What for checkpointing, it is problematic to implement checkpoints in this experiment, because the sub-trees on which we perform exhaustive search are very different in sizes. If we do a checkpoint at higher tiers of the tree, it is very likely that 9 of 10 sub-trees will be processed very fast, and the 10th will take several hours, so no sense in a checkpoint. If we go into the recursion 1-2 tiers deeper, the check for need of a checkpoint will be performed too often and increase the whole runtime of a task several-fold.

How about using a fixed time interval for a checkpoint trigger with the checkpoint data pointing to the start of whatever calculaton that is happing at that moment?

Yes. But time check must be placed in code. If the check placed on one tier higher, it won't make sense, if placed on one tier lower - affect the performance.

Hi folks!

Some news: current search will be extended with new set of workunits.

Great!

By the way, what achievement is necessary to be awarded one of the month badges like the Oriolus "Findings at the November 2020 joint search..." And shouldn't it read 2021 instead of 2020?

Saludos...

Hello Drago75!

We will make another badge for November'2021!

Hi,

How can I detect a finding?
I've run some WU of the new search. Scanning the result files show two different variants:

files with a zero in the second line

0123456789AB123498B5A0......
0

and files with a non zero number in the second line

0123456789AB123498B5A0675.....
26700

Is this a notice of a finding, if not, how then looks a result file with a finding?

Jürgen

Hi! Yes, a non-zero number indicates there have been found ODLSs in this task.

Dear participants, we are summing up the results of November.

The badge of November'2021 is Middle spotted woodpecker - a middle sized bird lives in forests of France, central and eastern Europe. (Image source can be found on Birds of the Kursk region page).



Our warm congratulations to participants whose computers return results with a non-zero number of ODLS pairs:

Thank you for participation and donation of CPU time!

That's nice.
Are the individual ODLS findings going to be added to the user accounts as before?

Hello Michael!

Are the individual ODLS findings going to be added to the user accounts as before?

It's impossible. The number of found orthogonal squares for some workuinits is counts of tens thousands.

Hello folks! Due to exhausting of first tasks set we prepare the next set and correct counters used for display of research progress.

Thank you for participation!

...ok, so juast as in Amicable Numbers project.

Excited about getting a new RakeSearch badge after such a long time!

Welcome back, Steve! :)

Hello!
May I know what the project is looking for: transversals, D-transversals or ODLS of order 12?

The first challenge is to beat the current record on the number of transversals for DLSs of order 12. We already have tasks for the next 2 months, and there will be more.

0123456789AB123498B5A0675.....
26700

What does the number 26700 mean?

Good day!

May I know what the project is looking for: transversals, D-transversals or ODLS of order 12?

We hope that details will be published in future publications and we will be able to simply refer to them.

What does the number 26700 mean?

It's a raw number - item for post-processing of project results.

Hello!
There was another answer to this example

0123456789AB123498B5A0675.....
26700

Hi! Yes, a non-zero number indicates there have been found ODLSs in this task.

From this answer, I understand that the number 26700 here means the number of ODLSs.

Dear participants, we append info tasks queue bunch of tasks with short deadline, equals 1 day. We expect these tasks to be fully sent out in 12 hours. Subsequent tasks will have the usual 7-day deadline. Thank you for participation and donation of CPU time!

---

In the next few hours, the project will switch to a new bunch of tasks. We adjusted the progress counter.
Thank you for participation!

I think it would be good to put links to the results published as separate news here:
Square # 4 (1st square at this moment by number of ODLS)
Square # 5 (3rd square at this moment).

Thank you!

Hello folks! We switched to next set of workunits - for square # 7.
