few days ago the last few DC candidates at 67 bits (in the 36M and 37M ranges) were brought up to 68.

Work saved is dropping as we're doing higher bit levels now. (higher bit levels = more GHz-days needed to yield a factor; work saved = f(factors found, etc) ) To be expected.

Is Xyzzy submitting all results now? (not just factors found)

I thought that might be cause for slowness trend.

Good point. While we're working in the higher ranges, where each factor is worth more using the "GHz Days Saved" metric, we're also effectively only working from 71->72 (or ->73) which takes more work per factor found, as all the "low hanging fruit" has already been harvested at the lower bit levels.

Yes.

[QUOTE]Is Xyzzy submitting all results now?[/QUOTE]Since George tweaked PrimeNet it will now accept 3000+ line uploads.

:whistle:

[QUOTE=Xyzzy;300568]Since George tweaked PrimeNet it will now accept 3000+ line uploads.[/QUOTE]I have noticed this too... I just uploaded 2501 lines myself.
Of course, my 2k5 lines (about 2 weeks work) totaled 368GHz-days... or about 5 [i]nucleon[/i]-hours :flex:

Missing P-1 assignments?
 
Last night I was down to 27 pending P-1 assignments. So I did my usual
weekly grab of 80 exponents (about a week's work). I only got 70
exponents. So I grabbed another ten. 80 exponents, distributed around
my various machines.

Check the P-1 factoring progress report, see that only 77 exponents are
assigned to me. Now, this morning, it's down to 73. That's only 50
exponents assigned. What happened to the other 30 that I see in the
file I downloaded from GPUto72?

Not sure.

Could you please PM me a couple of examples of P-1 assignments which you don't see any more?
