Resuming L-L with a clean hard drive

2004-12-31, 23:51

I was peacably testing 2070457. According the assignment file, Gimps checked my progress about 4:10 yesterday morning and found I was at iteration 2 million +. When I came to the computer after breakfast, my hard drive was dead (I trust entirely coincidentally!). Anyway I have a new hard drive installed.
How do resume testing my number, preferably not at the beginning?
Thanks!

I hope you have a backup!

This is one reason I use "InterimFiles" every 1e6 iterations... I then back up the interim files periodically...

Quote:

You can have the program generate save files every n iterations. The files will have a .XXX extension where XXX equals the current iteration divided by n. In prime.ini enter:

InterimFiles=n

If you have a backup there will be a regular save file and a backup save file as well...

Worst case you can restart your work by recreating the worktodo.ini file...

Assuming this is you:

Code:

27070457     68   2056703    11.3  37.2  86.2  30-Dec-04 04:48  20-Dec-04 17:22  danjmi         CA3C1D458

Then (I think!) you want this in your worktodo.ini file:

Code:

Test=27070457,68,0

Mmm, the boundary between 67 & 68 is 28130000, so the line in your worktodo.ini should be

Code:

Test=27070457,67,0

Not necessarly... The exponent might have been factored up to 2^68, therefore it's better to stick to what Primenet is telling us, which is 68.

Unfortunately Primenet is misleading us. The user report or status.txt "fact bits" is one higher than the TF level if a p-1 test has been done. I'm pretty sure I read some post saying that it actually adds 0.5 internally, and then the report rounds up... Anyway, for the machine I'm on now, the worktodo.ini has

Test=17813597,65,1

but my user report has

17813597 66 8958364 67.9 12.0 72.0 29-Dec-04 04:27 22-Oct-04 06:14 new

Also, the latest nofactor file has no 27M exponents TF'd above 2^67, although it's not as current as a primenet report.

It won't affect anything anyway, since the p-1 step has been done.

So the correct worktodo entry is:
Test=27070457,67,1
