[QUOTE=chalsall;576646]A question just hit me... Is the space explored with P+1 different as a function of the B1 and B2 values?[/QUOTE]

Thanks for the edification wrt my first paragraph.

My second question stands. (Please forgive me. I'm a coder / sys-admin. I barely understand half of the maths conversations held around these-here-parts... :smile:)

[QUOTE=chalsall;576661]Thanks for the edification wrt my first paragraph.[/QUOTE]

Sorry... Juggling too many things at the moment...

That was meant to read thanks to James and masser for the knowledge. What you wrote makes sense.

It's kinda cool how fast stuff happens here! :tu:

It might also be a good example to point to demonstrate how deterministic code can quickly enter rarified domains where empirical data and statistics have to be brought to bear to properly understand what's to be expected. A bit like the halting problem.

I'm serious when I say coding up and then running the Mandelbrot set on my C64 is when I became agnostic (from atheist). :chalsall:

When you open the pipe for P+1 auto assignments call me. I will put ~30 cores to it for a week or more.

[QUOTE=kriesel;576626]Or P+1 relevant columns, added to that page, that already has TF and P-1 combined concisely?

+1 :tu:

I tried:
Pplus1=N/A,1,2,1000033,-1,10000000,250000000,2,1000000000,"6000199"

UID: mikr/Nitron, M1000033 has a factor: 6000199 (P+1, B1=10000000)
The programme didn't continue.
What did I do wrong that stage #2 wasn't executing?

Could be a bug. However, I am confused about the bolded parameter: Pplus1=N/A,1,2,1000033,-1,10000000,250000000,2,[B]1000000000[/B],"6000199"

It is supposed to be the depth of TF in bits. The value you've given (1000000000) is way too high. Don't know if that has anything to do with the bug.

How much memory (RAM) does your machine have?

The worktodo line below requires 3.6 Gb of RAM on my machine; I would guess that a larger B1 would imply a larger B2 and require more RAM.

[Work thread Apr 24 08:50] M1000033 stage 2 is 1.53% complete. Time: 1.675 sec.[/CODE]

[QUOTE=axn;576736]Could be a bug. However, I am confused about the bolded parameter: Pplus1=N/A,1,2,1000033,-1,10000000,250000000,2,[B]1000000000[/B],"6000199"

It is supposed to be the depth of TF in bits. The value you've given (1000000000) is way too high. Don't know if that has anything to do with the bug.[/QUOTE]

Clearly I misunderstood the parameter you indicated. I thought it was about the B2 increase.
