Dear participants, yesterday, processing of the square # 8 is fully completed!
1185453085 orthogonal mates and the six place in rating for that square:

0 1 2 3 4 5 6 7 8 9 A B
1 2 0 4 5 3 8 9 A B 6 7
5 3 4 2 0 1 7 8 9 A B 6

7 9 B A 6 8 3 2 4 0 5 1
8 A 6 B 7 9 2 4 0 5 1 3

With your help, we have strictly established that there are not one or two squares with such large number of orthogonal mates, but at least a set!

Post:
Hello evryone, best wishes for new year.
Strange, some WU runs in a few seconds,
But some runs about 30 minuts, then start again from null ! with remaining of some hours !
And those WU, starts again and again !!!
The worst is that such WU (running hours) are considered/reported as working time in a few seconds !
What is the problem ?
My side ?
Best regards


Hello! :)

Most of tasks are short and runs ~ 10 .. 20 seconds. But some tasks (about 1/10 .. 1/20 part of entire set) - long and must runs 1, 2, 3, may be more hours (depending of computer). During computation of this tasks BOINC periodically performs update of estimation run time and percent of completion. And tasks does not have checkpoints.

Thank you for participation!

I can only write about what I know for sure. It is listed in first message and I can repeat it with a few additions.
- The square (about we talk) was discovered by Eduard Vatutin on August 18, 2021.
- Starting from August 26, 2021, the Gerasim@Home project began processing it and the square itself became freely accessible due to the fact that it can be easy read from each of 1.2 million workunits. Starting from this date, I have no opportunity to call other declarations of this square as discoveries.
- After 3 days of recomputing of 480 workunits from 24 October, 2021 until 27 October, Eduard informs me and other colleagues about results of recomputations and obtaining a new value.
- November 11, 2021. The result obtained by CoolAtchOk coincided with the data, obtained by October 27 and thanks to his work with machines, we now have another confirmation of the result (Gerasim@Home, CoolAtchOk, RakeSearch).

Happy new year, dear participants! It's a good time to summarize the results of December!

Millions of workunits computed, three squares completed and now we know slightly more, than in November! The badge of December'2021 is Common tern that lives in middle latitudes of Eurasia and North America and in Kursk region also. (Image source can be found on Birds of the Kursk region page).

Dear participants!

As previously announced (Ru), on August 18, 2021, as part of a separate computational experiment (which did not require calculations in the desktop grid, but is a separate interesting task) Eduard Vatutin found a very interesting diagonal Latin square of order 12 with 30192 diagonal transverses:

0 1 2 3 4 5 6 7 8 9 A B
1 2 3 4 9 8 B 5 A 0 6 7
5 8 A 6 B 4 1 3 9 7 0 2
B 7 5 8 A 2 9 1 3 6 4 0
7 5 8 A 6 3 0 2 4 B 9 1
9 0 1 2 3 7 A B 5 4 8 6
6 B 7 5 8 1 4 0 2 A 3 9
A 6 B 7 5 0 3 9 1 8 2 4
3 4 9 0 1 6 5 A B 2 7 8
2 3 4 9 0 A 7 8 6 1 B 5
4 9 0 1 2 B 8 6 7 3 5 A
8 A 6 B 7 9 2 4 0 5 1 3

This number of transverses was a record (and is so at the moment), which suggested that this square may be accompanied by many orthogonal diagonal Latin squares (ODLS). Search were launched in the Gerasim@Home project, which ended on October 24, 2021 (Ru), issued a record value of the ODLS, but the results obtained were questioned by the authors and declared preliminary, since during processing 7 out of 1214514 results corresponding to one of the 30192 transverses suffered due to a failure in one of the memory banks (which was then replaced). Recomputing of 480 workunits from the "broken" 1421 transversal (Ru) was executed very quickly and by October 27, a new, slightly larger value was already known.
But the following questions remain:
1) How reliable are the calculations performed in grids from a PC? (It is raised at every conference dedicated to supercomputing and grid technologies);
2) The fact that 7 corrupted results were found did not mean that there were only 7 of them;
3) When we talk about calculating this characteristic (as well as many other integer ones), it is important for us to get an absolutely accurate value, even +/- 1 - it will already be incorrect;
4) The project Gerasim@Home is a independent development by SerVal, that compatible with BOINC infrastructure through support of BOINC protocol, but still is not "original BOINC server".
Taking into account the above, the decision was made to perform a complete recomputing for this square in the project Gerasim@Home and two weeks later, on November 5 in RakeSearch project.

On November 11, a sudden help came - information appeared (Ru) that one of the active participants of distributed computing from the Russia Team - CoolAtchOk, using programs based on the algorithm of Alexey Belyshev (whitefox), processed the square of Eduard, obtained a value that coincides with that obtained as a result of recalculation on October 24 - 27.

And today, on the 15th of December, 2021, after conducting a full check in RakeSearch and Gerasim@Home projects, we can confidently say that:
1. The number of ODLS for this record (at the moment) square is 3855983322, which coincides with the values obtained after recalculation of the 1421st transversal and the CoolAtchOk participant;
2. Calculations in PC-based grids are really reliable due to the quorum and we have another "hard argument" to such a question.

What's next? Now the last hundreds of tasks for another square are being counted (square # 5), and the result may be close to a record, also the processing of another one (square # 6) is in full thrust!
